# Blender Batch Rendering
Source: https://docs.vast.ai/blender-batch-rendering
Blender is a free, open source 3D creation suite. It can be used to create animated films, visual effects, art, 3D-printed models, motion graphics, interactive 3D applications, virtual reality, and video games. It supports the entirety of the 3D pipeline—modeling, rigging, animation, simulation, rendering, compositing and motion tracking, even video editing and game creation. You can find more information about Blender at [blender.org](https://www.blender.org/).
Animators, game developers, 3D modelers, visual effects artists, architects, and product designers are some people who use Blender.
GPUs can speed up rendering in Blender.
You can save time by automating away the rendering of animations for batch of blend files.
## Step 1 - Open Vast's Blender Batch Renderer Template
Click on this link [Blender Batch Renderer Template](https://cloud.vast.ai/?ref_id=142678\&template_id=7b570ea8454e5f2b4b026139709fa0e8) to select the vast/blender-batch-renderer template.
## Step 2 - Check the Secure Cloud box if you want a secure machine from trusted datacenters (Optional)
You can narrow your search results to only data center machines if you want insured security standards from our trusted datacenters.
<Frame caption="Highlighted Secure Cloud">

## Step 3 - Filter for a GPU that you feel best suits your needs
If you have questions about which GPU to choose, there is some data around NVIDIA Geforce RTX 4090 giving the best render speed with Blender. You can find other GPUs that work well with Blender here [Blender GPU Benchmarks](https://opendata.blender.org/benchmarks/query/?group_by=device_name\&blender_version=3.6.0). You can also find other options by searching on Google or asking ChatGPT.
The version of Blender running within Vast while using the template linked above at the time of this writing is 3.6.2.
Go to the GPUs filter and check the box for RTX 4090 or another GPU instance.
For example,

This command attempts to bring an instance from the "stopped" state into the "running" state. This is subject to resource availability on the machine that the instance is located on.
If your instance is stuck in the "scheduling" state for more than 30 seconds after running this, it likely means that the required resources on the machine to run your instance are currently unavailable.
Examples:
vastai start instances $(vastai show instances -q)
vastai start instance 329838
```

This command brings an instance from the "running" state into the "stopped" state. When an instance is "stopped" all of your data on the instance is preserved,
and you can resume use of your instance by starting it again. Once stopped, starting an instance is subject to resource availability on the machine that the instance is located on.
There are ways to move data off of a stopped instance, which are described here: [Data Movement](/documentation/instances/data-movement)
```

Performs the same action as pressing the "LIST" button on the site https://cloud.vast.ai/host/machines.
On the end date the listing will expire and your machine will unlist. However any existing client jobs will still remain until ended by their owners.
Once you list your machine and it is rented, it is extremely important that you don't interfere with the machine in any way.
If your machine has an active client job and then goes offline, crashes, or has performance problems, this could permanently lower your reliability rating.
We strongly recommend you test the machine first and only list when ready.

We provide a python CLI (open-source) for a convenient interface to the rest API. You can use the --explain option with any CLI command and it will print out the underlying API calls.
## PyPI Install
You can install the latest stable PyPI release with:
```text Text theme={null}
pip install vastai
```
## Github
Alternatively you can get the very latest version directly from github:
```text Text theme={null}
wget https://raw.githubusercontent.com/vast-ai/vast-python/master/vast.py -O vast; chmod +x vast;
```
This repository contains the open source python command line interface for vast.ai.
This CLI has all of the functionality of the vast.ai website GUI and uses the same underlying REST API.
The CLI is self-contained in the single script file `vast.py`.
## Quickstart
In order to authenticate most commands you will need to first login to the vast.ai website and get an api-key. Go to [https://cloud.vast.ai/cli/](https://cloud.vast.ai/cli/). Copy the command under the heading "Login / Set API Key" and run it. The command will be something like:
`vastai set api-key xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx`
where the `xxxx...` is a unique api-key (a long hexadecimal number).
Note that if the script is named "vast" in this command on the website and your installed script is named "vast.py" you will need to change the name of the script in the command you run.
The `set api-key` command saves your api-key in a hidden file in your home directory.
Do not share your api-keys with anyone as they authenticate commands from your account.
Your default main key allows full access to all commands without limitations, but you can use the CLI to create additional keys with [fine-grained access restrictions](/cli/installation).
## Usage
For the most up to date help, use 'vast.py --help'. You can then get a list of the available commands. Each command also typically has help documentation:
```text Text theme={null}
vastai --help
```
To see how the API works you can use it to find machines for rent.
```text Text theme={null}
vastai search offers --help
```
There are many parameters that can be used to filter the results. The search command supports all of the filters and sort options that the website GUI uses.
To find GPU instances with compute capability 8.0 or higher:
```text Text theme={null}
vastai search offers 'compute_cap >= 800 '
```
To find instances with a reliability score >= 0.99 and at least 4 gpus, ordering by num of gpus descending:
```text Text theme={null}
vastai search offers 'reliability > 0.99 num_gpus>=4' -o 'num_gpus-'
```
The output of this command at the time of this writing is

### Launching Instances
```text Text theme={null}
vastai create instance --help
```
You create instances using the create instance command referencing an instance type ID returned from search offers.
So to create an ssh direct instance of type 2459368 (using the ID returned from the search above for 4x 3090 on machine 4637) with the vastai/tensorflow image and 32 GB of disk storage:
```text Text theme={null}
vastai create instance 2459368 --image vastai/tensorflow --disk 32 --ssh --direct
```
Once an instance is created, it then must first pull the image if it is not cached. After the image is loaded the instance boots and transititons to the running state.
You are charged for the resources you reserve. As storage is reserved at creation, storage charges begin when the instance is created and end only when it is destroyed.
GPU charges begin when the instance transitions to the running state, and end when it is stopped or destroyed.
### Get Instance Info
```text Text theme={null}
vastai show instance --help
vastai show instances --help
```
### Starting Stopping
```text Text theme={null}
vastai start instance --help
vastai stop instance --help
```
You can stop an instance to avoid GPU charges, converting it into a storage unit - storage is usually very cheap compared to GPU.
Starting an existing instance takes only a second or less whereas creating a new instance can take much longer (to pull a large docker image), so maintaining a pool of stopped instances is useful for many applications.
You can [call stop/destroy instance from inside](/documentation/instances/docker-execution-environment) the instance using a special autogenerated instance apikey, to avoid exposing your main apikey.
### Copy Data
```text Text theme={null}
vastai copy --help
vastai cloud copy --help
```
You can copy data from a stopped instance to a running instance, to/from cloud storage, or to/from another machine.
### Destroy Instances
```text Text theme={null}
vastai destroy instance --help
vastai destroy instances --help
```
Once you are done with an instance make sure to destroy it to avoid ongoing storage charges.

# API Endpoints and Permission Categories
This document outlines the various API endpoints and their associated permission categories, providing a clear reference for understanding the access control within our system.
<Note>
**Note:** In the early days we are going to describe these concepts as things like 'instance\_read' or 'instance\_write', We realize these are confusing. Any questions about what permissions are attributed to what actions should be asked via our support channels.
</Note>
Every API Key has a list of permissions associated with it. Every user has the ability to create keys with restricted permissions on their own account. Users can also create restricted keys in team environments using the team-centric endpoints.
### Creating Custom Roles
* **Accessing Role Management**: Custom roles can be created and managed through the CLI. Team roles can be managed on the 'Manage' page by users with team\_read level access.
* **Defining Permissions**: When creating a custom role, anyone can select from a wide range of permissions, such as instance creation, billing access, monitoring, etc. This allows for precise control over what each role can and cannot do.
* **Assigning Custom Roles**: Once a custom role is created, it can be assigned to team members through the team management interface.
### Important Elements
* **constraints**: Constraints can be added at different levels to enforce certain parameters of the body to be specific values
* **params**: You can use wildcards to represent placeholder values. (Useful if you want to generate many keys all doing similar operations)
### Examples
The following json would create a user that has access to the specified categories. In this instance, someone with these permissions would be able to create an instance as well as access billing information
```text Text theme={null}
{
"api": {
"misc": {},
"user_read":{},
"instance_read": {},
"instance_write": {},
"billing_read": {},
"billing_write": {}
}
}
```
The following json would create restricted access to only the presented categories. In this example, someone with these permissions would be able to create an instance, but they would not be able to access billing information
```text Text theme={null}
{
"api": {
"misc": {},
"user_read":{},
"instance_read": {},
"instance_write": {}
}
}
```
You can see a full list of permission types as well as the endpoints attached to that permission below
## Permission Categories
### instance\_read
* [Get Instances](https://docs.vast.ai/api-reference/instances/show-instances)
* [Request Logs](https://docs.vast.ai/api-reference/instances/show-logs)
The following permissions would allow a user to read the instance logs of instance id 1227 only
```text Text theme={null}
{
"api": {
"misc": {},
"user_read":{},
"instance_read": {},
"instance_write": {},
"billing_read": {
"api.instance.request_logs": {
"constraints": {
"id": {
"eq": 1227
}
}
}
}
}
}
```
The following permissions would allow a user to read the instance logs of instance id from $1 to $2. Apikeys using this feature have to be created using the CLI call [create api-key](/cli/commands)
```text Text theme={null}
{
"api": {
"instance_read": {

# CUDA Programming on Vast.ai
## Introduction
This guide walks you through setting up and running CUDA applications on Vast.ai's cloud platform. You'll learn how to set up a CUDA development environment, connect to your instance, and develop CUDA applications efficiently using NVIDIA's development tools.
## Prerequisites
* A Vast.ai account
* Basic familiarity with CUDA programming concepts
* Basic knowledge of Linux command line
* [(Optional) Install TLS Certificate for Jupyter](/documentation/instances/jupyter)
* [(Optional) SSH client installed on your local machine and SSH public key added the Keys section at cloud.vast.ai](/documentation/instances/sshscp)
* [(Optional) Vast-cli installed on your local machine for command-line management](/cli/get-started)
* [(Optional) Docker knowledge for customizing development environments](https://docs.docker.com/get-started/)
## Setup
### 1. Selecting the Right Template
Navigate to the [Templates tab](https://cloud.vast.ai/templates/) to view recommended templates.
Search for [NVIDIA CUDA](https://cloud.vast.ai?ref_id=62897\&template_id=61e14a0dd1f97aa0aa6719d20bc9b02e) template if:
* You need a standard CUDA development environment
* You want pre-configured security features (TLS, authentication)
* You require Jupyter notebook integration
* You need additional development tools like Tensorboard
[Make a custom CUDA template](/documentation/templates/creating-templates) if:
* You need a specific CUDA or Python version
* You have special library requirements
* You want to minimize image size for faster instance startup
### 2. Edit the Template and Select Template
You can edit the template to use Jupyter launch mode if:&#x20;
* You're behind a corporate firewall that blocks SSH
* You prefer browser-based development
* You want persistent terminal sessions that survive browser disconnects
* You need quick access without SSH client setup
* You want to combine CUDA development with notebook documentation
* You plan to switch between multiple terminal sessions in the browser
You can edit the template to use SSH launch mode if:&#x20;
* You're using [VSCode Remote-SSH](https://code.visualstudio.com/docs/remote/ssh) or other IDE integrations
* You need lowest possible terminal latency
* You prefer using your local terminal emulator
* You want to use advanced terminal features like tmux
* You're doing extensive command-line development
* You need to transfer files frequently using scp or rsync
### 2. Create Your Instance
Select your desired GPU configuration based on your computational needs from the [Search tab](https://cloud.vast.ai/create/). For CUDA development, consider:&#x20;
* System Requirements:&#x20;
* RAM: Minimum 16GB for development tools
* Storage: 10GB is usually sufficient
* CUDA Toolkit core: \~2GB
* Development files and builds: \~3-4GB
* Room for source code and dependencies: \~4GB
* CPU: 4+ cores recommended for compilation
* Network: 100+ Mbps for remote development
&#x20;Rent the GPU of your choice.
### 3. Connecting to Your Instance
Go to [Instances tab](https://cloud.vast.ai/instances/) to see your instance being created. There are multiple ways to connect to your instance:
* If Jupyter launch mode is selected in your template:
* Click the "OPEN" button or "Jupyter" button on your instance card&#x20;
* Access a full development environment with notebook support
* If you selected SSH launch mode:
* Click Open Terminal Access button&#x20;
* Copy Direct ssh connect string contents that looks like this "ssh -p 12345 root\@123.456.789.10 -L 8080:localhost:8080"
* You take the ssh command and execute in your terminal in your [Mac or Linux-based computer or in Powershell](/documentation/instances/sshscp)
* You can use [Powershell or Windows Putty tools](/documentation/instances/sshscp) if you have a Windows computer
## Installation
### Setting Up Your Development Environment
1. The base environment includes:
* CUDA toolkit and development tools
* Python with common ML libraries
* Development utilities (gcc, make, etc.)
2. Install additional CUDA dependencies:
```bash theme={null}
apt-get update
apt-get install -y cuda-samples
```
### Configuring Your Workspace
1. Navigate to your workspace:
```bash theme={null}
cd ${WORKSPACE}
```
1. Set up CUDA environment variables:
```bash theme={null}
echo 'export PATH=/usr/local/cuda/bin:$PATH' >> ~/.bashrc
echo 'export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH' >> ~/.bashrc
source ~/.bashrc
```
## Troubleshooting
### Common Issues and Solutions
CUDA not found:
* Check if GPU is detectable: `nvidia-smi`
```linux theme={null}
nvidia-smi
```
If output like "No devices were found" shows up, report the machine after clicking on the wrench icon and rent a different machine.
## Best Practices
### Development Workflow
* Code Organization
* Keep source files in `${WORKSPACE}`
* Use version control for code management
* Maintain separate directories for builds and source
* Performance Optimization
* Use proper CUDA stream management
* Optimize memory transfers
* Profile code using NVIDIA tools
## Advanced Topics
### Custom Environment Setup
Create a provisioning script for custom environment setup:
```bash theme={null}
#!/bin/bash
. /venv/main/bin/activate
pip install additional-packages
wget custom-tools.tar.gz
```
### Remote Development Setup
Configure VS Code or other IDEs for [remote development](https://code.visualstudio.com/docs/remote/ssh):
* Use SSH port forwarding for secure connections
* Configure development tools to use remote CUDA compiler
* Set up source synchronization using Syncthing
## Conclusion
You now have a fully configured CUDA development environment on Vast.ai. This setup provides the flexibility of cloud GPU resources with the convenience of local development.

# Disco Diffusion
Source: https://docs.vast.ai/disco-diffusion
## DEPRECATED: Please see [Stable Diffusion guide](/stable-diffusion)
## Overview
Disco diffusion is an incredibly powerful free and open source AI image generator, which is easy to use on vast.ai. With the right settings and powerful GPUs, it can generate artist quality high-res images for a wide variety of subjects. All of these images were generated purely through DD on vast.ai, without any other tools or clean up.
There are a few ways to run Disco Diffusion on Vast. The simple method is to use the pytorch docker image, plain vanilla jupyter and our slightly modified notebook which you download and then upload into your instance. The core of this guide will detail this method.
<Note>
There is a custom docker image (fork) made specifically to run DD in docker- [jinaai/discoart](https://github.com/jina-ai/discoart). Discoart can spin up somewhat faster and has a number of advanced features beyond the original notebook. Directions for using Discoart on Vast are [here](/disco-diffusion)
</Note>
We have created a video guide that shows all the steps for using Disco Diffusion on Vast:
<iframe className="w-full aspect-video rounded-xl" src="https://www.youtube.com/embed/S4wIFCrKez4" title="How to rent an on-demand GPU for AI image generation using Vast and Disco Diffusion" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen />
## Pytorch image + Jupyter (recommended)
### 1) Select the docker image & config options
Open up the vast console and click on the EDIT IMAGE & CONFIG blue button. Select the pytorch-pytorch image. Click again to open up the config menu. Then select the jupyter-python notebook option.We also recommend checking the box for Jupyter direct HTTPS, although it is not required. To explain the tradeoff- direct HTTPS limits your search to machines with open ports which can be more expensive. HTTPS direct also requires you to install our TLS certificate or click through an "unsafe" warning on your browser. The big benefit is that you get faster download speeds and a more reliable connection. Leaving the box unchecked is fine, you will then connect to Jupyter through one of our proxy servers. It isn't as fast, but doesn't require any further setup.
<Frame caption="Select">
![Select](https://vast.ai/uploads/DiscoDiffusion/Select.png)
</Frame>
### 2) Allocate more disk space
Next you will want to allocate enough disk space. Under the EDIT IMAGE & CONFIG button there is a slider. The default of 10GB can sometimes not be enough. Move the slider up to 15GB or more, especially if you are making videos.
### 3) Select an offer
Here is the fun part! You can now select the GPU you want to rent. For Disco Diffusion, leave the type as "on-demand" as you don't want to be interrupted while generating art.The offers presented to you are limited to machines that can support your image configuration options. Further use the filters to pick a 1X GPU (Disco Diffusion doesn't support more than 1 GPU) and the GPU type. RTX 3090 is a great option. RTX A6000 has more GPU ram which is great for larger models but is more expensive. Other GPUs are also available.Hover over the RENT button to get a breakdown of pricing. Once ready, hit RENT to generate an instance. The instance will now appear in the instances tab and will initialize.### 4) Download the modified DD notebook as a .ipynb fileThe disco diffusion notebooks were created for colab. We made a few slight modifications (to install a few required libs) so they will run on vast.Open the latest modified Disco Diffusion notebook here (5.6) and then file->download->download as ipynb. You then have the ipynb file on your hard drive. You can close the colab tab.Here are all our modified notebooks: ([5.6](https://colab.research.google.com/github/jsbcannell/misc/blob/master/Disco_Diffusion_v5_6_vastai.ipynb), [5.4](https://colab.research.google.com/github/jsbcannell/misc/blob/master/Disco_Diffusion_v5_4_vastai.ipynb), [5.2](https://colab.research.google.com/drive/13zKUZDqOLbfbVdceW8eyfNZ_mRNVPbBP?usp=sharing#scrollTo=InstallLibs) )
### 5) Open the Jupyter instance
Navigate to the instances in your account. You should see your instance booting up. Once it is ready, click on the OPEN button to open the Jupyter interface. Note that it can sometimes take an additional 30-60 seconds for Jupyter to start after the button appears. If you get an error, wait a while and then reload.

</Frame>
### 6) Run the modified DD notebook
Once you can connect to the instance, you will see the Jupyter logo and a few files. Click on the upload button in the upper right and upload the .ipynb file from 4. Once that uploads, click on the notebook to open it.
<Note>
If you are used to Google colab, the interface for vanilla Jupyter is similar with some differences. One thing you will notice right away is that there are no clean input boxes/check boxes for modifying the settings. Scroll through the notebook and change the settings in the code directly.
</Note>
Review section 2. Diffusion and CLIP model settings to see if there are any clip settings you want to change. Getting into the specifics of matching CLIP settings to your GPU (and GPU RAM) is beyond the scope of this guide. Join the Disco Diffusion Discord for help.
Change the Prompts at the end of section 3. Doing a quick Ctrl+F and searching for 'A beautiful painting' is a quick way to find the prompt settings. Modify the prompt to whatever art you want to generate.
**Now it's time to Disco!**
Once you have customized your settings, select Cell->Run All to start. The code will start to execute from top to bottom. The first couple of cells will install libs and download the CLIP models. This can take 5-15 minutes. The output of the code will appear in a text box.

</Frame>
Scroll down to the bottom of the notebook to the end of step 4. Right above step 5 you should see the in-progress image.

</Frame>
### 7) Changing settings and downloading images
After each image generates, it is placed into the images\_out/TimeToDisco folder. You can then review your artistic creations. They are easy to download individually.After a while you will want to change the prompt or settings. When the notebook is running, any changes that you make to it will not save. For example, if you change the prompt, the notebook will not start working off that prompt. After each setting change, you will need to hit the >> button to restart the kernal and then to run all the cells again. The second time through it will not need to download any models and so should be fast.
### Zipping up all your images
If you end up generating tens or hundreds! of images, there is a way to zip them up into a single file and then download them all. To more conveniently download folders or a number of files, you can use the command line zip tool. First open a new terminal by clicking New->Terminal:
<Frame caption="Spaces Mgwtdaam0Bo2Skpvyo6Q Uploads Nggbmr0I6L36Rzek1Izx Image">
![Spaces Mgwtdaam0Bo2Skpvyo6Q Uploads Nggbmr0I6L36Rzek1Izx Image](https://vast.ai/uploads/crawl/spaces_mgwtdaam0bo2skpvyo6q_uploads_nggbmr0i6l36rzek1izx_image.png)
</Frame>
Then in the terminal copy and paste the following:
```text Text theme={null}
apt-get install -y zip
```
Hit enter to run those commands which will install the tool. Then to zip all of the files in the default images\_out/TimeToDisco directory:
```text Text theme={null}
zip all_images.zip images_out/TimeToDisco/*
```
Note: do no use spaces in your folder names, they cause headaches on linux! Use the '\_' underscore instead.
### Additional help
For discussion/help/advice running DD on vast find us on our discord, and make sure to check out the main DD discord .
## Custom docker image - Discoart
Instead of the pytorch image, you can use the custom jinaai/discoart docker image. Discoart can spin up somewhat faster and has a number of advanced features beyond the original notebook. To use it, the steps are similar but instead of picking the pytorch-pytorch image you select a blank template slot and then paste in the following docker image name:
```text Text theme={null}
jinaai/discoart:latest
```
Also in the second line, use the following option to set the ENV variable:
```text theme={null}
-e JUPYTER_DIR=/
```
<Frame caption="Jinai">
![Jinai](https://vast.ai/uploads/DiscoDiffusion/Jinai.png)
</Frame>
Follow steps 2) and 3) to allocate more disk space and select an offer.
Discoart has the notebook installed already in the docker image. So once Jupyter starts, hit the connect button to connect to Jupyter. Install our TLS cert (if you haven't already) for the direct HTTPS connection or else you will get a browser warning.
Open the discoart folder and then open the discoart notebook. Change the prompt and any settings you want to modify. Then select Cell->Run All to start the notebook. The results should start to appear quickly because the custom docker image already has downloaded the models.

* **For Jupyter access**: download and install the provided [TSL certificate](/documentation/instances/jupyter#1SmCz) (needed for secure browser access).
<Note>
If you don’t install the provided browser certificate:&#x20;
* **Windows / Linux** – You’ll see a **“Your connection is not private”** privacy warning. You can still connect by clicking **Advanced** → **Proceed**, but the warning will appear every time.
* **macOS** – Browsers will block Jupyter until you install and trust the provided certificate in **Keychain Access**. Without it, you won’t be able to connect.
Installing the certificate once removes the warning permanently.
</Note>
### &#x33;**. Pick a&#x20;**[**Template**](/documentation/instances/templates)**&#x20;& Find a Machine**
* Browse [**Templates**](https://cloud.vast.ai/templates/) for pre-built setups (e.g., [PyTorch](/pytorch), TensorFlow, ComfyUI).
* Go to [**Search**](https://cloud.vast.ai/create/) and filter by GPU type, count, RAM, CPU, network speed, and price.
* **Disk Space is Permanent.&#x20;**&#x54;he disk size you choose when creating an instance cannot be changed later. If you run out of space, you’ll need to create a new instance with a larger disk. Tip: Allocate a bit more than you think you need to avoid interruptions.
* Click **Rent** when you find a match.
* Wait for the instance to start—cached images launch quickly, fresh pulls may take 10–60 minutes.
* Click **Open** button to access your instance.
### **4.&#x20;**[**Manage or End Your Instance**](/documentation/instances/managing-instances)
* Use **Stop** to pause GPU billing (storage still accrues charges).
* Use **Delete** when finished to stop *all* charges.

## Common Questions
### What is a minimum deposit amount?
The minimum deposit amount on Vast.ai is \$5.
### What happens when my balance runs out? Can I avoid interruptions?
When your balance reaches zero, your running instances will automatically stop. To avoid this, you can enable **auto-billing&#x20;**&#x6F;n the Billing page. Set an auto-charge threshold higher than your average daily spend, so your card is automatically charged when your balance falls below that amount. We also recommend setting a **low-balance email alert&#x20;**&#x61;t a slightly lower threshold to notify you if the auto-charge fails for any reason.&#x20;
### How can I customize a template?

# Introduction
Vast is introducing support for several features (local VPNs for client instances \[in beta], network volumes \[in alpha]) that depend on the host's LAN configuration.&#x20;
Hosts can now register a set of machines they own sharing a LAN as a cluster to allow clients renting their machines to access local network resources. This will allow their machines to support use cases such as multi-node training via NCCL; as well, this will be a prerequisite to listing network volumes when they are released.&#x20;
A registered *cluster* is associated with:
* A machine that acts as the *manager node* and is responsible for dispatching cluster management commands from the Vast server.
* An IP *subnet* that machines in the cluster use to identify which network interface / which IP addresses for communication with other machines in the cluster.&#x20;
* A set of *member* machines.&#x20;
The requirements for a set of machines to be registered as a cluster are that every member machine has a (non-NATed) IP address in the cluster's subnet to which any other machine in the cluster can communicate with on all ports.
# Cluster registration guide
* Update to the newest version of the CLI: go to ([https://cloud.vast.ai/cli/)\[https://cloud.vast.ai/cli/](https://cloud.vast.ai/cli/\)\[https://cloud.vast.ai/cli/)] and copy+run the command starting with `wget`.
* Identify and test the subnet to register:
* On the manager node ---
* Run `ip addr` or `ifconfig` (the `ip` utility is part of the `iproute2` package).&#x20;
* Identify which interface correspond's to their LAN. For most hosts this will be an ethernet interface, which have the naming format `enp$BUSs$SLOT[f$FUNCTION]]` in modern Ubuntu.&#x20;
* Hosts using Mellanox devices for their main ethernet connection may instead see their interface show up as `bond0`
* Find the IPv4 subnet corresponding to that network interface --&#x20;
* In `ip addr` output, the third line for each interface usually starts with `inet IPv4SUBNET` where `IPv4SUBNET` has the format `IPv4ADDRESS/MASK` where `MASK` is a non-negative integer \< 32.
* Test that the other machines to be added to the cluster can reach the manager node on that subnet/address.&#x20;
* On the manager node:
* run `nc -l IPv4ADDRESS 2337` where `IPv4ADDRESS` is the IPv4 address component of the chosen subnet.&#x20;
* On each other node:
* run `nc IPv4ADDRESS 2337`
* Type in some test text (i.e., "hello") and press enter
* Check that `nc` received and outputed the test text on the manager node.&#x20;
* Run `./vast.py create cluster IPv4SUBNET MACHINE_ID_OF_MANAGER_NODE`
* Run `./vast.py show clusters` to check the ID of the cluster you just created.&#x20;
* Run `./vast.py join cluster MACHINE_IDS` where `MACHINE_IDS` is a space seperated list of the remaining machines to add to your cluster.&#x20;
# Cluster Management Commands Reference
* `./vast create cluster SUBNET MANAGER_ID`&#x20;
* Initializes a cluster containing the machine with ID `MANAGER_ID` as its manager node and using the network interface corresponding to `SUBNET`
* `./vast show clusters`
* Shows clusters, for each cluster showing its `CLUSTER_ID`, associated `SUBNET`, manager node machine\_id, and list of member machines.&#x20;
* `./vast join cluster CLUSTER_ID MACHINE_IDS`
* Takes `MACHINE_IDS` as a space seperated list, and adds them to the cluster specified by `CLUSTER_ID`
* `./vast remove-machine-from-cluster CLUSTER_ID MACHINE_ID [NEW_MANAGER_ID]`
* Removes machine `MACHINE_ID` from cluster `CLUSTER_ID`. If the machine is the only manager, another machine in the cluster `NEW_MANAGER_ID` must be specified so that the cluster still has a manager.&#x20;
* `./vast delete cluster CLUSTER_ID`
* Deletes cluster `CLUSTER_ID`. Fails if cluster resources are currently in use by client instances.&#x20;

Starting November 1st, 2023: Stripe will email you instructions on how to set up e-delivery and create a Stripe Express account. If you haven’t already, you’ll need to complete these steps to access your 1099 tax form electronically.
Before mid January: Confirm your tax information (e.g., name, address, and SSN or EIN) is correct via Stripe Express.
By January 31st, 2024:
Your 1099 tax form will be available to download through Stripe Express.
Your 1099 tax form will be mailed to you if you don’t receive an email from Stripe or don’t consent to e-delivery. Please allow up to 10 business days for postal delivery.
Vast.ai will file your 1099 tax form with the IRS and relevant state tax authorities.
April 15, 2024: IRS deadline to file taxes. You’ll need your 1099 tax form to file your taxes.
In January, we strongly suggest that you make sure all of your tax filing details and delivery preferences are up to date in Stripe Express. Your name, address, and Taxpayer Identification Number (Social Security Number /Employer Identification Number) are of primary importance.
### I earned enough to need a 1099 form in 2023. Why haven’t I received an email from Stripe?
If you earned enough to need a 1099 form in 2023, you should have received an email from Stripe by mid-January 2024. Emails for pre-filing confirmation will be sent out starting Nov 1, 2023 - this is separate from the email you’ll receive when your form is filed by the platform in January.
If you can’t find an email from Stripe, it’s possible that:
* The email may be in your spam/junk mail folder. Please search your inbox for an email titled: “Get your Vast.ai 2023 tax forms faster by enabling e-delivery”.
* Vast.ai does not have your most current email address on file. Please check any other email addresses you may have used to sign up for Vast.ai, or reach out to Vast.ai to update your email and have an invite email sent to you.
* The email address associated with your Vast.ai account is incorrect, missing, or unable to receive mail.
You may not have received an invitation for other reasons, such as:
* You earned less than the threshold for your form type.
* Your email address on file is incorrect, missing, or unable to receive email.
* Your specific account is unsupported on Stripe Express (in uncommon situations where multiple users are sharing the same account, or the same email address is being used on more than 20 accounts)
### Will I receive a 1099 form?
If you earned less than $600 over the course of the year, you may not receive a 1099 form and one won’t be generated for you unless you meet a threshold in your state. If your state has a filing threshold lower than $600, you might receive a 1099 form.
You can check your state’s requirements here: View [1099 state requirements](https://stripe.com/docs/connect/tax-forms-state-requirements#check-1099-form-requirements-by-state).

Vast is a GPU marketplace. Hosts sell GPU resources on the marketplace. Hosts are responsible for:
* Setup: installing Ubuntu, creating disk partitions, installing NVIDIA drivers, opening network ports on the router and installing the Vast hosting software.
* Testing and troubleshooting all issues that can arise, such as driver conflicts, errors, bad GPUs, and bad network ports. **Vast does not offer support for getting your machine working.** There is a [host discord](https://discord.gg/hSuEbSQ4X8) with helpful members and the host-general channel is searchable for specific errors.
* Managing the listings and GPU offers for rentals, including setting pricing and end dates for the offers
* Planning for maintenance so that no client jobs are affected
## Account setup and hosting agreement
You must create a new account for hosting. If you are using Vast.ai as a client, do not use the same account. A single client and hosting account is not supported and you will quickly run into issues.
Once your account is created, open the [host setup guide](https://cloud.vast.ai/host/setup/). There is a link in the first paragraph to the hosting agreement. Read through the agreement. Once you accept, your account will then be converted to a hosting account. You will notice there is now a link to Machines in the navigation, along with some other changes. Your account can now list machines that are running the daemon software.
## Machine setup
The [host setup guide](https://cloud.vast.ai/host/setup/) is the official documentation for setting up a machine on Vast.ai. Read through each section closely.
Common issues to check:
* Make sure to test the networking. Clients require open ports to directly connect to the machine for most jobs.
* Make sure to read the section on IOMMU if you have an AMD EPYC system.
* Make sure to disable auto-updates so that your machine doesn't drop a client job to update a driver.
Once you are ready to list your machine, come back to this guide to understand pricing and listing the rental contract.
## General concepts
Clients have high expectations coming from AWS or GCP.
As a host, plan to offer 100% uptime for your machine during the contracted period.
Expect that the GPU is going to be used at close to max capacity for the rental period.
Ensure that your Internet, power source and heat dissipation systems are all functioning and that you have thought through how hosting will affect each one of those items.
## Listings and Contracts
Hosts can create machine *listings* (offers) through the CLI command list machine or the machine control panel GUI on the host machines page.
The main listing parameters include:
* the pricing for GPUs,internet,storage
* the discount schedule param which determines the price difference between [on-demand](/documentation/instances/rental-types) and [reserved](/documentation/instances/rental-types) instances
* the min bid price for [interruptible](/documentation/instances/rental-types) instances
* the min\_gpu param controlling 'slicing' (explained below)
* the end/expiration date which determines how long the listing lasts
The listing offer is good until the end date.
When a client creates an instance on your machine, this creates a *contract* from your listing.
Once you list and get rental contracts, it is very important to honor the terms of the contract until the end date.
## The Rental Contract
By listing your machine or compute services, you are offering up a rental contract to potential clients.
Once a client accepts this listing, you and the client have entered into a rental agreement - a contract.
As the provider you are *promising* to provide the services as advertized in your listing:
* the provider must provide the hardware/services according to all the advertized specs
* the hardware can not be used for any other purposes
* the client's data must be isolated and protected according to the data protection policy
* the advertized services must be provided up until the end date (contract expiration)
For full details, see the [hosting agreement](https://cloud.vast.ai/host/agreement) and [Service Level Agreement](https://cloud.vast.ai/host/SLA_default).
### Expiration date (end date)
The expiration date can be set in the hosting interface by clicking on the date field under expiration and selecting a date for when the listing contract will expire.
The CLI command to 'list machine' includes a field for end date, which is the same date.
Make sure to set an end date **before** listing your machine, or else the listing will not expire.
The "client end date" is the date of the longest client contract on a given machine.
### Min GPU
When clicking on the set pricing button, there is a min GPU field. The min GPU field allows you to set the smallest grouping of GPU rentals available on your machine in powers of 2, or down to 1. For example, if you have an 8X 3090 and set min gpu to 2, clients can create instances with 2, 4, or 8 GPUs. If you set min gpus to 1, then clients can make instances with 1, 2, 4 or 8 GPUs.
### On-demand Price
The on-demand price is the price per hour for the GPU rental. On demand rentals are the highest priority and if met will stop interruptibles.
### Interruptible min price (optional)
The interruptible price allows for the host to set the minimum interruptible price for a client to rent. Interruptibles work in a bidding system: clients set a bid price for their instance; the current highest bid is the instance that runs, the others are paused. [more info](https://vast.ai/faq#RentalTypes)
### Reserved Discount Pricing Factor
Reserved Instance Discounts are a feature for clients which allows them to rent machines over a long period of time at a reduced price. The Reserved Discount Pricing Factor represents the maximum possible discount a user can achieve on your machines.
The reserved discount pricing is determined by the hosts. If you intend to encourage a long term rental this is a factor that you may want to research. Use the filters in the UI to select reserved.

This discount is not static, but rather scales over time that the user rents the machine for. These values are determined by the individual host(s).
As a host, you can set this number yourself to 0 if you wish to opt out of this feature.
## Volume Contracts
In addition to GPU contracts, hosts can now offer volume contracts on machines. This is a contract for storage space, and can be priced separately from GPU contracts. The space allocated for storage contracts is in the same pool of space as that for GPU contracts, meaning that space will not be subtracted from available offers unless it is in use.&#x20;
When a client rents a volume listing, they rent a subset of the total space set for the listing, up to the total amount.
### Storage Usage
Allocated storage (that is, storage in use by client contracts) is subtracted from the total storage available on a machine, and split up proportionally among the machines GPUs in remaining ask contracts.
For example, on a machine with 1000Gb of disk available and 2 GPUs, a host can create a volume listing of up to 1000 Gb.&#x20;
If they create a volume listing of 500 Gb, and it is not rented, the machine will be available for rent with 2 offers of 1xGPU 500Gb and 1 offer of 2xGPU 1000Gb.&#x20;
If 200 Gb of the volume contract are rented, the GPU offers will reduce to 2 1xGPU 400Gb offers and 1 2xGPU 800Gb offer. The volume contract will still remain, as there is still available space, and update to offer 300Gb.&#x20;
Similarly, if stored instances on the machine are taking up 800Gb, the volume offer will reduce to 200Gb.
If stored instances are only taking up 400 Gb, the volume offer will not update, as there is still enough space on the machine to cover the volume offer.
### Listing Volumes
By default, volume offers will be listed with contract listings at the same disk price for half of the available space on the machine. Only rented space will impact the amount of space available for contract offers, not the space in the listing itself. You can control the amount of space listed with the -v CLI option, and the price of the space with the -z option.
Space is listed in Gigabytes, and price in \$/Gb/Month.
```text Text theme={null}
vastai list machine <machine_id> -v <space> -z <price> -g .5 -e "12/23/2027" -r 0 -m 1
```
You can also directly list available space for volume contracts by running the `vastai list volume` command.
```text Text theme={null}
vastai list volume <machine_id> -s <space> -p <price>
```
<Warning>
Volume offer end dates **must** align with normal contract offer end dates.&#x20;
Setting an end date on a volume will not update if there is an existing contract offer.
Setting a contract offer end date will update volume offer end dates.
</Warning>
Volume contracts will be unlisted when the machine is unlisted. They can additionally be unlisted with the command:
```text Text theme={null}
vastai unlist volume <volume_id>
```
### Out of sync Contracts
When a client deletes a volume, the space is automatically freed on the machine. If the machine is offline at this time, there is a job that runs hourly to free the space. If for some reason this is not working, or if you want to free the space automatically, you can run the command
```text Text theme={null}
vastai cleanup machine <machine_id>
```
This will automatically remove expired/deleted contracts from the machine, and available storage will update on offers.
## Extending contracts
To extend the current contracts for all clients on a given machine, change the expiration date to a later time with the same or lower pricing.
If you have raised the pricing, you cannot extend the current contract.
## Testing your own machine
It is vital to test your own machine to ensure the ports and software is running smoothly.
### Setup a separate client account
There are two supported ways to test your own machine. If you want to use the website GUI, you will need to setup a new account on a different email address, add a credit card and then find your machine and create instances on it like a client. This has the benefit of showing you the entire client experience. Testing the recommended Pytorch template is vital to ensure that SSH and Jupyter are working properly.
### Use the CLI (preferred)
The preferred method of testing your own machine is to run the [CLI](https://cloud.vast.ai/cli/). For Windows users, we suggest setting up [WSL](https://learn.microsoft.com/en-us/windows/wsl/install) which will require you to install Ubuntu on your Windows machine and change your bios settings to allow virtualization. Then you can start an Ubuntu terminal and run the CLI.
To rent your own machine you will need to first search the offers with your machine ID to find the ID and then create an instance using that ID. The show machine command will show all your connected machines.
```text Text theme={null}
./vastai show machines
```
Then for each machine id you will need to find the available instance IDs.
```text Text theme={null}
./vastai search offers 'machine_id=12345 verified=any'
```
Replace 12345 with your actual machine ID in question.
You can see the number of available listings as well as information about the machine. This is the fastest way to also see all the offers listed for a given machine.
The website GUI stacks similar offers and so it is not easy to see all the listings for a given machine. That is not a problem for the CLI.
Take the ID number from the first column and use that to create a free instance on your own machine. This example loads the latest pytorch image along with both jupyter and ssh direct launch modes.
```text Text theme={null}
./vastai create instance <ID> --image pytorch/pytorch:latest --jupyter --direct --env '-e TZ=PDT -p 22:22 -p 8080:8080'
```
You can then look at your [instance tab](https://cloud.vast.ai/instances/) to make sure that pytorch loaded correctly along with jupyter and ssh. Click on the \<\_ button to get the ssh command to connect to the instance. Test the direct ssh command. Click on the open button to test jupyter. If the button is stuck "connecting" then there is most likely a problem with the port configuration on the router in front of the machine. Once finished, destroy the instance.
## Maintenance
The proper way to perform maintenance on your machine is to wait until all active contracts have expired or the machine is vacant.
Unlisting will prevent new contracts from starting on the machine. However if you have a current client rental, you could set the end date to the client end date to allow for other clients to create instances on that machine that expire at the same date. Once the end date is reached, you can then unlist the machine and then perform maintenance.
For unplanned or unscheduled maintenance, use the CLI and the schedule maint command. That will notify the client that you **have** to take the machine down and that they should save their work. You can specify a date and duration.
## Uninstalling
To uninstall, use the Vast uninstall script located at [https://s3.amazonaws.com/vast.ai/uninstall](https://s3.amazonaws.com/vast.ai/uninstall).
## Common Questions
### How do I host my machine(s) on Vast? How can I rent my PC?
Hosting on Vast will require some Linux knowledge, as you will be maintaining a server. Our setup guide is [here](https://vast.ai/console/host/setup/). After the first paragraph of the guide there is a link to the hosting agreement. Once you agree, your account will be converted to a hosting account. You can review our [FAQ](https://vast.ai/faq/#Hosting-General) that answers many of your hosting questions.
### How do I get an invoice?
You can create an invoice by going to the "Billing" page, and then click the box for "Include Charges" under "Generate Billing History".
### How do I check if my machine is listed?
If your machine seems unlisted, try this command `vastai search offers 'machine_id=MACHINE_ID verified=any'` to see if the CLI finds it. If there is a result, your machine is properly listed
### Can you verify my machine?
Verification is conducted in a randomized and automated fashion. We only run manual verification tests are for datacenters and high end machines.
### How does verification work?
Verification is mostly for higher end machines, mining rigs may never be verified.
Verification is also based on supply vs demand and is machine/gpu specific.
Right now the only machines which can expect fast verification are \$10k+:
H100 or A100 80GB - if not tested quickly in a day or so let us know.
8x4090, 4xA6000 - should be tested in less than a week, especially if you have a number of them
The only manual verification tests are for datacenters and high end machines.
For everything else we run more random auto verification roughly about once a week.
For datacenter partner inquiries email us at [contact@vast.ai](mailto:contact@vast.ai) directly.
### How do I gain datacenter status?
To apply for datacenter status we have a number of requirements. There is a minimum number of servers and the datacenter where the equipment is located will need to have a third party certification such as ISO 27001. Please read the complete requirement list and application instructions [here](/documentation/host/datacenter-status).
### How do I uninstall vast from my machine?
You can use the [uninstall script](https://s3.amazonaws.com/vast.ai/uninstall)
### Help I am getting this error on my machine?
For help with machine setup, specific questions about hardware, and for errors or other issues, go to [our discord](https://discord.gg/hSuEbSQ4X8).
### Why is my machine not listed?
You won't be able to see it on the GUI right away, but you can search using the [CLI](/documentation/instances/managing-instances).
### Can I send a message to a customer using my machine letting them know that I fixed an issue that they were having?
No, there is not an established process for hosts to message customers on Vast.
### I fear I will decrease my reliability from restarting my machine and potentially lose my verification.
Your machine's reliability does not directly affect your verification standing. Verification is independent of reliability. Though, whenever taking your machine offline and working on it you should procede with caution as it is easy to introduce new issues or errors that will cause your machine to be de-verified.
### How much can I make hosting on Vast?
To get an understanding of prices, the best place is 500farms which is a third party website that monitors Vast listings. The link is [here](https://500.farm/vastai/charts/d/a6RgL05nk/vast-ai-stats).
### Why did the reliability on my machine decrease?
If the machine loses connection or if there is a client instance that does not want to start the machine's reliability will drop.
### How do I minimize my reliability dropping?
Do not take your machine offline. If you must take your machine offline, minimize the time you have it offline. Note: reliability takes into account the average earnings of the machine, and machines with less earnings get penalized less from offline time.
### If someone has already used an image on my machine does redownload happen or is the system smart?
Prior images are cached.
### My storage for clients is somehow full. I just have a few jobs stored in my server and most of them are old and didn't delete once the job finished. A lot of them are really old, can I remove them to free up some space?
We suggest that you try cleaning up the docker build cache, as it sometimes frees up far more space than it claims. You can also clean up old unused images.
### I can't find my machine?
If your machine seems unlisted, try this command `vastai search offers 'machine_id=MACHINE_ID verified=any'` to see if the CLI finds it. If there is a result, your machine is properly listed.
### Why can't I see my machine on the Search page in the console?
There are over 10,000+ listings on Vast, and search only displays a small subset. You will usually not be able to find any one specific machine through most normal searches. This is expected and intentional behavior of our system. You can use `vastai search offers 'machine_id=MACHINE_ID verified=any'`, to see your machine's listing. If you want to get an understanding of the machines ranking above yours you can use very narrow filters to see what similar machines are ranking above you. For example, something like: `vastai search offers 'gpu_name=RTX_4090 cpu_ram>257 cpu_ram<258'` is a decently constrained search that will most likely include a given machine you are looking for (that fits these filters) amongst others that are similar. Keep in mind our Auto Sort that `search offers` defaults to is comprised of both ranking various factors as well as an element of randomness.

## Common Questions
### When will I get paid?
It takes 2 weeks to get your first payout. The pay period ends and goes pending, then you are paid for that pay period the following Friday.
### Why does it show paid on my invoice when I don't see the payment in my account yet?
The paid status on invoices is marked as such when we send the payment list out to Paypal, Wise, Stripe, etc. This does not accurately represent the payment's status within Paypal, Wise, Stripe, etc., bu rather shows the status of the payment solely within our system.
### Can I generate an invoice?
You can create an invoice by going to the "Billing" page, and then click the box for "Include Charges" under "Generate Billing History".
### How much can I make hosting on Vast?

Verification follows a transition flow like this: unverified -> verified -> deverified -> unverified -> ....
Verification is mostly for higher end machines, mining rigs may never be verified.
Right now the only machines which can expect fast verification are \$10k+: H100 or A100 80GB
If you have a higher end machine that is not tested quickly in a day or so let us know.
8x4090, 4xA6000 - should be tested in less than a week, especially if you have a number of them.
For machines that are not high-end machines or machines from datacenters, verification is relatively random even if your unverified machine is meeting these requirements.
We run more random auto verification roughly about once a week.
The only manual verification tests are for datacenters and high end machines.
For datacenter partner inquiries email us at [contact@vast.ai](mailto:contact@vast.ai) directly.
You can use the [vast cli](https://github.com/vast-ai/vast-cli) "self-test machine" command to see if a machine meets all of the requirements, resolve any issues, and have a better chance of getting verified.
## Unverified
These are typically new machines that have not been tested by Vast's team/software.
In order for your unverified machine to be verified, it must follow these minimum guidelines:
```text Text theme={null}
Ubuntu 18.04 or newer (required)
Dedicated machines only - the machine shouldn't be doing other stuff while rented
Fast, reliable internet: at least 10Mbps per machine.
10-series Nvidia GPU or MI25 or newer Radeon Instinct series GPU or Radeon VII or Radeon Pro VII or Radeon RX 7900 (GRE/XT/XTX); or Radeon Pro W7900/W7800. Other 6000 series or newer Radeon RX/Pro W series GPUs may be supported; but may not be searchable using standard filters for AMD ROCm.
At least 1 physical CPU core (2 hyperthreads) per GPU.
Your CPU must support AVX instruction set (not all lower end CPUs support this).
At least 4GBM of system RAM per GPU.
Fast SSD storage with at least 128GB per GPU.
at least 1X PCIE for every 2.5 TFLOPS of GPU performance.
All GPUs on the machine must be of the same type.
An open port range mapped to each machine.
```
The ideal machine will exceed these minimum guidelines, as some workloads require even more CPU, RAM, disk, and PCIE performance. Also keep in mind that everything scales with GPU power, so a 3090 will need more ram, a better cpu, etc, than a 3060.
Note that changing components that degrade machine performance (e.g, decreasing the number of GPUs, RAM capacity, etc) is not supported after the machine is created, and will result in the machine being deverified. Upgrading the machine is ok (e.g, increasing the number of GPUs, RAM capacity, etc), but it will take some time before the change is reflected in search.
In order for your unverified machine to be verified, it must also meet the following minimum requirements:
```text Text theme={null}
CUDA version greater than or equal to 12.0
Reliability of 90%
At least 3 open ports per GPU (100 recommended)
Internet download speed of 500 Mb/s
Internet upload speed of 500 Mb/s
GPU RAM of 7 GB
```
## Verified
If you've been verified by meeting those minimum requirements and having your machine being randomly selected or having higher end machine(s) or datacenter(s), continue to meet these requirements and try to prevent the issues listed in the Deverified section of this guide.
## Deverified
Your machine could go from verified -> deverified if an error in your machine is autodetected.
If you see a red error on your machine card, you should try to investigate and resolve that because it could get you deverified.
Some issues that could get your machine deverified are issues with a container starting in your machine, nvidia-smi related errors, nvml errors, nvidia-container-cli device errors, or issues with verifying the bandwidth of your machine.
If the issue is resolved, then your machine will go from deverified -> unverified.
# Finding & Renting Instances
Source: https://docs.vast.ai/documentation/instances/choosing/find-and-rent
Find and rent GPU instances on Vast.ai. Learn how to search, filter, understand offer cards, and configure your instance.
The search page is the main portal for finding good machines and creating instances on them.
<Note>
Before renting an instance, you'll need to select a template that defines your Docker image and connection method. If you haven't already, review [Choosing a Template](/documentation/instances/choosing/templates) to understand your options.
</Note>
# Page Walkthrough
## Layout
You will find various search options on the top and left control bars that allow you to filter for various criteria (location, GPU type and count, various hardware specs, rental params, etc)
## Offer card
The offer card contains detailed information about the offer available for rent. Once rented, the offer then becomes a contract between you and the host. The offer card details the terms of the contract along with the specs of the available instance.
Most of the items on the offer card can be filtered using the search filters. Some of the important parts are the price and the maximum length of the rental (max duration). Hovering over the price details the different prices for GPU rental, storage and bandwidth.
### Machine Tiers
One important concept is the category of machine which is displayed on the offer card.
* Unverified: These are typically new machines that have not been tested by Vast's team and are filtered out of results by default
* Verified: These machines have passed our internal tests
* Datacenter: These machines are verified and confirmed to be in a certified datacenter that meets our datacenter criteria. Vast verifies that these machines are in a datacenter with a TIER 2/3 rating or ISO 27001. These offer cards have a blue label and are recommended for production
### Card Details
<Frame caption="Offer Card">
![Offer Card](https://vast.ai/uploads/offer-card.PNG)
</Frame>
All stats shown are the portion of the total machine rented.
* Location and Host ID: The general region and ID of the host. Datacenter machines are labeled in blue.
* GPU Model: The GPU type and number
* Performance: The total TFLOPS of the GPU(s)
* GPU Memory: The GPU RAM per card and GPU memory bandwidth in GB/s
* Motherboard: The name of the motherboard manufacturer and type
* Motherboard details: PCIE version and number of lanes along with maximum theoretical PCIE bandwidth in GB/s
* CPU: The CPU type
* CPU Cores: the number of cores allocated for this offer divided total
* System RAM: system RAM allocated for this offer divided by the total
* Network Bandwidth: Given in Mbps for upload/download
* Network Ports: number of potential ports available
* Storage: The type of disk
* Disk speed: The speed of the local storage on the machine in MB/s
* Total available disk: The maximum amount of disk space available
* DLPERF score: A custom deep learning performance score
* Price: The GPU rental price plus the hourly cost of the storage allocated. Hover over the price for a breakdown and for the price of bandwidth.
* Max Duration: The duration of the contract
* Reliability: A score of how reliable the machine has been. All machines start at 60% reliability.
Rental Option: RENT Button
## Instance Disk Size
The storage slider is both a search filter and a parameter input which determines the storage allocation size - it's important to size this correctly before creating any instance.
When the instance is created, the disk size is set and cannot be modified. It is important to estimate how much disk you will need and then to move the slider to the desired disk size. The default disk size for an instance is 10GB. Use the slider to allocate more or less, taking into consideration that providers charge for disk allocation even when the instance is stopped.
<Frame caption="Disk Space">
![Diskspace](https://vast.ai/uploads/Search/DiskSpace.png)
</Frame>
## Instance Configuration
Vast.ai provides out Linux docker instances. One key step during setup is specifying what Linux docker image to load. You can also specify Docker run commands, an on-start script that executes bash commands on instance start and a launch mode to connect to the instance.
The instance configuration menu is accessible in the upper left of the create instance interface. The current template is always displayed in the upper left.
Click on the "Change Template" button to bring up the template config menu that allows selecting and editing templates. For a quick overview, see [Choosing a Template](/documentation/instances/choosing/templates). For detailed template creation and Docker configuration, see the main [Templates documentation](/documentation/templates/introduction)

## Common Questions
### I can't search for instances. I am getting the error "Error: invalid\_request 0 is not a valid search op"
Reset your filters. There is probably an invalid entry in your extra filters section on the template you are currently using.
### I can't find the machine type I am looking for?
Please search to see what is available, using our Search page or `vastai search offers`. Please keep in mind that we are only a marketplace. We do not manage or provide the hardware. If there is nothing available there is little we can do.
### When I try to rent an instance I get "Error: server\_error Something went wrong on the server"
Although this error can be due to a variety of things, we recommend checking to make sure you have a version tag on your Docker Image in your template. It should look like YOUR\_DOCKER\_IMAGE\_PATH for example "pytorch/pytorch". Selecting "latest" in the Version Tag dropdown menu in the template editor should fix this for you if you have a null tag or no tag selected.
### Why did I get "offer is no longer available"?
If you get this error when clicking the RENT button, the specific machine/GPU slot you requested is no longer available. In situations of low availability due to demand surges, many people are trying to rent the same offers at once, and only one can succeed.
### Instance is taking too long to start
Startup time depends on the template and is usually under 5 minutes. If waiting over 20 minutes:
* Ensure you're using a recommended template
* Try a different machine
* Note: You're not charged while instances are loading
* With slow internet and large images, downloads can take an hour or more
# Instance Types
Source: https://docs.vast.ai/documentation/instances/choosing/instance-types
Understand Vast.ai instance types - On-demand, Reserved, and Interruptible. Learn how each type works, their differences, and when to use each.
Vast.ai offers three instance types with different priority levels and pricing models to match your workload requirements and budget.
## Overview
<CardGroup cols={3}>
<Card title="On-demand" icon="shield-check">
**High Priority**
Fixed pricing, guaranteed resources
</Card>
<Card title="Reserved" icon="piggy-bank">
**High Priority**
Discounted rates with pre-payment
</Card>
<Card title="Interruptible" icon="shuffle">
**Low Priority**
Lowest cost, may be paused
</Card>
</CardGroup>
In the create interface, you'll see a selector for "on-demand" or "interruptible". Once an instance is rented, you cannot change its type. However, you can convert on-demand instances to reserved for discounts.
## On-demand Instances
**Best for**: Production workloads, continuous training, time-sensitive tasks
On-demand instances provide:
* **Exclusive GPU control** with high priority
* **Guaranteed resources** for the contract duration
* **Fixed pricing** set by the host
* **Maximum duration** shown on offer cards
* **Data persistence** even when stopped
### Key Considerations
* Check the maximum duration before renting (shown on offer cards)
* For long-running jobs (days/weeks), verify host reliability scores
* When contracts expire, hosts may renew or stop the instance
* Data remains accessible when instances are stopped
<Warning>
**Expired Instance Deletion**: Expired instances may be deleted 48 hours after expiration. Retrieve your data before then. Expired instances cannot restart while expired.
</Warning>
## Reserved Instances
**Best for**: Long-term projects, predictable workloads, cost optimization
Reserved instances are on-demand instances with pre-paid discounts:
* **Up to 50% discount** based on commitment length
* **Same high priority** as on-demand
* **Convert anytime** from existing on-demand instances
* **Credits locked** to the specific instance
* **Partial refunds** available if cancelled early
To create a reserved instance, first rent on-demand, then convert using the discount badge on your instance card.
<Info>
For detailed instructions on creating and managing reserved instances, see [Reserved Instances](/documentation/instances/choosing/reserved-instances).
</Info>
## Interruptible Instances
**Best for**: Batch processing, fault-tolerant workloads, development/testing
Interruptible instances use a bidding system:
* **Lowest cost** (often 50%+ cheaper than on-demand)
* **Bidding priority** - higher bids get priority
* **May be paused** if outbid or if on-demand requested
* **Data preserved** when paused but instance not functional
* **Resume automatically** when priority returns
### Working with Interruptible Instances
<Warning>
When using interruptible instances:
* **Save work frequently** to disk
* **Use cloud storage** for important outputs
* **Implement checkpointing** in your code
* **Expect interruptions** and plan accordingly
</Warning>
Priority rules:
1. On-demand instances always have highest priority
2. Among interruptible instances, highest bid wins
3. Paused instances resume when they regain priority
## Choosing the Right Type
| Use Case | Recommended Type | Why |
| --------------------- | ---------------- | -------------------------------------- |
| Production inference | On-demand | Need guaranteed availability |
| Multi-day training | Reserved | Long-term discount with reliability |
| Hyperparameter search | Interruptible | Can handle interruptions, cost matters |
| Data preprocessing | Interruptible | Can resume where left off |
| Time-critical jobs | On-demand | Cannot afford interruptions |
| Development/testing | Interruptible | Short sessions, cost-sensitive |
| Steady workloads | Reserved | Predictable usage, want discounts |
## Quick Reference
### Switching Between Types
* **On-demand → Reserved**: ✅ Yes, anytime via discount badge
* **On-demand → Interruptible**: ❌ No, must create new instance
* **Interruptible → On-demand**: ❌ No, must create new instance
* **Reserved → On-demand**: ⚠️ Lose remaining discount
### Priority Levels
1. **On-demand/Reserved**: High priority, never interrupted
2. **Interruptible (high bid)**: Runs when resources available
3. **Interruptible (low bid)**: Paused until higher bids complete
## Next Steps
* **Compare costs**: Check current [Pricing](/documentation/instances/pricing)
* **Get discounts**: Learn about [Reserved Instances](/documentation/instances/choosing/reserved-instances)
* **Start renting**: [Finding & Renting](/documentation/instances/choosing/find-and-rent)
# Overview
Source: https://docs.vast.ai/documentation/instances/choosing/overview
Learn the complete process of selecting and renting a GPU instance on Vast.ai, from choosing templates to configuring and launching.
Renting an instance on Vast.ai involves three main steps that work together to get you the exact computing environment you need.
## The Rental Process
<Steps>
<Step title="Choose Your Template">
Select or customize a Docker template that defines your software environment - PyTorch, TensorFlow, Stable Diffusion, or custom configurations.
</Step>
<Step title="Find Your GPU">
Search and filter through available offers to find GPUs that match your performance needs and budget.
</Step>
<Step title="Configure & Rent">
Set your disk size, review the offer details, and launch your instance.
</Step>
</Steps>
## What You'll Need to Decide
Before renting an instance, you'll make key decisions about:
* **Software Environment**: Which Docker image and launch mode (SSH, Jupyter, etc.)
* **Hardware Requirements**: GPU type, VRAM, CPU, and system RAM needed
* **Storage Size**: How much disk space (cannot be changed after creation)
* **Instance Type**: On-demand for reliability or interruptible for cost savings
* **Budget**: Maximum price you're willing to pay per hour
## Quick Start Path
For the fastest path to a running instance:
1. **Use a Recommended Template** - Pre-configured and tested
2. **Sort by Price** - Find the best deals quickly
3. **Check Reliability Score** - 95%+ for important work
4. **Start with On-demand** - Upgrade to reserved later if needed
## What's in This Section
* **[Instance Types](/documentation/instances/choosing/instance-types)** - Understand on-demand vs interruptible vs reserved options
* **[Choosing a Template](/documentation/instances/choosing/templates)** - Understanding and selecting templates
* **[Finding & Renting](/documentation/instances/choosing/find-and-rent)** - Search, filter, configure, and rent
* **[Reserved Instances](/documentation/instances/choosing/reserved-instances)** - Save up to 50% with prepayment
## Common Questions
### How long does it take to start an instance?
Usually under 5 minutes with recommended templates. Large custom images may take longer on first launch.
### Can I change my configuration later?
* **Template**: No, you need a new instance
* **Disk size**: No, fixed at creation
* **Instance type**: Can convert on-demand to reserved only
### What if the GPU I want isn't available?
Set up search alerts or try different regions. Availability changes frequently as a marketplace.

# Reserved Instances
Source: https://docs.vast.ai/documentation/instances/choosing/reserved-instances
Save up to 50% on GPU costs by pre-paying for reserved instances. Learn how to convert on-demand instances to reserved pricing.
Reserved instances allow you to get significant discounts (up to 50%) by pre-paying for GPU time. You can convert any on-demand instance to a reserved instance at any time.
## How Reserved Instances Work
You can **convert an on-demand instance into a reserved instance** with a lower hourly rate by pre-paying.
**Key points:**
* Convert any on-demand instance to reserved pricing
* Discounts up to 50% based on commitment length
* Pre-paid credits are locked to that specific instance
* Cannot migrate between hosts

1. **Add credits** to your account (if needed).
2. Create an instance, get the instance id. CLI:`vastai show instances`
3. Run the following command, where: **ID** is the id of instance to prepay for **AMOUNT** is amount of instance credit prepayment (default discount func of 0.2 for 1 month, 0.3 for 3 months)
```cli CLI theme={null}
vastai prepay instance ID AMOUNT
```
An example:
```cli CLI theme={null}
vastai prepay instance 24973511 50
prepaid for 0.546 months of instance 24973511 applying $50.0 credits for a discount of 3.5000000000000004%
```

## Important Considerations
* If you later change your mind, you can withdrawal only any fraction of the funds that remain after paying the difference between the on demand and discounted price over the current duration.
* If the machine fails the implicit or explicit Service Level Agreement and is deverified the full balance can be withdrawn without penalty.
* Reserved instances cannot migrate between different hosts.
<Warning>
**Important:** Every time you add credits, your discount is recalculated. Avoid adding small amounts mid-term — you could end up with a worse rate. For example: If you have a 3-month reservation and add 2 weeks of credit with only 2 weeks left, your discount could drop.
</Warning>
## Extending a Reserved Instance
You can extend your reservation at any time:

Same flow as above - via **Save** badge on instance card.
</Tab>
<Tab title="CLI">
More flexibility — deposit any amount you choose. For example:
```bash Bash theme={null}
vastai prepay instance 24973511 50
prepaid for 0.546 months of instance 24973511 applying $50.0 credits for a discount of 3.5000000000000004%
```
</Tab>
</Tabs>
## Refunds
You can cancel (destroy) a reserved / prepaid instance to get part of your deposit back. Refund = Remaining deposit **minus** total discount already received.
**Example:**
* On-demand: $1/hr → $720/month
* Reserved (1 month): \$576/month
* Cancel immediately → Refund = \$576
* Cancel after 15 days → Remaining = $288 → Refund = $216 (after discount penalty)
* Cancel at the end → Refund = \$0
You will see the refund on the Billing page -> Invoices table.

## Common Questions
### Can I switch an existing on-demand instance to reserved?
Yes, if there is an available discount. Go to the **Instances** page, click the **discount badge** on your instance card, choose a period, and confirm.
### Can I extend a reserved instance?
Yes — you can extend it anytime via the same discount badge in the Instances page, as long as the instance still has an active discount period. You can use the CLI for custom amounts.
### What happens if I cancel / delete a reserved instance early?
You'll receive a partial refund of your unused pre-paid balance, minus the total discount received so far. The refund amount will be displayed in the delete instance modal and will also appear on the Billing page after you delete the instance.

### What happens if I stop a reserved instance?
If you stop the instance, the GPU will be released like any other instance and may be rented by another user.
## Next Steps
* Learn about other [rental types](/documentation/instances/pricing#rental-types)
* Understand [billing basics](/documentation/reference/billing)
* View your [current instances](https://cloud.vast.ai/instances/)
# Choosing a Template
Source: https://docs.vast.ai/documentation/instances/choosing/templates
Select the right template for your Vast.ai instance. Templates define your Docker image, launch mode, and initialization settings.
## What are Templates?
Templates are saved configurations that define how your instance will be set up. Every instance on Vast.ai requires a template that specifies:
* **Docker image** - The base container environment
* **Launch mode** - How you'll connect (SSH, Jupyter, or Entrypoint)
* **Initialization** - Startup scripts and environment variables
* **Ports and networking** - Required network configurations
<Note>
For comprehensive template documentation including creating custom templates, see the main [Templates section](/documentation/templates/introduction).
</Note>
## Selecting a Template
When renting an instance, you must select a template first. You have three options:
### 1. Recommended Templates
Pre-configured templates for common use cases:
* **PyTorch** - Ready for deep learning with Jupyter
* **TensorFlow** - ML development environment
* **Stable Diffusion** - Image generation UIs
* **LLM Inference** - Text generation setups
* **Base Ubuntu** - Clean development environment
### 2. Your Recent Templates
Templates you've previously used or customized are saved for quick access.
### 3. Custom Templates
Create your own or modify existing templates to match your exact needs.
## Quick Template Selection
1. On the [search page](https://cloud.vast.ai/create/), look for the template selector in the upper left
2. Click "Change Template" to see available options
3. Select a template that matches your needs
4. The search will update to show compatible machines
<Tip>
Start with a recommended template and modify it rather than creating from scratch. This ensures compatibility and faster startup times.
</Tip>
## Launch Modes
Templates support three connection methods:
### SSH
* Terminal access via SSH
* Best for: Development, training scripts, command-line work
* Includes tmux session management
### Jupyter
* Web-based notebook interface
* Best for: Data science, experimentation, visualization
* Includes terminal access
### Entrypoint
* Runs Docker's native entrypoint
* Best for: Automated workloads, API servers, production deployments
* No automatic SSH/Jupyter setup
## Important Template Settings
### Docker Image
* Always specify a version tag (avoid "latest")
* Vast.ai base images (`vastai/pytorch`) start faster due to caching
* Custom images from Docker Hub supported
### On-start Script
* Runs after the container starts
* Use for installing additional packages
* Executes as bash commands
### Disk Space
* Set in the search interface (not the template)
* Cannot be changed after instance creation
* Default is 10GB - increase as needed
## Common Issues
### Template Compatibility
Not all templates work on all machines. If an instance fails to start:
* Try a recommended template
* Check Docker image availability
* Verify port requirements match machine capabilities
### Invalid Docker Image Path
If you get an error like "Unable to find image 'ubuntu20.04\_latest/ssh'":
* You have an invalid Docker image path
* Use proper format: `nvidia/cuda:12.0.1-devel-ubuntu20.04`
* Always include repository and tag
* Test locally: `docker pull <YOUR_IMAGE_PATH>`
* Use recommended templates to ensure valid paths
### Image Loading Time
* First launch can take 5-60 minutes depending on image size
* Vast.ai base images load faster (pre-cached on many machines)
* You're not charged during loading
### Can't Change Template on Existing Instance
Templates are recipes for new instances. Once an instance is created:
* Template changes only affect new instances
* To use a different template, create a new instance
* Transfer data if needed using [data movement tools](/documentation/instances/storage/data-movement)
## Next Steps
**Ready to customize?**
See the full [Templates documentation](/documentation/templates/introduction) for:
* [Creating custom templates](/documentation/templates/creating-templates)
* [Advanced configuration](/documentation/templates/advanced-setup)
* [Template settings reference](/documentation/templates/template-settings)
**Having issues?**
* Start with a recommended template
* Check the [Templates FAQ](/documentation/reference/faq/instances#templates)
* Review [troubleshooting guide](/documentation/reference/troubleshooting)
# Instance Portal
Source: https://docs.vast.ai/documentation/instances/connect/instance-portal
## What is the Instance Portal?
The Instance Portal is the first application you will see after clicking the 'Open' button to access an instance that has been loaded with a [Vast.ai Docker image](https://github.com/vast-ai/base-image/). Many of our recommended templates include the Instance Portal.
<Frame caption="Instance card interface shows the open button">

During this loading phase, a secure Cloudflare tunnel will be created for each of your instance's open ports and the browser will test whether these tunnel links are accessible.
The secure tunnel link will be formatted like this:
[https://four-randomly-selected-words.trycloudflare.com](https://four-randomly-selected-words.trycloudflare.com)
When the secure tunnel for port `1111` becomes accessible, the instance Portal will redirect to this link before revealing the full interface.
If it is taking too long for the tunnels to be ready, you will see the Instance Portal interface revealed at `http://ip_address:port_1111`
If you would like the default application URLs to be **https\://** rather than **http\://** you can add the following environment variable to your [account level environment variables](https://cloud.vast.ai/account/):

If you set this variable, it is important to add the Vast.ai Jupyter certificate to your local system to avoid browser warnings. See [this page](/documentation/instances/jupyter#1SmCz) for more information about installing the certificate.
## Landing Page
The instance Portal has a simple interface to help you access other web applications that may be running in the instance. See the configuration section of this document for further details on application startup.

The large blue 'Launch Application' buttons will open your running applications in a new browser tab. &#x20;
If a secure tunnel is available, the button will open the 'trycloudflare.com' link. If a tunnel is not yet available then the button will open the direct IP address link.
In both cases, a secure token is appended to the link to prevent unauthorised access to your applications.
You can also click the 'Advanced Connection Options' link to see all available connection methods.

Use this interface to create links to applications you have started after configuring your instance. For example:
If you started an instance but later decide that you want to install some new software that listens on port `7860`, it will not be available directly if you did not configure the port when creating or editing the template.
Simply enter `http://localhost:7860` in the top input box and click the blue 'Create New Tunnel' button. A tunnel will be created for this port. It may take a moment to be available after creation.&#x20;
You can use the 'Manage' buttons to stop existing tunnels or to refresh them if you want a new URL.
If you would like to link your own domain name to the instance then please see 'Named Tunnels' in the configuration section of this document.
## Instance Logs Page
The logs page will show a live stream of entries added to any `.log` files in the `/var/log/portal/` directory.
Use the 'Copy Logs' button to copy the currently displayed logging output to your clipboard. You can also use the 'Download Logs' button to download a zip file containing all files and directories in the `/var/log/` directory of your instance.

## Configuration
Initial configuration of the Instance Portal is via the `PORTAL_CONFIG` enviroment variable. The default value looks like this:
```bash Bash theme={null}
localhost:1111:11111:/:Instance Portal|localhost:8080:18080:/:Jupyter|localhost:8080:8080:/terminals/1:Jupyter Terminal|localhost:8384:18384:/:Syncthing|localhost:6006:16006:/:Tensorboard
```
Each application is separated by a pipe (`|`) character, and each application option is separated by a colon (`:`)&#x20;
For each application, we provide the following configuration options
* Interface to bind the application (currently always `localhost`)
* External port to proxy the application. This must have been added to the template. Eg. `-p 1111:1111`)
* Internal port where the running application will be bound
* URL path for links to open (often `/`)
* Application Name
Where the external port and internal port **are not equal**, a reverse proxy (Caddy) will make your application available on the external port.
Where the external port and internal port **are equal** the application will not be proxied to the external port but secure tunnel application links will be created.
### In Place Configuration
On first boot the configuration variable will be processed and is used to create the configuration file `/etc/portal.yaml`
You can edit this file in a running instance to add or remove applications from the interface.
Any applications you have added after the instance has started will not initially be reachable so you will need to reboot the instance.
### Disable Default Applictions
The startup scripts we use for the default applications we provide will read this configuration and will not start if they are not specified in the configuration file.
### Named Tunnels
While the default behavior of the Instance Portal is to create 'quick' tunnels with a randomly assigned subdomain of 'trycloudflare.com', it is also possible to assign a pre-configured subdomain of your own domain name.
To do this you will need a free [Cloudflare Zero Trust](https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/) account and a domain name linked to that account.
Here's an example of how your tunnel configuration might look in the Cloudflare dashboard:

Once you have created your named tunnel, you can link it to your instance by providing the token associated with your tunnel as the value of environment variable `CF_TUNNEL_TOKEN`. You can save this in the 'Environment Variables' section in your [account settings](https://cloud.vast.ai/account/) or directly in the template if you are saving it privately.
If the instance is already running you can provide then token in the `/etc/environment` file and reboot the instance.
Named tunnels are generally more reliable than quick tunnels and will provide consistent URLs you can use to access applications running in an instance.
When named tunnels are configured, the 'Launch Application' button will direct to the named tunnel rather than the quick tunnel.
**Important:&#x20;**&#x55;sing the same tunnel token for multiple running instances is not possible and will cause broken links. If you need several instances then you will need a separate tunnel token for each of them.
# Jupyter
Source: https://docs.vast.ai/documentation/instances/connect/jupyter
Run Jupyter on Vast.ai with proxy or direct HTTPS. Learn setup, TLS certificate installation, and secure connections for smooth AI/ML development.
Jupyter is an interactive notebook interface that is very popular for AI/ML development using Python. Using Jupyter, you can connect to an interface in your browser and open any notebook that you can download as a .ipynb file.
We recommend this launch mode to start. We also recommend this launch mode over trying to run Google Colab with Vast. While Google Colab has a way to connect to a "local runtime", running Jupyter directly is more robust and less error prone if connections drop or the browser window is closed.
By default Jupyter instances use a proxy server. This is a simple setup that works on machines with or without open ports. The only downside is it can be slower to upload/download large files.
## Jupyter direct HTTPS launch mode
When selecting Jupyter there is a check box for "Jupyter direct HTTPS". This preferred option will establish a direct connection to the instance which is faster for uploading and downloading files from your local machine. Selecting this option will automatically filter out machines that do not have open ports, as they cannot establish a direct connection.
Jupyter uses a browser interface, so to get the direct HTTPS connection to work, you will need to install a certificate onto your operating system.
<Warning>
**WARNING**<br />
If you don't install the browser certificate, Windows and Linux will show a "Your connection is not private" Privacy error. It is annoying but you can click through by clicking "Advanced" and then proceed.
</Warning>
If you don't install the certificate on macOS, the OS might not let you open the Jupyter webpage.
## Installing the TLS certificate
Start by downloading the certificate [here](https://console.vast.ai/static/jvastai_root.cer). Then follow the directions for your operating system.
In most operating systems, double clicking on the certificate will start an installation wizard. You can also access the correct settings by clicking on the appropriate security settings in your browser.
### Chrome on Windows
1. Open your Chrome security settings by clicking on the three dot menu in the upper right. Then click Settings. Then click Privacy and security on the left hand navigation. From that menu, select Security.
2. Click on "Manage device certificates"
3. Click Next and then click Import and find the downloaded [jvastai\_root.cer](https://console.vast.ai/static/jvastai_root.cer) file.
4. Click "Place all certificates in the following store" and then use the browse button. Click on the **Trusted Root Certification Authorities** folder.

# Networking & Ports
Source: https://docs.vast.ai/documentation/instances/connect/networking
Understand how Vast.ai handles networking, port mapping, and environment variables for Docker instances.
## How Networking Works
Vast.ai docker instances have full internet access, but generally do not have unique IP addresses. Instances can have public open ports, but as IP addresses are shared across machines/instances the public external ports are partitioned somewhat randomly.
In essence each docker instance gets a fraction of a public IP address based on a subset of ports. Each open internal port (such as 22 or 8080 etc) is mapped to a *random* external port on the machine's (usually shared) public IP address.
Selecting the ssh launch mode will open and use port 22 internal by default, whereas jupyter will open and use port 8080 (in addition to 22 for ssh).
## Opening Custom Ports
There are several ways to open additional application ports:
<Note>
There is currently a limit of 64 total open ports per container/instance.
</Note>
### Using Docker Options
You can open custom ports for any docker image using -p arguments in the docker create/run options box in the image config editor pop-up menu.
To open ports 8081 (tcp) and 8082 udp, use something like this:
```text Text theme={null}
-p 8081:8081 -p 8082:8082/udp
```
This will result in additional arguments to docker create/run to expose those internal ports, which will be mapped to random external ports.
Any ports exposed in these docker options are in addition to:
* Ports exposed through EXPOSE commands in the docker image
* Ports 22 or 8080 which may be opened automatically for SSH or Jupyter
### Using EXPOSE in Dockerfile
Any EXPOSE commands in your docker image will be automatically mapped to port requests.
## Finding Your Mapped Ports
After the instance has loaded, you can find the corresponding external public IP by opening the IP Port Info pop-up (button on top of the instance) and then looking for the external port which maps to your internal port.
It will have a format of PUBLIC\_IP -> INTERNAL\_PORT. For example:
```text Text theme={null}
65.130.162.74:33526 -> 8081/tcp
```
In this case, the public IP 65.130.162.74:33526 can be used to access anything you run on port 8081 inside the instance.
## Testing Your Ports
We strongly recommend you test your port mapping. You can quickly test your port mapping with a simple command to start a minimal web server inside the instance:
```text Text theme={null}
python -m http.server 8081
```
Which you would then access in this example by loading 65.130.162.74:33526 in your web browser. This should open a file directory.
## Identity Ports
In some cases you may need an identity port map like 32001:32001 where external and internal ports are the same.
For this just use an out-of-range port above 70000:
```text Text theme={null}
-p 70000:70000 -p 70001:70001
```
These out of range requests will map to random external ports and matching internal ports.
You can then find the resulting mapped port with the appropriate env variables like: `$VAST_TCP_PORT_70000`
## Port Environment Variables
Our system predefines environment variables for port mappings that you can use:
### Default Ports
* **VAST\_TCP\_PORT\_22**: The external public TCP port that maps to internal port 22 (ssh)
* **VAST\_TCP\_PORT\_8080**: The external public TCP port that maps to internal port 8080 (jupyter)
### Custom Ports
For each internal TCP port request:
* **VAST\_TCP\_PORT\_X**: The external public TCP port that maps to internal port X
For each internal UDP port request:
* **VAST\_UDP\_PORT\_X**: The external public UDP port that maps to internal port X
## Special Environment Variables for UI
You can use special environment variables to control the Vast.ai interface:
### OPEN\_BUTTON\_PORT
Set this to map the open button on the instance panel to a specific (external) port corresponding to the specified internal port.
```text Text theme={null}
-e OPEN_BUTTON_PORT=7860
```
This will map the open button to whatever external port maps to internal port 7860.
### JUPYTER\_PORT
Use this to control the jupyter button. Set this to your internal jupyter port and the UI will map the jupyter button to open jupyter on the corresponding IP in a new tab.
```text Text theme={null}
-e JUPYTER_PORT=8081
```
This will map the jupyter button to whatever external port maps to internal port 8081.
### JUPYTER\_TOKEN
Use this to control the jupyter button. Set this to your jupyter token and the UI will map the jupyter button to open jupyter using the corresponding JUPYTER\_TOKEN in a new tab.
```text Text theme={null}
-e JUPYTER_TOKEN=TOKEN
```
This will use TOKEN as a value of your jupyter Token.
## Docker Create Options
You can currently set 3 types of docker create/run options in the GUI and CLI:
1. **Environment variables**: `-e JUPYTER_DIR=/ -e TEST=OK`
2. **Hostname**: `-h billybob`
3. **Ports**: `-p 8081:8081 -p 8082:8082/udp -p 70000:70000`
## Best Practices
1. **Test your ports**: Always verify port mappings work after instance creation
2. **Use identity ports sparingly**: Only when absolutely necessary (ports above 70000)
3. **Document your port usage**: Keep track of which services use which ports
4. **Check the limit**: Remember the 64 port limit per instance
5. **Use environment variables**: Leverage predefined port variables in your scripts
# Overview
Source: https://docs.vast.ai/documentation/instances/connect/overview
Learn about Vast.ai connection methods—SSH, Jupyter, and Entrypoint—and how each controls instance access and workflow.
We currently support 3 launch modes: entrypoint, ssh, and jupyter.
## Entrypoint
For this launch mode we simply run a docker container from your specified image as is.
The docker image entrypoint is the main run process, which you can override in the GUI or CLI (--entrypoint).
You can also pass arguments to your entrypoint in the GUI or CLI (--args).
Entrypoint launch mode is suitable for GPU worker instances which receive tasks from your webserver.
As ssh/jupyter access is not provided, your docker image is responsible for setting up any such connections as needed.
## SSH
For this launch option we setup an ssh connection using proxy and or direct connections where appropriate (mapping to port 22 internal).
If the machine supports open ports our system will try to setup both a direct ssh connection and a backup proxy connection.
This is mostly automatic under the hood, but it does require that your docker image is compatible with typical ssh daemon setup.
With the SSH launch option your docker image entrypoint is not called as we must override it.
Instead we allow you to specify an onstart script which is called as part of the new entrypoint.
So if you are using making a template from an existing docker image, you typically will want to find its entrypoint command and move that to the onstart.
More information on [SSH/SCP](/documentation/instances/connect/ssh)
## Jupyter
For this launch option we setup a jupyter using a proxy and or direct connections where appropriate (mapping to port 8080 internal).
If the machine supports open ports our system will try to setup a direct jupyter connection with a custom HTTPS certificate.
This is mostly automatic under the hood, but it does require that your docker image is compatible with typical jupyter setup.
With the Jupyter launch option your docker image entrypoint is not called as we must override it.
Instead we allow you to specify an onstart script which is called as part of the new entrypoint.
So if you are using making a template from an existing docker image, you typically will want to find its entrypoint command and move that to the onstart.

# SSH Connection
Source: https://docs.vast.ai/documentation/instances/connect/ssh
Learn how to securely connect to Vast.ai instances using SSH. Generate keys, establish connections, use port forwarding, and integrate with VS Code.
## About SSH
**SSH (Secure Shell)** is a protocol for safely connecting to remote servers. It encrypts your connection so you can:
* Log in securely
* Run commands remotely
* Transfer files without exposing your data
<Note>
Vast.ai instances are configured to accept keys only - Password authentication is disabled for improved security.
</Note>
## Quick start: Generate and add your SSH key to your Vast account
<Tabs>
<Tab title="Terminal">
**1. Generate a SSH key pair in your terminal**
<CodeGroup>
```bash Bash theme={null}
ssh-keygen -t ed25519 -C "your_email@example.com"
```
```powershell PowerShell theme={null}
ssh-keygen -t ed25519 -C "your_email@example.com"
```
</CodeGroup>
1. Creates two files (by default in \~/.ssh/):
* id\_ed25519 → your **private key** (keep safe, never share).
* id\_ed25519.pub → your **public key** (safe to share, add to servers).
2. -C "[your\_email@example.com](mailto:your_email@example.com)" is optional. Whatever you put there is stored as a comment in the public key file (e.g., id\_ed25519.pub). It's just for identification (helpful if you use multiple keys), not for security.
<Note>
When you run ssh-keygen -t ed25519 in **Windows PowerShell**, the keys are created in your Windows user profile folder:
`C:\Users\<YourUsername>\.ssh\`
</Note>
**2. Copy your public key.**
<CodeGroup>
```bash Bash theme={null}
# Print the public key
cat ~/.ssh/id_ed25519.pub
ssh-ed25519 AAAAC3NzaC1lZ9DdI1NTE5AAAAIHWGYlMT8CxcILI/i3DsRvX74HNChkm4JSNFu0wmcv0a
```
```powershell PowerShell theme={null}
# Print the public key
Get-Content $env:USERPROFILE\.ssh\id_ed25519.pub

### Direct vs Proxy Connections
Vast offers both proxy (default) and direct connection methods for SSH:
* **Proxy SSH**: Works on all machines, slower for data transfer, uses Vast proxy server
* **Direct SSH**: Requires machines with open ports, faster and more reliable, preferred method
## Tmux
We connect you to a tmux session by default for reliability and to prevent unintentional termination of foreground processes. You can create a new bash terminal window with `ctrl+b` + `c`. Cycle through your windows with `ctrl+b` + `n`
There is an excellent guide for getting to grips with tmux at [https://tmuxcheatsheet.com](https://tmuxcheatsheet.com/)
If, however, you would prefer to disable TMUX, you can apply the following either in a terminal or from your template's on-start section.
```text Text theme={null}
touch ~/.no_auto_tmux
```
## SSH Local Port Forwarding
An often overlooked feature of SSH is its ability to forward local ports to another machine. When you access a server remotely over SSH, you can make ports from the remote machine available as if they were listening on your own device. This is a secure alternative to opening ports on the public interface as all data is transported over the SSH connection.
```bash Bash theme={null}
ssh -p 1234 root@180.123.123.123 -L 8080:localhost:8080 -L 5000:localhost:5000
```
This SSH command connects to the remote instance and sets up **local port forwarding** (SSH tunneling):
**Connection details:**
* Connects to IP 180.123.123.123 as user root
* Uses port 1234 instead of the default SSH port 22
**Port forwarding (the key part):**
* `-L 8080:localhost:8080` - Creates a tunnel so when you access localhost:8080 on your local machine, it forwards to port `8080` on the remote server
* `-L 5000:localhost:5000` - Same thing for port `5000`
You can repeat the `-L` arguments to forward as many ports as you need.
**What this means:** After connecting, you can open your web browser and go to [https://localhost:8080](https://localhost:8080) or [http://localhost:5000](http://localhost:5000) on your local computer, and you'll actually be accessing services running on those ports on the remote server. It's like creating secure "tunnels" through the SSH connection to reach applications on the remote machine that might not be directly accessible from the internet.
## SSH Alternative - Jupyter Terminal
As a simple alternative to SSH, you might like to consider Jupyter Terminal instead. All instances started in Jupyter launch mode will have this enabled. It is a very straightforward web-based terminal with session persistence. It's great for a quick CLI session.
Access the terminal from the SSH connections interface.

## Troubleshooting
### Permission Denied (publickey)
If you get this error when trying to SSH:
1. Ensure your SSH key is added to your [Vast account](https://cloud.vast.ai/manage-keys/)
2. Verify you're using the correct private key
3. Check key file permissions: `chmod 600 ~/.ssh/id_ed25519`
4. Use `-vv` flag for detailed debug info: `ssh -vv -p PORT root@IP`
### SSH Key Changes
* New account keys only apply to NEW instances created after adding the key
* Existing instances keep their original keys (won't get new keys automatically)
* For VM instances, changing keys requires recreating the VM
* To add keys to existing instances, use the instance-specific SSH interface
### General Connection Issues
You can often determine the exact cause of a connection failure by using the -vv arguments with ssh to get more information.
Common reasons include:
* Using the wrong private key
* Incorrect permissions for your private key
* Public key not added to instance or account
* Connecting to the wrong port
## SCP & SFTP File Transfer
Both **SCP** (Secure Copy Protocol) and **SFTP** (SSH File Transfer Protocol) are tools for securely transferring files that piggyback on the SSH protocol. They use the same authentication and encryption as SSH.
### SCP (Secure Copy Protocol)
* **What it is:** Simple, command-line tool for copying files between local and remote machines
* **Best for:** Quick, one-time file transfers
* **Syntax:** `scp -P <port> source destination`
**Examples:**
```bash Bash theme={null}
# Copy file TO instance
scp -P <ssh_port> my_file.txt root@<instance_ip>:/workspace/
# Copy file FROM remote server
scp -P <ssh_port> root@<instance_ip>:/workspace/my_file.txt ./
# Copy entire directory
scp -P <ssh_port> -r myfolder/ root@<instance_ip>:/workspace/
```
### SFTP (SSH File Transfer Protocol)
* **What it is:** Interactive file transfer program with a full command set
* **Best for:** Managing files, browsing directories, multiple operations
* **Usage:** CLI or GUI tools available
**Example:**
```bash Bash theme={null}
# Establish connection
sftp -P <ssh_port> root@<instance_ip>
Welcome to vast.ai. If authentication fails, try again after a few seconds, and double check your ssh key.
Have fun!
Connected to 79.116.73.220.
sftp> ls
hasbooted onstart.sh
```
<Note>
Note that both scp and sftp take the `-P` argument in uppercase. This differs from the ssh command which uses lowercase.
</Note>
## VS Code Integration
Once you have your ssh keys set up, connecting to VS Code is quite straightforward. We will cover the basics here.
### Install the Remote SSH extension
You will need to add the remote extension named 'Remote - SSH'.

## GUI Setup Guide (Windows)
Several GUI tools are available to help with SSH connectivity. While it is often most straightforward to use the terminal we will cover some of the popular options here.
For each application we will assume the following:
* IP address: 142.114.29.158
* Port: 46230
* Username: root
To find your own connection details you can click the SSH button on your instance card.

### PuTTY
[PuTTY](https://www.chiark.greenend.org.uk/~sgtatham/putty/) consists of two important components - PuTTY for making connections and PuTTYGen for creating SSH keys.
First, we will generate a public and private key pair. PuTTy uses its own `.ppk` private key type.
Open PuTTYGen and click the 'Generate' button. You will be asked to move your mouse around until the green bar is full.

Once the key generation has completed, save both your public and private key somewhere safe such as in your Documents folder. Optionally you can enter a passphrase for your private key for added security.
Next, copy the full public key to the clipboard and add it to your account at [https://cloud.vast.ai/manage-keys/](https://cloud.vast.ai/manage-keys/)
Any keys stored at the account level will automatically be added to new instances as they are created. If you have an existing instance you can add keys to it from the instance card.

PuTTY has many additional features to explore. Find the full documentation [here.](https://www.chiark.greenend.org.uk/~sgtatham/putty/docs.html)
### MobaXterm
First, we need to create a public and private key pair. MobaXterm uses puTTY style `.ppk` keys.
Open the application and navigate to Tools -> MobaKeyGen (SSH Key Generator)

Once the key generation has completed, save both your public and private key somewhere safe such as in your Documents folder. Optionally you can enter a passphrase for your private key for added security.
Next, copy the full public key to the clipboard and add it to your account at [https://cloud.vast.ai/manage-keys/](https://cloud.vast.ai/manage-keys/)
Any keys stored at the account level will automatically be added to new instances as they are created. If you have an existing instance you can add keys to it from the instance card.

### Other GUI Clients
Many GUI clients are available for Windows and other operating systems, and although it is not possible to cover all of these here, the key things to remember when setting up are:
* Create a public and private key pair
* Add the public key to your vast account and any running instances
* Keep the private key safe
* Ensure you are connecting to the correct IP address and port as user `root`
# Managing Instances

Learn how to manage running instances - start, stop, destroy, monitor status, and handle common operational tasks.
## Overview
The Instances page ([cloud.vast.ai/instances](https://cloud.vast.ai/instances)) is your central hub for managing rented instances. From here you can:
* View instance status and information
* Start, stop, and destroy instances
* Access connection details
* Monitor resource usage
* Transfer data between instances

When restarting a stopped instance:
1. Instance enters `SCHEDULING` status
2. Waits for GPU availability
3. If stuck >30 seconds, GPU likely rented by another user
4. Cancel scheduling by clicking stop again
5. Consider creating new instance if GPU unavailable

## Troubleshooting Instance States
### Instance Stuck on "Loading"
* Normal for 30 seconds with cached images
* Can take hours with slow internet/large images
* Not charged during loading
* Try machines with faster internet
### Instance Stuck on "Scheduling"
When stopped instances try to restart:
* GPU may be reassigned to other users
* High-priority jobs block restart
* May wait indefinitely for GPU availability
* Consider copying data to new instance
### Instance Stuck on "Connecting"
* Port configuration may be broken
* Report the machine
* Try different machine
### Machine Shows "Offline"
* Lost connection to Vast servers
* Often internet/power issues
* Host notified automatically
* May be maintenance or unforeseen problems
## Important Considerations
### Data Persistence
* **Stopped instances**: Data preserved, storage charges continue
* **Destroyed instances**: All data permanently deleted
* **Before destroying**: Copy important data or sync to cloud
### Contract Expiration
<Warning>
Expired instances may be deleted 48 hours after expiration. Expired instances cannot restart. Retrieve your data promptly.
</Warning>
### Security
* Hosts can technically access files on their machines
* For sensitive data, use verified datacenters
* Implement encryption for critical data
### IP Addresses
Some instances have dynamic IPs that may change. Check IP type via the IP button on instance card. For static IPs, filter by "Static IP Address" when searching.
## Common Questions
### Can I run Docker inside my instance?
No, instances are already Docker containers. Docker-in-Docker is not supported.
### Do I pay for "Loading" instances?
No, you're not charged while instances show "Loading" status.
### Can I view past instances?
No, destroyed instances cannot be viewed. Recent template history is preserved for configuration reference.
### Why is my machine location showing only ", US"?
This means geolocation couldn't determine the state. It's not an indication of reliability.
### Can I run VMs or bare metal?
Currently only Docker containers are supported. VM and bare-metal options planned for future.

# Instances Overview
Source: https://docs.vast.ai/documentation/instances/overview
Instances are Docker containers that give you exclusive GPU access for training, inference, and development. Pay by the second, connect via SSH or Jupyter.
## What Are Instances?
Instances are containerized environments where you rent dedicated GPUs from Vast.ai's marketplace. Each instance:
* Provides exclusive GPU access (never shared between users)
* Runs your choice of Docker image
* Includes proportional CPU, RAM, and storage
* Connects via SSH, Jupyter, or custom entrypoint
* Bills by the second for actual usage

# Pricing
Source: https://docs.vast.ai/documentation/instances/pricing
Understand Vast.ai's marketplace pricing model, rental types, reserved discounts, and costs for GPU instances.
<Tip>
Vast.ai operates as a marketplace, connecting users with GPU providers worldwide. This means prices vary based on supply and demand, giving you access to competitive rates for GPU computing.
</Tip>
## How Vast.ai Pricing Works
Unlike traditional cloud providers with fixed pricing, Vast.ai uses a **marketplace model** where hosts set their own prices. This creates competitive rates without static price quotes—the market determines pricing in real-time.
You can easily check current market rates:
* **Web**: [Dashboard](https://cloud.vast.ai/create/) shows real-time prices
* **CLI**: Use `vastai search offers` to query prices programmatically (see [CLI Commands](/cli/commands#search-offers))
* **API**: Query programmatically via the [search offers endpoint](/api-reference/introduction)
<Info>
**Serverless Pricing**: Vast Serverless auto-scales instances with no separate pricing tier—you pay only for the underlying instance costs (compute, storage, bandwidth) with no additional fees. See [Serverless Pricing](/documentation/serverless/pricing) for details.
</Info>
### Key Pricing Principles
* **Market-driven rates**: Prices fluctuate based on real-time supply and demand
* **Combined pricing**: Your total cost includes a combination of GPU compute, storage, and bandwidth charges
* **Pay for what you use**: Billed by the second for actual usage
* **Service level pricing**: Costs vary based on dedicated or interruptible access and term length
## What does Vast cost compared to other providers?
Vast typically delivers more competitive pricing than traditional cloud providers. The marketplace model creates natural price competition—hosts compete for your business rather than locking you into fixed rates.
Key advantages:
* Direct competition between hosts drives rates lower
* Real-time supply and demand optimizes pricing
* No markup layered on top of host-set prices
* Global GPU supply improves availability and cost
Check current market rates in the [Dashboard](https://cloud.vast.ai/create/) or query programmatically via the [CLI](/cli/commands#search-offers) or [API](/api-reference/introduction).
## Cost Components
Your total rental cost includes three primary components:
### GPU Compute
Charged per second while your instance is running. Rates vary significantly based on:
* **GPU model**: High-end models (H100, A100) command premium rates
* **GPU quantity**: Multi-GPU configurations increase costs proportionally
* **Host reliability**: Higher reliability scores typically correlate with higher prices
* **Geographic location**: Regional supply and demand affects pricing
* **Market conditions**: Real-time marketplace dynamics influence rates
### Storage
Billed continuously while your instance exists, regardless of running state. Storage costs vary by host and are typically higher for stopped instances than running instances.
<Warning>
Storage charges continue even when instances are stopped. Delete instances completely to cease storage billing.
</Warning>
### Bandwidth
Data transfer costs vary by host and include both upload and download traffic. Charges apply per byte transferred. Review bandwidth rates during instance selection as these can significantly impact total costs for data-intensive workloads.
## Instance Types & Pricing
Vast.ai offers three instance types with different pricing models:
* **On-demand**: Fixed pricing, guaranteed resources (high priority)
* **Reserved**: Discounted rates with pre-payment (high priority)
* **Interruptible**: Lowest cost, may be paused (low priority)
Pricing varies by instance type, with interruptible instances often 50%+ cheaper than on-demand, and reserved instances offering up to 50% discount with commitment.
For detailed information about each instance type and when to use them, see [Instance Types](/documentation/instances/choosing/instance-types).
## Common Pricing Questions
### How do I find the cheapest GPUs?
Use the search filters on the [Dashboard](https://cloud.vast.ai/create/) to sort by price. Consider:
* Interruptible instances for non-critical workloads (often 50%+ cheaper)
* Lower reliability scores (may offer better rates)
* Different geographic regions
### Can I get a discount for long-term use?
Yes! Convert any on-demand instance to reserved pricing for up to 50% off. See [Reserved Instances](/documentation/instances/choosing/reserved-instances) for details.
### Why do prices vary so much?
Vast.ai is a marketplace where hosts set their own prices based on:
* Supply and demand in their region
* Their operating costs
* Machine specifications and reliability
* Competition from other hosts
## Billing Basics
Here are the essential billing concepts to understand:
* **Credits required upfront**: You must add credits to your account before starting any instances
* **Automatic instance suspension**: When your credit balance reaches zero, instances are automatically stopped but remain in your account
* **Ongoing storage charges**: You continue to be billed for storage on stopped instances until they are deleted
For complete billing details, see the [billing page](/documentation/reference/billing).

## Setup
### 1. Setting Up Cloud Storage Connections
Before creating backup jobs, you need to ensure you have a cloud storage connection set up in your Vast.ai account. You can view your existing connections using the vast-cli:
```text theme={null}
python3 vast.py show connections
ID NAME Cloud Type
19447 karthik_vast_ai_google_drive drive
```
If you don't have a connection yet, you'll need to set one up in [Vast.ai's Settings page ](/documentation/instances/cloud-sync)before proceeding with backup operations.
### 2. Understanding Backup Options
Vast.ai provides multiple approaches to schedule data backups:
* **Using Vast's job scheduling system via CLI** - Create hourly, daily, or weekly automated backup jobs
* **Using cron on your personal computer** - Schedule backups with custom timing from your local machine
Both approaches have their advantages depending on your workflow and requirements.
## Backup Methods
### 1. Using CLI for Scheduled Backups
The vast-cli tool allows you to create scheduled backup jobs with several timing options. The basic structure of a scheduled backup command includes these parameters:
```text theme={null}
--schedule SCHEDULE Values: HOURLY, DAILY, WEEKLY
--start_date START_DATE Start date in format 'YYYY-MM-DD HH:MM:SS PM' (UTC)
--end_date END_DATE End date in format 'YYYY-MM-DD HH:MM:SS PM' (UTC)
--day DAY Day of week (0-6, where 0=Sunday) or "*"
--hour HOUR Hour of day (0-23) or "*"
```
You can run this command to see more details about these parameters:
```text theme={null}
python3 vast.py cloud copy --help
```
Let's explore the different scheduling options:
To create a weekly backup job that runs every Saturday at 9 PM UTC:
```text theme={null}
python3 vast.py cloud copy --src /workspace --dst /backups/19015821_backups/ --instance 19015821 --connection 19447 --transfer "Instance To Cloud" --schedule WEEKLY --day 6 --hour 21
```
In this command:
* \--src /workspace specifies the source directory on your instance
* \--dst /backups/19015821\_backups/ is the destination folder in your cloud storage
* \--instance 19015821 is your instance's ID
* \--connection 19447 is your cloud storage connection ID
* \--day 6 represents Saturday (0=Sunday, 1=Monday, etc.)
* \--hour 21 represents 9 PM UTC (0=12am UTC, 1=1am UTC, etc.)
For daily backups at a specific hour (e.g., 9 PM UTC every day):
```text theme={null}
python3 vast.py cloud copy --src /workspace --dst /backups/19015821_backups/ --instance 19015821 --connection 19447 --transfer "Instance To Cloud" --schedule DAILY --day "*" --hour 21
```
The --day "\*" parameter indicates that the job should run every day.
For hourly backups that run every hour of every day:
```text theme={null}
python3 vast.py cloud copy --src /workspace --dst /backups/19015821_backups/ --instance 19015821 --connection 19447 --transfer "Instance To Cloud" --schedule HOURLY --day "*" --hour "*"
```
Setting both --day "\*" and --hour "\*" along with --schedule HOURLY makes the job run every hour.
To update your backup schedule, simply run the same command with the new schedule. The system will prompt you for confirmation, and upon acceptance, it will update the schedule accordingly.&#x20;
```text theme={null}
Existing scheduled job found. Do you want to update it (y|n)? y
add_scheduled_job update: success - Scheduling DAILY job to cloud copy from 1745599087.0 to 1746599887.0
```
### 2. Using Cron on Your Personal Linux Computer
If you prefer more granular control over your backup schedule, you can use cron on your local Linux or Mac computer. This approach allows for customized schedules beyond the hourly/daily/weekly options.
First, open your crontab file for editing:
```text theme={null}
crontab -e
```
Then, add a line that specifies your backup schedule. For example, to run a backup every 4 hours:
```text theme={null}
0 */4 * * * python3 vast.py cloud copy --src /workspace --dst /backups/19015821_backups/ --instance 19015821 --connection 19447 --transfer 'Instance To Cloud'
```
In this cron schedule:
* 0 represents the minute (0th minute of the hour)
* \*/4 means "every 4 hours"
* The three asterisks \* \* \* represent day of month, month, and day of week, indicating "every day"
## Viewing Scheduled Backup Jobs
To see all your currently scheduled backup jobs:
```text theme={null}
python3 vast.py show scheduled-jobs
```
Example output:
```bash Bash theme={null}
Scheduled Job ID Instance ID API Endpoint Start (Date/Time in UTC) End (Date/Time in UTC) Day of the Week Hour of the Day in UTC Minute of the Hour Frequency
1 19778412 /api/v0/commands/rclone/ 2025-04-24/23:38 2028-05-06/23:38 Everyday 4_PM 00 DAILY

* Runs daily at the same time
* Will continue running from Apr 24, 2025 until May 6, 2028
2. **Job 2**: A **WEEKLY** backup that runs on **Wednesdays at 10:00 AM UTC**&#x20;
* Runs only on Wednesdays at 10:00 AM UTC
* Short duration job (Apr 29 - May 9, 2025)
3. **Job 3**: A **HOURLY** backup that runs **every hour of every day**
* Runs every hour (1\_AM, 2\_AM, 3\_AM, etc.)
* Will continue running for a year
## Deleting Scheduled Backup Jobs
If you need to remove a scheduled backup job that you no longer want to run, you can use the delete scheduled-job command followed by the job ID:
```bash Bash theme={null}
python3 vast.py delete scheduled-job JOB_ID
```
For example:
```bash Bash theme={null}
python3 vast.py delete scheduled-job 4462309
```
This will completely remove the scheduled job from the system. When successful, you'll receive a confirmation message:
```bash Bash theme={null}
{'success': True, 'msg': 'Scheduled job 4462309 deleted successfully'}
```
### Find Job IDs to Delete
To find the ID of the job you want to delete, first run:
```bash Bash theme={null}
python3 vast.py show scheduled-jobs
```
You'll see output similar to:
```bash Bash theme={null}
Scheduled Job ID Instance ID API Endpoint Start (Date/Time) End (Date/Time) Day of the Week Hour of the Day Minute of the Hour Frequency
4462317 19281511 /api/v0/commands/rclone/ 2025-04-08/09:01 2028-06-08/18:48 Everyday 1_PM 33 DAILY
4462321 19489711 /api/v0/commands/rclone/ 2025-04-15/20:00 2025-04-19/20:00 Saturday 11_PM 00 WEEKLY
4462322 19490133 /api/v0/commands/rclone/ 2025-04-15/20:00 2025-04-19/20:00 Wednesday 8_PM 10 WEEKLY
```
The scheduled\_job\_id column in the output contains the IDs you'll need for deletion.
## Best Practices
### Choose the Right Backup Frequency
Consider these factors when determining how often to back up your data:
* How frequently your data changes
* The criticality of your data
* The cost of data loss
* The performance impact of backup operations
* The bandwidth costs of backing your data up in cloud storage
### Back Up Only What You Need
Be selective about what you back up to save time and storage costs:
* Focus on backing up only important data (models, results, custom code)
### Verify Your Backups
Periodically check that your backups are working correctly:
* Download a sample backup from cloud storage and verify its contents
* Check logs for any cloud copy failures
* Test the restoration process before you actually need it
* If contract is extended, update end\_date of scheduled job
## Conclusion
Setting up regular backups for your Vast.ai instances can be a valuable part of a robust workflow. By choosing the appropriate backup method and schedule, you can ensure that your valuable work remains safe and accessible regardless of instance lifecycle events.
Remember that the best backup system is one that you set up before you need it. Take time now to implement a backup strategy that meets your needs, and you can thank yourself later.

# Cloud Sync
Source: https://docs.vast.ai/documentation/instances/storage/cloud-sync
Learn how to connect Vast.ai instances with cloud storage providers like Google Drive, S3, Backblaze, and Dropbox for secure data sync.
<Warning>
**WARNING**<br />
Cloud Sync is only supported on Docker-based instances. Cloud Sync is not currently supported on VM-based instances (instances created using a vastai/kvm repository template)
</Warning>
Cloud Sync Integrations allow you to move data freely to and from instances on Vast.
<Note>
In order to move data from cloud providers to Vast instances you must provide certain credentials which will be temporarily moved onto your instance which is stored on a host machine. For this reason you should only use cloud integration options when using verified hosts that are datacenters. You can filters for these hosts using the command line interface or on the website instance creation page using the 'Secure Cloud' checkbox.
</Note>
## Google Drive
<Warning>
**WARNING**<br />
Note that Vast will connect at the account level. Therefore it is recommended for users to have a dedicated Google Drive for Vast use cases rather than using their personal account.
</Warning>
Prerequisites: Have an active Google Drive account
1. Navigate to your [account](https://cloud.vast.ai/account) page
2. On the bottom you should see a button that says Connect to Google Drive
3. Enter a name for your integration with Google Drive.
4. Submit the name, after which a new tab should open up asking if you would like to give Vast access to your Google Drive.
5. Once the verification prompt has been accepted, you will be redirected back to vast with your Google Drive fully integrated.
<Frame caption="Gdrive">
![Gdrive](https://vast.ai/uploads/gdrive.png)
</Frame>
You have now connected your Google Drive with Vast. This will allow you to move data to and from instances even while inactive.
## Amazon S3
Prerequisites: An active Amazon Web Services (AWS) account.
<Warning>
**WARNING**<br />
We do not recommend using an existing IAM user on Vast. Vast connects on a user level rather than an account level, so it's best to create a new IAM user with the intended authorization for the data you want to store on vast.ai servers.
</Warning>
1. Create a S3 Bucket in AWS
2. Create an IAM User and Grant Access to the S3 Bucket, we recommend you create a user with access to your specific bucket for this process rather than full access.
<Frame caption="Awss3">
![Awss3](https://vast.ai/uploads/awss3.png)
</Frame>
1. Once the user is created, click the user and go Security credentials.
2. Click Create access key, and enable for Command Line interface
3. Once the access key is created, you will be prompted with an Access Key, and a Secret access Key. This will be the information required to use your AWS user permissions on Vast.
4. Navigate to your [account](https://cloud.vast.ai/account) page
5. On the bottom you should see a button that says Connect to Amazon S3
6. Enter your credentials in the given fields, as well as a name for your integration with Amazon.
You have now connected an Amazon Web Services user with Vast. This will allow you to move files from services like Amazon S3 to and from instances on Vast.
## Backblaze
<Warning>
**WARNING**<br />
Note that Vast connects to cloud providers at the account level. Any bucket your application key has access to will be accessible with Vast. This can cause security concerns with some use cases that should be dealt with by creating a new application key used specifically for data you want to store on vast.ai servers.
</Warning>
1. Create a bucket in Backblaze. It should not matter if the bucket is private or public.
2. Go to Application Keys
3. Select Add a New Application Key
4. Grant access for Read and Write operations on the bucket of your choice
5. Note the keyId and the applicationKey that are returned to you. This is the data required for Vast.
6. Navigate to your [account](https://cloud.vast.ai/account) page
7. On the bottom you should see a button that says Connect to Backblaze
8. Enter your credentials in the given fields, as well as a name for your integration with Backblaze.
You have now connected your Backblaze account with Vast. This will allow you to move data to and from Instances easily.
## Dropbox
<Warning>
**WARNING**<br />
Note that Vast will connect at the account level. Therefore it is recommended for users to have dedicated dropbox accounts for Vast use cases rather than using their personal account.
</Warning>
1. Navigate to your [account](https://cloud.vast.ai/account) page
2. On the bottom you should see a button that says Connect to Dropbox
3. Enter a name for your integration with Dropbox.
4. Submit the name, after which a new tab should open up asking if you would like to give Vast access to your Dropbox.
5. Once the verification prompt has been accepted, you will be redirected back to vast with dropbox fully integrated.
You have now connected your Dropbox account with Vast. This will allow you to move data to and from Instances seamlessly.
# Data Movement
Source: https://docs.vast.ai/documentation/instances/storage/data-movement
Learn how to move data on Vast.ai using cloud sync, instance-to-instance transfers, CLI copy, VM migration, scp, and other efficient methods.
Vast.ai currently supports several built-in mechanisms to copy data to/from instance storage (in addition to all of the standard linux/unix options available inside the instance):
For docker based instances:
1. Instance\<->Instance and Instance\<->Local copy using the `vastai copy` CLI command
2. Instance\<->Instance copy in the GUI instance control panel or `vastai copy` CLI command
3. Instance\<->Cloud copy using the GUI instance control panel or `vastai cloud copy` CLI command
For VM instances:
1. Instance\<->Instance migration through the `vastai vm copy` CLI command or the GUI instance control panel
These are in addition to standard ssh based copy protocols such as scp or sftp which you can run over ssh, built in jupyter http copy, and any other linux tools you can run inside the instance yourself (rclone, rsync, bittorent, [insync](https://www.insynchq.com/headless-for-linux) etc).
The 3 built-in methods discussed here are unique in that they offer ways to copy data to/from a *stopped instance*, with some constraints. Copying data between instances accrues internet bandwidth usage charges (with prices varying across providers), unless the copy is between two instances on the same machine or local network, in which case there is no bandwidth charge.
## Instance\<->Cloud copy (cloud sync)
The cloud sync feature allows you to copy data to/from instance local storage and several cloud storage providers (S3, gdrive, backblaze, etc) - even when the instance is stopped.
### Using the GUI
Vast currently supports Dropbox, Amazon S3 and Backblaze cloud storage providers.
First you will need to connect to the cloud provider on the [account page](https://cloud.vast.ai/account/) and then use the cloud copy button on the instance to start the copy operation.
<Frame caption="Cloud Copy">
![Cloud Copy](https://vast.ai/uploads/cloud-copy.JPG)
</Frame>
See [Cloud Sync](/documentation/instances/cloud-sync) for more details.
### Using the CLI
You can also access this feature using the `vastai cloud copy` [CLI command](/cli/commands#cloud-copy).
## Instance \<-> Instance copy
Instance to instance copy allows moving data directly between the local storage of two instances.
If the two instances are on the same machine or the same local network (same provider and location) then the copy can run at faster local network storage speeds and there is no internet transit cost.
### Using the GUI
You can use the copy buttons to copy data between two instances. Instances can be stopped/inactive. See complete [Constraints](./#constraints) below.
Click the copy button on the source instance and then on the destination instance to bring up the copy dialogue. For docker-based instances you will see the following folder dialogue.
<Frame caption="Itoicopy">
![Itoicopy](https://vast.ai/uploads/itoicopy.gif)
</Frame>
Pick the folders where you want to copy to/from. Leave a '/' at the end of the source directory to copy all the files inside into the target directory, vs nesting a copy of the source dir into the target dir.
<Warning>
**WARNING**\\
You should not copy to /root or / as a destination directory, as this can mess
up the permissions on your instance ssh folder, breaking future copy
operations (as they use ssh authentication).
</Warning>
<Frame caption="Copy Modal">
![Copy Modal](https://vast.ai/uploads/copy-modal.JPG)
</Frame>
After clicking the copy button, give it 5-10 seconds to start. The status messages will display as the copy operation begins.
For VM based instances you will see a confirmation dialog instead; the copy will copy your entire source instance to the destination machine. The destination instance's disk will be replaced by the contents of the source instance.
### Using the CLI
You can also access this feature using the `vastai copy` [CLI command](/cli/commands#copy).
## CLI Copy Command
You can use the [CLI](/cli/get-started) copy command to copy from/to directories on a remote instance and your local machine, or to copy data between two remote instances.
The copy command uses rsync and is generally fast and efficient, subject to single link upload/download constraints.
The copy command supports multiple location formats:
* `[instance_id:]path` - Legacy format (still supported)
* `C.instance_id:path` - Container copy format
* `cloud_service:path` - Cloud service format
* `cloud_service.cloud_service_id:path` - Cloud service with ID
* `local:path` - Explicit local path
Examples:
```text Text theme={null}
vastai copy 6003036:/workspace/ 6003038:/workspace/
vastai copy C.11824:/data/test local:data/test
vastai copy local:data/test C.11824:/data/test
vastai copy drive:/folder/file.txt C.6003036:/workspace/
vastai copy s3.101:/data/ C.6003036:/workspace/
```
The first example copy syncs all files from the absolute directory '/workspace' on instance 6003036 to the directory '/workspace' on instance 6003038.
The second example copy syncs files from container 11824 to the local machine using structured syntax.
The third example copy syncs files from local to container 11824 using structured syntax.
The fourth example copy syncs files from Google Drive to an instance.
The fifth example copy syncs files from S3 bucket with id 101 to an instance.
## CLI Copy Command (VMs)
You can use the [CLI](/cli/get-started) vm copy command to copy your entire VM from one instance to another. The destination VM's disk will be replaced with the contents of the source machine.
Example:
```text Text theme={null}
vastai vm copy 1241241 1241245
```
This will transfer the contents of 1241241 to 1241245.
### Constraints
For VM-based instances, the destination instance must be stopped during the transfer.
<Warning>
**WARNING**\\
You should not copy to /root or / as a destination directory, as this can mess
up the permissions on your instance ssh folder, breaking future copy
operations (as they use ssh authentication).
</Warning>
### Performance
If your data is already stored in the cloud (S3, gdrive, etc) then you should naturally use the appropriate linux CLI or commands to download and upload data directly, or you could use the [cloud sync](/documentation/instances/cloud-sync) feature.
This generally will be one the fastest methods for moving large quantities of data, as it can fully saturate a large number of download links.
If you are using multiple instances with significant data movement requirements you will want to use high bandwidth cloud storage to avoid any single machine bottlenecks.
If you launched a Jupyter notebook instance, you can use its upload feature, but this has a file size limit and can be slow.
You can also use standard Linux tools like scp, ftp, rclone, or rsync to move data.
For moving code and smaller files scp is fast enough and convenient.
However, be warned that the default ssh connection uses a proxy and can be slow for large transfers (direct ssh recommended).
Instance to instance copy is generally as fast as other methods, and can be much faster (and cheaper) for moving data between instances on the same datacenter.
## SCP
If you launched an ssh instance, you can copy files using scp. The proxy ssh connection can be slow (in terms of latency and bandwidth).
Thus we recommend only using scp over the proxy ssh connection for smaller transfers (less than 1 GB).
For larger inbound transfers, using the direct ssh connection is recommended.
Downloading from a cloud data store using wget or curl can have much higher performance.
The relevant scp command syntax is:
```text Text theme={null}
scp -P PORT LOCAL_FILE root@IPADDR:/REMOTEDIR
```
The PORT and IPADDR fields must match those from the ssh command (note the use of -P for port instead of -p !). The "Connect" button on the instance will give you these fields in the form:
```text Text theme={null}
ssh -p PORT root@IPADDR -L 8080:localhost:8080
```
For example, if Connect gives you this:
```text Text theme={null}
ssh -p 7417 root@52.204.230.7 -L 8080:localhost:8080
```
You could use scp to upload a local file called "myfile.tar.gz" to a remote folder called "mydir" like so:
```text Text theme={null}
scp -P 7417 myfile.tar.gz root@52.204.230.7:/mydir
```
## Common Questions
### How do you recommend I move data from an existing instance?
The [cloud sync feature](/documentation/instances/cloud-sync) will allow you to move data to and from instances easily.
The main benefit is that you can move data around while the machine is inactive.
Currently, we support Google Drive, S3, Dropbox, and Backblaze
### Help, I want to move my data but I forgot what directory it's in!
For moving your data, by either using our Cloud Sync or Instance Copy features, you will need to define the path from where the data you are transferring is coming from and where it is to be put. If you don't remember where the data is you are trying to transfer, you can use our [CLI execute command](/cli/commands#execute) to access your instance when your instance access is limited.
### What if I don't remember the file names on my inactive instance, but I want to copy certain files?
Use the vast CLI, run the `execute` command to display the file tree. This will help you browse the available files and identify the names or paths you need. More about the execute command you can find [here](https://cloud.vast.ai/cli/).
```
vastai execute INSTANCE_ID 'ls -l'
```
### How I can free up disk space on an inactive instance?
When an instance is inactive (stopped, exited, cannot be started), you can still manage its file system and remove unneeded data using vast CLI. This is useful if you want to free up disk space without starting the instance.
Check disk usage:
```
vastai execute INSTANCE_ID 'du -d1 -h'
```
Delete unnecessary files:
```
vastai execute INSTANCE_ID 'rm file_name.txt'
```
# Storage Types
Source: https://docs.vast.ai/documentation/instances/storage/types
Understand the different storage options available on Vast.ai instances, including container storage and volumes.
## Storage Overview
Vast.ai provides two main types of storage for your instances:
1. **Container Storage** - Temporary storage within the Docker container
2. **Volumes** - Persistent local storage that can be attached to instances
## Container Storage
Container storage is the default storage allocated to every instance when it's created.
### Key Characteristics
* **Size is fixed at creation**: You must specify the disk size when creating the instance
* **Cannot be resized**: Once created, the allocation cannot be changed
* **Persists while instance exists**: Data remains even when instance is stopped
* **Deleted with instance**: All data is permanently lost when instance is destroyed
* **Charged continuously**: Storage costs apply even when instance is stopped
### Default Allocation
* Minimum: 10GB (default)
* Maximum: Varies by host machine capacity
* Set via disk size slider during instance creation
<Warning>
Storage charges continue even when instances are stopped. To stop storage billing, you must destroy the instance completely.
</Warning>
### Best Practices
1. **Estimate generously**: Better to have extra space than run out mid-task
2. **Monitor usage**: Check disk space regularly with `df -h`
3. **Clean up regularly**: Remove unnecessary files to free space
4. **Back up important data**: Container storage is lost when instance is destroyed
## Volumes
Volumes provide persistent storage that survives instance destruction and can be reattached to new instances.
### Key Features
* **Local only**: Tied to the physical machine where created
* **Persistent**: Survives instance destruction
* **Reattachable**: Can be mounted to new instances on same machine
* **Fixed size**: Cannot be resized after creation
* **Separate billing**: Charged independently from instances
### Volume Limitations
* Cannot migrate between different physical machines
* Can only attach to instances on the same host
* Must destroy attached instance before deleting volume
* Size must be specified at creation time
For detailed volume management, see [Volumes](/documentation/instances/storage/volumes).
## Storage Costs
Storage pricing varies by host and includes:
1. **Container storage**: Charged per GB while instance exists
2. **Volume storage**: Charged per GB while volume exists
3. **Different rates**: Stopped instances may have higher storage rates than running instances
## Data Persistence Strategy
### Temporary Work
Use container storage for:
* Temporary files
* Build artifacts
* Cache data
* Working datasets
### Important Data
Use volumes or cloud sync for:
* Trained models
* Datasets
* Code repositories
* Configuration files
### Backup Options
1. **Volumes**: For same-machine persistence
2. **Cloud Sync**: For off-machine backup (Google Drive, S3, etc.)
3. **Instance-to-instance copy**: Transfer between instances
4. **SCP/SFTP**: Download to local machine
## Common Questions
### Can I increase storage after instance creation?
No, container storage size is fixed at creation. You can:
* Create a new instance with more storage and [transfer your data](/documentation/instances/storage/data-movement)
* Attach a volume for additional space
* Use cloud storage for overflow
### What happens to my data when the instance stops?
* Container storage: Data persists, charges continue
* Volumes: Data persists, charges continue
* No data is lost when stopping instances
### How do I avoid storage charges?
* Destroy instances you're not using
* Delete unneeded volumes
* Transfer important data to local/cloud storage first
## Next Steps

# Volumes
Source: https://docs.vast.ai/documentation/instances/storage/volumes
The [**Storage**](https://cloud.vast.ai/storage/) page allows you to easily access and manage your **volumes -** storage that can be attached to your instances for data storage.
We currently provide **local volumes only**, meaning:
* A volume is physically tied to the machine it was created on.
* It can only be attached to instances running on the same physical machine.
* It cannot be moved or attached to instances on other machines.
<Note>
Volume size cannot be changed after creation, so be sure to choose the size carefully based on your expected storage needs.&#x20;
</Note>
## Creating a Volume in GUI
This guide will walk you through the process of creating a volume using a template in the GUI. You can create the volume during instance creation by using a template with volume settings enabled, or you can create a volume by using dropdown menu on the Search page.&#x20;
### **How to create a volume via Add volume dropdown menu on the Search page?**
1. Select a template then click on **Add volume** dropdown. You will see an option labeled **Local volume** with a + (plus) button next to it.

### Deleting volume
To delete a volume, the instance it is attached to must be **deleted first**. Deleting a volume that is currently **mounted to a running or stopped instance is not allowed**.
Delete a Volume:
1. Make sure the volume is **not attached** to any instance.
&#x20;If it is, **delete the instance** first from the Instances page.
2. Once the volume is detached, go to the **Storage** page.

4. Confirm the deletion. This action is **permanent** and cannot be undone.
<Warning>
Important: Deleting a volume will permanently remove all data stored in it. Make sure to back up any important data before proceeding.
</Warning>
### How to create an instance with existing volume?
If you already have a volume and want to launch a new instance using it, follow these steps:
1. Go to the **Storage** page and select the volume you want to use.
2. In the **Volume Info** section, you will see a button labeled **Rent instance using this volume**.
<img src="https://mintcdn.com/vastai-80aa3a82/1a9mKbP8zn3lYY0d/images/volumes-10.webp?fit=max&auto=format&n=1a9mKbP8zn3lYY0d&q=85&s=8c4db1caeb318e91efe1850d0fdcacfc" alt="Rent instance using this volume" data-og-width="1280" width="1280" data-og-height="884" height="884" data-path="images/volumes-10.webp" data-optimize="true" data-opv="3" srcset="https://mintcdn.com/vastai-80aa3a82/1a9mKbP8zn3lYY0d/images/volumes-10.webp?w=280&fit=max&auto=format&n=1a9mKbP8zn3lYY0d&q=85&s=ab654c1695400e43e38b41977f4ce40b 280w, https://mintcdn.com/vastai-80aa3a82/1a9mKbP8zn3lYY0d/images/volumes-10.webp?w=560&fit=max&auto=format&n=1a9mKbP8zn3lYY0d&q=85&s=ab9eb0a79d57f5da8a097bc265579e35 560w, https://mintcdn.com/vastai-80aa3a82/1a9mKbP8zn3lYY0d/images/volumes-10.webp?w=840&fit=max&auto=format&n=1a9mKbP8zn3lYY0d&q=85&s=f4c9d1deeb06f35fe2107d5a2680235f 840w, https://mintcdn.com/vastai-80aa3a82/1a9mKbP8zn3lYY0d/images/volumes-10.webp?w=1100&fit=max&auto=format&n=1a9mKbP8zn3lYY0d&q=85&s=5482e5891a57e783b772ae83145f2f99 1100w, https://mintcdn.com/vastai-80aa3a82/1a9mKbP8zn3lYY0d/images/volumes-10.webp?w=1650&fit=max&auto=format&n=1a9mKbP8zn3lYY0d&q=85&s=082666cb048688d73ed1379d6e4e7620 1650w, https://mintcdn.com/vastai-80aa3a82/1a9mKbP8zn3lYY0d/images/volumes-10.webp?w=2500&fit=max&auto=format&n=1a9mKbP8zn3lYY0d&q=85&s=6ca65ed70090abc4332bcf61bc6fff35 2500w" />
3. Click this button. You will be redirected to the **Search Page**, where available offers are automatically filtered to match the **same machine** where the volume is located.
4. Select your preferred offer and proceed to launch the instance.
&#x20;The selected volume will be automatically attached to the instance upon creation.
## Creating a Volume in CLI
To create a volume, you can use the vast CLI. See our [CLI documentation](https://cloud.vast.ai/cli/) for set-up and usage of the CLI. You can search for volume offers using the command:
```text Text theme={null}
vastai search volumes
```
There is a modified list of search params available, for more information, you can add the -- help option to the search.&#x20;
This will bring up a list of available volume offers. You will be able to see the maximum capacity for the volume (in Gigabytes). Just like creating an instance, you can copy the offer ID and create a volume with the command:
```text Text theme={null}
vastai create volume <offer_id> -s <volume_size> -n <name>
```
This will send a command to the host machine to allocate the given space to your volume. You can optionally specify a name with -n, it can be alphanumeric with underscores, with a max length of 64. If all goes well, you should be able to see your volume as created when you run the command&#x20;
```text Text theme={null}
vastai show volumes
```
### How can I create an instance with a volume?
Now that your volume is created, you can use it by creating an instance on the machine with the volume, and passing the volume in the env argument. The format is -v \<volume\_name>:\<mount\_point>, for example:&#x20;
```text Text theme={null}
vastai create instance 874 --image pytorch/pytorch --env '-v V.881:/mnt' --disk 30 --ssh --direct
```
That command mounts your volume at the directory /mnt. The directory does not need to exist in order to be mounted.
### Can I use my volume on a different machine?
You can't directly use the same volume on a different machine, but you can clone the volume to a machine that has an available volume contract.The clone command will create a new volume contract on the new machine, provision the volume, and copy all existing data from the existing volume to the new volume. To clone a volume, you can use the command:
```text Text theme={null}
vastai clone volume <existing_volume_id> <dest_contract_id>
```
where \<dest\_contract\_id> is a volume offer of at least the size of your existing volume.&#x20;
The volumes are independent and do not sync data after the clone is completed. Any changes that occur (on either) volume AFTER the volume is successfully cloned will not be reflected on the other volume.
### How can I delete my volume?
When you're done using it, you can delete your volume using the command&#x20;
```text Text theme={null}
vastai delete volume <volume_id>
```
<Warning>
This will only work if all instances using the volume have been destroyed.&#x20;
</Warning>
### How can I see what instances are using my volume?
The command
```text Text theme={null}
vastai show volumes
```
will display a list of volumes you own, as well as what instances exist that are using that volume.
## A machine with my volume went offline! Am I still being charged?
Just like with normal instances, you are never charged when a machine is offline. This is usually a temporary issue, and when the machine comes back online, volume charges will resume as normal. If you wish to delete the volume in the meantime, you can do so, and you will not be charged when the machine comes back online. If the machine is offline for an extended period of time, please reach out to vast support.&#x20;
## Can I use my volume with a VM instance?
At this time, volumes are only supported for docker instances, and cannot be used with VM instances.

## Common Questions
### Can I delete my account?
You can now delete your Vast.ai account. **Before deleting:**
* Remove all machines, clusters if you are a host.
* `vastai delete machine machine_id`
* `vastai delete cluster cluster_id`
* Destroy / delete all instances and volumes.

### Is there a spend rate limit on my account?
There is a spend rate limit for new users. Make sure you have verified your email; otherwise, your limit is near zero. Once you have verified your email, your spend rate limit increases automatically over time.
If you are an enterprise user, email us at [contact@vast.ai](mailto:contact@vast.ai) to request a larger rate limit increase. Users paying with crypto are also eligible for rate increases.

## Overview
Vast requires pre-payment of credits for GPU rentals. Once credits are purchased, they appear in your account balance.
We accept credit card payments through Stripe and crypto payments through Crypto.com and Coinbase. Use the add credit button to purchase credits one-time. Use the auto-debt feature to have the system automatically top up your account using a saved credit card when it runs low.
### Negative Balances
Vast does **not** immediately delete your instances or data when your account balance reaches zero.
* **When balance reaches zero (or below):**
* Your instances are **stopped automatically** but **not destroyed**.
* This ensures your data remains available so you can copy it off.
* However, since the data is still stored on the machine, you will continue to be billed for **storage on stopped instances** — even if your balance is negative.
* **If you have a payment method saved:**
* Your credit card will be automatically charged periodically to cover any negative balance.
* This allows you to restart and continue using your instances without losing data.
* **If you do not have a payment method saved:**
* The system cannot charge your account.
* Your instances and stored data will be **deleted** to prevent indefinite unpaid usage.
<Tip>
Important: Instances showing in your account are **never free**, even if your balance is negative or zero.
</Tip>
### Auto Debit (credit card only)
You can set a balance threshold to configure auto debits, which will attempt to maintain your balance above the threshold by charging your card periodically.
We recommend setting a threshold around your daily or weekly spend, and then setting an balance email notification threshold around 75% of that value, so that you get notified if the auto billing fails but long before your balance depletes to zero.
There is also an optional debit-mode feature which can be enabled by request for older accounts.
When debit-mode is enabled, your account balance is allowed to go negative (without immediately stopping your instances).
<Warning>
**WARNING**
Your card is charged automatically regardless of whether or not you have
debit-mode enabled. Instances are never free - even stopped instances have
storage charges. Make sure you delete instances when you are done with them -
otherwise, your card will continue to be periodically charged indefinitely.
</Warning>
### Update Frequency
Balances are updated about once every few seconds.
### Credit Card Security
Vast.ai does not see, store or process your credit card numbers, they are passed directly to Stripe (which you can verify in the javascript).
## Refunds
After spending credits, there are absolutely no refunds.
For unspent credits, contact us on the website chat to request a refund. In most cases we can refund unspent credits. Unfortunately Coinbase Commerce does not support refunds, so there are no refunds possible for credits purchased via Coinbase Commerce.
## Pricing
There are separate prices and charges for:
* Active rental (GPU) (in \$/hr)
* Storage costs (in $/GB/month or total $/hr)
* Bandwidth costs (in \$/TB)
You are charged the base active rental cost for every second your instance is in the active/connected state.
You are charged the storage cost (which depends on the size of your storage allocation) for every single second your instance exists and is online (for all states other than offline).
Stopping an instance does not avoid storage costs.
You are charged bandwidth prices for every byte sent or received to or from the instance, regardless of what state it is in.
The prices for base rental, storage, and bandwidth vary considerably from machine to machine, so make sure to check them.
You are not charged active rental or storage costs for instances that are currently offline.
To see a pricing breakdown on your current instances within your Instance page in the console or from offers on the Search page you can hover over the price to see pricing details.

## Common Questions
### If I rent a server and delete if after 10 minutes will I pay for 1 hour of usage or 10 minutes?
You will only be charged for the 10 minutes of usage.
### Can I get a refund?
If you pay with credit card you can get a refund on unspent Vast credits. We do not refund Vast credits bought with crypto.
### Why has the prices changed?
Pricing is fixed by the host, and is specific to each machine and contract. You can refine your search and look for a machine that suits your needs [here](https://cloud.vast.ai/create/).
### Why am I getting the error "No such payment method id None." when I try to add credit?
Before buying credit with Stripe you must add a card!
### Am I charged for "Loading" instances?
No, you are not charged when it says "Loading".
### If my account is negative a few \$, what will happen? What happens if my Vast balance is negative?
It says in the Billing page: "You have a negative credit balance. Your instances are stopped and can resume once you pay the balance owed".
### Why am I getting charge more per hour than expected?
You may be see your Vast credit decline at a greater rate than expected due to upload and downloads costs, which is not shown in your $cost/hr or$cost/day pricing breakdowns as it is charged on a usage basis and not a constant rate. You can find these rates for bandwidth usage in the Internet: section of the pricing details, which you can see when you hover over the price in the bottom right-hand corner of instance cards within the Instance console page. You can also see pricing detail before instance creation from hovering over the prices on the Search page. You can also get a detailed document of your billing history by "Generate Billing History" within the Billing page of the console.
### Why are my GPUs not showing up in the list?
There are over 10,000+ listings on vast, and search only displays a small subset. You will usually not be able to find any one specific machine through most normal searches. To test that your machine is listed correctly, you can use the CLI:
vastai search offers 'machine\_id=12345 verified=any'
Replace 12345 with your actual machine ID
If your machine is verified, you should still be able to find it without the verified=any.
[Use the CLI (preferred)](/cli/get-started)

### How does billing work?
Once you enter a credit card and an email address and both are verified you can then increase your credit balance using one-time payments with the add credit button.
Whenever your credit balance hits zero or below, your instances will be stopped automatically, but not destroyed.
You are still charged storage costs for stopped instances, so it is important to destroy instances when you are done using them.
Your credit card will be automatically charged periodically to pay off any outstanding negative balance.
### Can you bill my card automatically so I don't have to add credit in advance?
You can set a balance threshold to configure auto billing, which will attempt to maintain your balance above the threshold.
We recommend setting a threshold around your daily or weekly spend, and then setting an balance email notification threshold around 75% of that value, so that you get notified if the auto billing fails but long before your balance depletes to zero.
There is also an optional debit-mode feature which can be enabled by request for older accounts.
When debit-mode is enabled, your account balance is allowed to go negative (without immediately stopping your instances).
### I didn't enable debit-mode - what are these automatic charges to my card?
Your card is charged automatically regardless of whether or not you have debit-mode enabled.
Instances are never free - even stopped instances have storage charges.
Make sure you delete instances when you are done with them - otherwise, your card will continue to be periodically charged indefinitely.
### How does pricing work?
There are separate prices and charges for:
* Active rental (GPU) costs
* Storage costs
* Bandwidth costs
You are charged the base active rental cost for every second your instance is in the active/connected state.
You are charged the storage cost (which depends on the size of your storage allocation) for every second your instance exists and is online, regardless of what state it is in: active, inactive, loading, etc.
Stopping an instance does not avoid storage costs.
You are charged bandwidth prices for every byte sent or received to or from the instance, regardless of what state it is in.
The prices for base rental, storage, and bandwidth vary considerably from machine to machine, so make sure to check them.
You are not charged active rental or storage costs for instances that are currently offline.
### What is the billing frequency?
Balances are updated about once every few seconds.
### Why should I trust vast.ai with my credit card info?
You don't need to: Vast.ai does not see, store or process your credit card numbers, they are passed directly to Stripe (which you can verify in the javascript).
### Do you support PayPal? What about cryptocurrency?
We currently support major credit cards through stripe and crypto payments through Coinbase and crypto.com.

## Instance Lifecycle
### What does "Lifetime" mean on my instance?
Every instance offer has a **Max Duration**. When you accept an offer and create an instance, this becomes the instance lifetime and begins counting down. When the lifetime expires, the instance is automatically stopped.
The host can extend the contract (adding more lifetime), but this is at their discretion. **Important:** Always assume your instance will be lost once the lifetime expires and copy out any important data before then.
### How can I restart programs when my instance restarts?
**For custom command instances:** Your command runs automatically on startup.
**For SSH instances:** Place startup commands in `/root/onstart.sh`. This script runs automatically on container startup.
```bash theme={null}
# Example /root/onstart.sh
#!/bin/bash
cd /workspace
python train.py --resume
```
## Environment Configuration
### How do I set environment variables?
Use the `-e` Docker syntax in the docker create/run options:
```bash theme={null}
-e TZ=UTC -e TASKID="TEST"
```
To make variables visible in SSH/Jupyter sessions, export them to `/etc/environment`:
```bash theme={null}
# Export variables with underscores
env | grep _ >> /etc/environment
# Or export all variables
env >> /etc/environment
```
You can also set global environment variables in your account Settings page.
### How do I get the instance ID from within the container?
Use the `VAST_CONTAINERLABEL` environment variable:
```bash theme={null}
echo $VAST_CONTAINERLABEL
# Output: C.38250
```
### How can I find OPEN\_BUTTON\_TOKEN?
SSH into your instance or open Jupyter terminal and run:
```bash theme={null}
echo $OPEN_BUTTON_TOKEN
```
Alternatively, check the instance logs.
## Controlling Instances
### How do I stop an instance from within itself?
A special instance API key is pre-installed. Install the CLI and use it:
```bash theme={null}
# Install CLI
pip install vastai
# Test with start (no-op if already running)
vastai start instance $CONTAINER_ID
# Stop the instance
vastai stop instance $CONTAINER_ID
```
If `$CONTAINER_ID` is not defined, check your environment variables with `env`.
### Can I run Docker within my instance?
No, Vast.ai does not support Docker-in-Docker due to security constraints. Each Docker container must run on a separate instance.
## Data and Storage
### Can I change disk size after creating an instance?
**No.** Disk size is permanent and cannot be changed after instance creation. If you run out of space, you'll need to create a new instance with a larger disk.
**Tip:** Always allocate more space than you think you need to avoid interruptions.
### What happens to my data when an instance stops?
* **Stopped instances:** Data persists, storage charges continue
* **Destroyed instances:** All data is permanently deleted
* **Lifetime expired:** Instance stops, data remains until destroyed
Always backup important data to external storage.

}
}
]
})
}}
/>
## Jupyter
### What is the HTTPS security warning?
When accessing Jupyter, browsers show a security warning because we use self-signed certificates. To fix:
1. Download and install our [TLS certificate](/documentation/instances/jupyter)
2. **Windows/Linux:** Can bypass by clicking Advanced → Proceed
3. **macOS:** Must install certificate in Keychain Access
Installing the certificate removes the warning permanently.
### Why are Jupyter transfers slow?
Jupyter's upload/download is not optimized for large files. Alternatives:
* Use SCP/SFTP for large transfers
* Use cloud storage (S3, GCS)
* Use the Vast CLI copy commands
* Zip multiple files before downloading
### How do I delete files in Jupyter to free space?
Jupyter moves deleted files to trash. To permanently delete:
```bash theme={null}
# In Jupyter terminal
rm -r ~/.local/share/Trash
```
### How do I run Colab notebooks?
1. Select the [PyTorch template](https://cloud.vast.ai/?ref_id=43484\&template_id=e4c5e88bc289f4eecb0c955c4fe7430d) with Jupyter enabled
2. Start your instance
3. Download the Colab notebook as `.ipynb`
4. Upload to Jupyter
5. Install any missing dependencies with `pip install`
For direct Colab connection, see our [Colab guide](/google-colab).
### How do I download multiple files from Jupyter?
**Jupyter Lab:** Shift-click to select multiple files, right-click to download
**Jupyter Notebook:** Must download individually or zip first:
```bash theme={null}
# Install zip
apt-get install -y zip
# Zip a directory
zip -r all_files.zip /path/to/files/
```
### Missing library or package errors?
Install dependencies in Jupyter terminal:
```bash theme={null}
# System packages
apt-get install -y PACKAGE_NAME
# Python packages
pip install PACKAGE_NAME
```
## SSH Access
### How do I connect via SSH on Linux/Mac?
1. Generate an SSH keypair:
```bash theme={null}
ssh-keygen -t rsa
```
2. Load the key and verify:
```bash theme={null}
ssh-add
ssh-add -l
```
3. Get your public key:
```bash theme={null}
cat ~/.ssh/id_rsa.pub
```
4. Copy the **entire output** (including `ssh-rsa` prefix and `user@host` suffix) to your [Keys section](https://cloud.vast.ai/manage-keys/)
Example of complete SSH key:
```
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAZBAQDdxWwxwN5Lz7ubkMrxM5FCHhVz... bob@velocity
```
### How do I connect via SSH from Windows?
Two options:
1. **Windows Subsystem for Linux (WSL)** - Follow Linux/Mac instructions above
2. **PuTTY** - See our [Windows SSH Guide](/documentation/instances/windows-ssh-guide)
Make sure to save the key in SSH RSA-2 format when using PuTTY.
### What is tmux and how do I use it?
We connect you to a tmux session by default for reliability. Common commands:
* **Create new terminal:** `Ctrl+b, c`
* **Switch terminals:** `Ctrl+b, n`
* **Split screen:** `Ctrl+b, %` (vertical) or `Ctrl+b, "` (horizontal)
Search "tmux cheat sheet" for more commands.
### Can I disable tmux?
Not recommended (SSH can be unstable), but if needed, add to your onstart:
```bash theme={null}
touch ~/.no_auto_tmux
```
### SSH asks for a password - what's wrong?
There is no SSH password - Vast.ai uses SSH key authentication only. If SSH asks for a password:
* Your SSH key wasn't added correctly to your account
* You didn't copy the entire public key (must include `ssh-rsa` prefix and `user@host` suffix)
* Your SSH client is misconfigured
* The private key isn't loaded in your SSH agent
Double-check that you copied the complete public key to your Keys section.

"text": "Just use an out-of-range port above 70000. For example: -p 70000:70000 -p 70001:70001. This allows you to have matching internal and external port numbers."
}
}
]
})
}}
/>
## Port Configuration
### How can I open custom ports?
Add -p arguments in the docker create/run options box in the template configuration or image config editor pop-up menu. To open ports 8081 and 8082, use something like this:
```text theme={null}
-p 8081:8081 -p 8082:8082
```
This will result in additional arguments to docker create/run to expose those internal ports, which will be mapped to random external ports. Any ports exposed in these docker options are in addition to ports exposed through EXPOSE commands in the docker image, and the ports 22 or 8080 which may be opened automatically for SSH or Jupyter.
After the instance has loaded, you can find the corresponding external public IP by opening the IP Port Info pop-up (button on top of the instance) and then looking for something like:
```text theme={null}
65.130.162.74:33526 -> 8081/tcp
```
In this case, the public IP 65.130.162.74:33526 can be used to access anything you run on port 8081 inside the instance. As a simple test case, you can run a simple minimal web browser inside the instance with the following command:
```text theme={null}
python -m http.server 8081
```
Which you would then access in this example by loading 65.130.162.74:33526 in your web browser.
### How can I open an identity port map like 32001:32001 where external are the same?
Just use an out-of-range port above 70000:
```text theme={null}
-p 70000:70000 -p 70001:70001
```

### On-Demand (High Priority)
* Fixed price set by the host
* Runs as long as you want
* Cannot be interrupted
* More expensive but reliable
### Interruptible (Low Priority)
* You set a bid price
* Can be stopped by higher bids
* Saves 50-80% on costs
* Good for fault-tolerant workloads
## How do interruptible instances compare to AWS Spot?
**Similarities:**
* Both can be interrupted
* Both offer significant savings
**Differences:**
* Vast.ai uses direct bidding (you control your bid price)
* AWS uses market pricing
* No 24-hour limit like GCE preemptible instances
* Vast.ai instances can run indefinitely if not outbid
## What happens when my interruptible instance loses the bid?
Your instance is stopped (killing running processes). Important considerations:
* **Save work frequently** to disk
* **Use cloud storage** for backups
* **Instance may wait long** to resume
* **Implement checkpointing** for long jobs
When using interruptible instances, always design your workload to handle interruptions gracefully.
## DLPerf Scoring
### What is DLPerf?
DLPerf (Deep Learning Performance) is our scoring function that estimates performance for typical deep learning tasks. It predicts iterations/second for common tasks like training ResNet50 CNNs.
**Example scores:**
* V100: \~21 DLPerf
* 2080 Ti: \~14 DLPerf
* 1080 Ti: \~10 DLPerf
A V100 (21) is roughly 2x faster than a 1080 Ti (10) for typical deep learning.
### Is DLPerf accurate for my workload?
DLPerf is optimized for common deep learning tasks:
* ✅ CNN training (ResNet, VGG, etc.)
* ✅ Transformer models
* ✅ Standard computer vision
* ⚠️ Less accurate for unusual compute patterns
* ⚠️ Not optimized for non-ML workloads
For specialized workloads, benchmark on different GPUs yourself. While not perfect, DLPerf is more useful than raw TFLOPS for most ML tasks.

## Docker Configuration
### What Docker options can I use?
Add Docker run arguments in the template configuration:
```bash theme={null}
# Port mapping
-p 8080:8080 -p 8081:8081
# Environment variables
-e TZ=UTC -e CUDA_VISIBLE_DEVICES=0
# Shared memory (for PyTorch)
--shm-size=32gb
```
### Can I use my own Docker images?
Yes! When creating a template:
1. Specify your Docker image URL
2. Ensure it's publicly accessible or provide auth
3. Use standard Docker Hub, GHCR, or other registries
4. Include all dependencies in the image
### Why can't I run Docker inside my instance?
Docker-in-Docker is disabled for security. Alternatives:
* Use separate instances for different containers
* Build multi-service images
* Use process managers like supervisord
## Performance Optimization
### How can I maximize GPU utilization?
1. **Batch size optimization:**
* Increase until GPU memory is nearly full
* Monitor with `nvidia-smi`
2. **Data pipeline:**
* Pre-process data
* Use multiple data loader workers
* Cache datasets locally
3. **Mixed precision training:**
```python theme={null}
# PyTorch example
from torch.cuda.amp import autocast
with autocast():
output = model(input)
```
### Why is my training slower than expected?
Common issues:
* **CPU bottleneck** - Check data loading
* **Network I/O** - Download data to local storage first
* **Wrong GPU mode** - Ensure CUDA is enabled
* **Thermal throttling** - Some consumer GPUs throttle
* **PCIe bandwidth** - Multi-GPU setups may be limited
## Storage and Volumes
### What's the difference between instance storage and volumes?
**Instance Storage:**
* Included with every instance
* Deleted when instance is destroyed
* Size set at creation (cannot change)
* Faster performance
**Volumes:**
* Persistent across instances
* Can be attached/detached
* Additional cost
* Good for datasets and checkpoints
### How do I use volumes?
1. Create a volume in the Volumes section
2. Attach when creating an instance
3. Mount point specified in template
4. Data persists after instance destruction
See [Volumes Guide](/documentation/instances/volumes) for details.
## Environment Setup
### How do I install additional packages?
In Jupyter terminal or SSH:
```bash theme={null}
# System packages
apt-get update && apt-get install -y package-name
# Python packages
pip install package-name

You can reset an API key by clicking the **Reset** button. A new key will be automatically generated. To remove a key, simply click the **Delete** button.
## Session Keys
A **session key** is a temporary key that allows access to your Vast.ai account. These keys are automatically created when you log in and will expire in one week.
However, for security reasons, it's important to review your session keys regularly. You can view a list of all active session keys and see which devices are currently logged into your account. If you notice any session keys that you don't recognize, or if a device is no longer in use, you can delete those keys to immediately remove access. This helps keep your account secure and ensures only your devices remain connected.

Turn your audience into earnings! Share your unique Vast.ai referral link (or a public template link), and when someone creates a **new client account** and buys credits, you get **3%** of everything they spend — for the **lifetime** of their account.
Better yet, you can cash out **75% of those referral credits** via **Stripe Connect, PayPal, or Wise**.
<Warning>
In order to receive payouts for referrals you MUST create a new account. You are unlikely to be able to receive payouts to any bank account outside Vast if the account you are using for referrals has ever rented instances or hosted machines
</Warning>
## How It Works
1. **Share Your Link** – Post it on your site, in videos, blogs, or wherever your audience is.
2. **They Join & Buy Credits** – New users sign up through your link and purchase credits.
3. **You Earn** – Get 3% of their lifetime spend as referral credits.
4. **Cash Out or Spend** – Use credits on Vast, or withdraw up to 75% as cash.
<Note>
If someone spends $1,000 over time, you get $30 in referral credits — forever.
</Note>
## Payout Rules — Important!
To **receive cash payouts** (outside of Vast), you **must** use a **dedicated referral account**:
* If you’ve **ever rented instances or hosted machines** on an account, you **cannot** cash out until your referral earnings exceed your lifetime instance spend.
* If you just want credits to rent Vast instances, you can use your main account.
**Why a separate account?**<br />
It keeps your referral earnings clear and makes sure you’re payout-eligible.
<Warning>
**Example:**
* You’ve earned \$300 in referral credits.
* Lifetime charges on your account: \$855.
* Since $300 < $855, you can't cash out until referral earnings exceed \$855.
</Warning>
## Getting Your Referral Link
1. Create a new account for referrals.
2. Go to [**Settings**](https://cloud.vast.ai/account/) → **Referral Link**.

3. Copy the link.
4. Share it!
<Note>
**Note:** You can’t refer yourself or any account connected to you — those won’t earn rewards.
</Note>
## Using Templates for Referrals
Want to make referrals even easier? Use [**Templates page**](https://cloud.vast.ai/templates/) to create your template.
&#x20;A template can pre-load:
* A Docker image
* Launch mode(s)
* Onstart script
* Environment variables
**Example:** The Stable Diffusion template loads the image, sets up Automatic1111 WebUI, starts Jupyter, and preps the environment — ready to go.
Create [your own template](/documentation/templates/creating-templates) for a use case, set it to **public**, then share its **template referral link.** The link will have this format:
<Note>
**Note:** You can’t refer yourself or any account connected to you — those won’t earn rewards.
</Note>
Your audience clicks → Vast loads with your settings → they sign up → you earn.
**Where to use it:** GitHub repos, videos, blog posts — anywhere your audience needs a “click and run” setup.

### I stopped my instance, and now when I try to restart it the status is stuck on "scheduling". What is wrong?
When you stop an instance, the gpu(s) it was using may get reassigned. When you later then try to restart the instance, it tries to get those gpu(s) back - that is the "scheduling" phase. If another high priority job is currently using any of the same gpu(s), your instance will be stuck in "scheduling" phase until the conflicting jobs are done. We know this is not ideal, and we are working on ways to migrate containers across gpus and machines, but until then we recommend not stopping an instance unless you are ok with the risk of waiting a while to restart it."
### All my instances keep stopping, switching to inactive status, even though I didn't press the stop button. What's going on?
Check your credit balance. If it hits zero or below, your instances will be stopped automatically.
### I keep getting this error: spend\_rate\_limit. What's going on?
There is a spend rate limit for new accounts. The limit is extremely small for unverified accounts, so make sure to verify your email. The limit increases over time, so try a cheaper instance type or wait a few hours. If you are still having trouble, use the online support chat in the lower right.
### I tried to connect with ssh and it asked for a password. What is the password?
There is no ssh password, we use ssh key authentication. If ssh asks for a password, typically this means there is something wrong with the ssh key that you entered or your ssh client is misconfigured.
On Ubuntu or Mac, first you need to generate an rsa ssh public/private keypair using the command:
```text theme={null}
ssh-keygen -t rsa
```
Next you may need to force the daemon to load the new private key, and confirm it's loaded:
```text theme={null}
ssh-add; ssh-add -l
```
Then get the contents of the public key with:
```text theme={null}
cat ~/.ssh/id_rsa.pub
```
Copy the entire output to your clipboard, then paste that into a new SSH Key in your [Keys section](https://cloud.vast.ai/manage-keys/). The key text *includes* the opening "ssh-rsa" part and the ending "user\@something" part. If you don't copy the entire thing, it won't work.
Example SSH key text:
```text theme={null}
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDdxWwxwN5Lz7ubkMrxM5FCHhVzOnZuLt5FHi7J8zFXCJHfr96w+ccBOBo2rtBBTTRDLnJjIsKLgBcC3+jGyZhpUNMFRVIJ7MeqdEHgHFvUUV/uBkb7RjbyyFcb4BCSYNggUZkMNNoNgEa3aqtBSzt47bnuGqqszs9bfDCaPFtr9Wo0b8p4IYil/gfOYBkuSVwkqrBCWrg53/+T2rAk/02mWNHXyBktJAu1q7qTWcyO68JTDd0sa+4apSu+CsJMBJs3FcDDRAl3bcpiKwRbCkQ+N6sol4xDV3zQRebUc98CJPh04Gnc41W02lmdqGL2XG5U/rV8/JM7CawKiIz3dbkv bob@velocity

# Architecture
Source: https://docs.vast.ai/documentation/serverless/architecture
Understand the architecture of Vast.ai Serverless, including the Serverless System, GPU Instances, and User (Client Application). Learn how the system works, how to use the routing process, and how to create Worker Groups.
The Vast.ai Serverless solution manages groups of GPU instances to efficiently serve applications, automatically scaling up or down based on load metrics defined by the Vast PyWorker. It streamlines instance management, performance measurement, and error handling.
## Endpoints and Worker Groups
The Serverless system needs to be configured at two levels:
* **Endpoints:** The highest level clustering of instances for the Serverless system, consisting of a named endpoint string, a collection of Worker groups, and hyperparameters.
* **Worker Groups**: A lower level organization that lives within an Endpoint. It consists of a [template](/documentation/instances/templates) (with extra filters for search), a set of GPU instances (workers) created from that template, and hyperparameters. Multiple Worker Groups can exist within an Endpoint.
Having two-level scaling provides several benefits:
1. **Comparing Performance Metrics Across Hardware**: Suppose you want to run the same templates on different hardware to compare performance metrics. You can create several groups, each configured to run on specific hardware. By leaving this setup running for a period of time, you can review the metrics and select
the most suitable hardware for your users' needs.
2. **Smooth Rollout of a New Model**: If you're using TGI to handle LLM inference with LLama3 and want to transition to LLama4, you can do so gradually. For a smooth rollout where only 10% of user requests are handled by LLama4, you can create a new Worker Group under the existing Endpoint. Let it run for a while,
review the metrics, and then fully switch to LLama4 when ready.
3. **Handling Diverse Workloads with Multiple Models**: You can create an Endpoint to manage LLM inference using TGI. Within this group, you can set up multiple
Worker Groups, each using a different LLM to serve requests. This approach is beneficial when you need a few resource-intensive models to handle most requests, while smaller, more cost-effective models manage overflow during workload spikes.
It's important to note that having multiple Worker Groups within a single Endpoint is not always necessary. For most users, a single Worker Group within an Endpoint provides an optimal setup.
You can create Worker Groups using our [Serverless-Compatible Templates](/documentation/serverless/text-generation-inference-tgi), which are customized versions of popular templates on Vast, designed to be used on the serverless system.
## System Architecture
The system architecture for an application using Vast.ai Serverless includes the following components:
* **Serverless System**&#x20;
* **GPU Instances**&#x20;

### Example Workflow&#x20;
1. A client initiates a request to the Serverless system by invoking the `https://run.vast.ai/route/` endpoint.
2. The Serverless system returns a suitable worker address. In the example above, this would be `ip_address_2` since that GPU instance is 'Ready'.
3. The client calls the GPU instance's specific API endpoint, passing the authentication info returned by `/route/` along with payload parameters.
4. The PyWorker on the GPU instance receives the payload and forwards it to the ML model. After model inference, the PyWorker receives the results.
5. The PyWorker sends the model results back to the client.
6. Independently and concurrently, each PyWorker in the Endpoint sends its operational metrics to the Serverless system, which it uses to make scaling decisions.
### Two-Step Routing Process
This 2-step routing process is used for security and flexibility. By having the client send payloads directly to the GPU instances, your payload information is never stored on Vast servers.
The `/route/` endpoint signs its messages with a public key available at `https://run.vast.ai/pubkey/`, allowing the GPU worker to validate requests and prevent unauthorized usage.
# Comfy UI
Source: https://docs.vast.ai/documentation/serverless/comfy-ui
Learn how to use Comfy UI with Vast.ai Serverless for image generation workflows.
The [Comfy UI serverless template](https://cloud.vast.ai/?template_id=f8aac491656a1d1040e7dfc5f8fcf059) can be used to run Comfy stable diffusion models on Vast GPU instances. This page documents required environment variables and endpoints to get started.
A full PyWorker and Client implementation can be found [here](https://github.com/vast-ai/pyworker/tree/main).
# Environment Variables
* `HF_TOKEN`(string): HuggingFace API token with read permissions, used to download gated models. Read more about HuggingFace tokens [here](https://huggingface.co/docs/hub/en/security-tokens).
* `COMFY_MODEL`(string): Text2Image model being used.&#x20;
* options: `"sd3"`, `"flux"`
# Endpoints
## **/**&#x70;rompt/
The ComfyUI defined endpoint to generate an image. After receving a GPU worker address from the `/route/` endpoint, a `/prompt/` endpoint would have the following structure.
### Inputs
For both "sd3" and "flux":&#x20;
Payload:
* `prompt`(string): The model prompt used to generate the image.
* `width`(int): Width in pixels of the resulting generated image.
* `height`(int): Height in pixels of the resulting generated image.
* `steps`(int): Number of diffusion steps taken during image generation. The assumed default is 28.
* `seed`(int): The value used to initialize the random noise pattern in the diffusion model. Used for reproducability.&#x20;
Auth\_data:
* `signature`(string): A cryptographic string that authenticates the url, cost, and reqnum fields in the response, proving they originated from the server. Clients can use this signature, along with the server's public key, to verify that these specific details have not been tampered with.
* `cost`(float): The estimated compute resources for the request. The units of this cost are defined by the PyWorker.&#x20;
* `endpoint`(string): Name of the Endpoint.
* `reqnum`(int): The request number corresponding to this worker instance. Note that workers expect to receive requests in approximately the same order as these reqnums, but some flexibility is allowed due to potential out-of-order requests caused by concurrency or small delays on the proxy server.
* `url`(string): The address of the worker instance to send the request to.
```json JSON icon="js" theme={null}
{
"payload": {
"prompt": "a majestic lion with a flowing mane, fantasy art style",
"width": 1024,
"height": 1024,
"steps": 28,
"seed": 55512345
},
"auth_data": {
"signature": "mock_signature_from_routing_service_abc123",
"cost": 100,
"endpoint": "comfyui-flux-default",
"reqnum": "req_789xyz",
"url": "http://127.0.0.1:8188/" //this is the base URL of the worker, 'prompt/' is appended to the end
}
}
```
### Outputs
* `prompt_id`(string): A unique identifier assigned by the ComfyUI instance for this specific workflow execution or prompt.
* `number`(int): A sequential number assigned by the ComfyUI instance to this prompt. This number reflects the order in which prompts are received or processed by the worker.
* `node_errors`(object): An object that contains details about any errors that occurred within specific nodes during the workflow execution.
* `outputs`(object): An object containing the outputs generated by specific nodes in the ComfyUI workflow. The keys of this object are the string identifiers of the nodes that produced output
```json JSON icon="js" theme={null}

}
}
```
## /custom\_workflow/
Allows a client to send a complete, user-defined ComfyUI workflow (in JSON format) to the server for execution. It includes the `payload` and `auth_data` objects, but modified according to the user's design.
The workflow is a direct ComfyUI graph. Here is an example, similar to the SD3 workflow.

# Creating New PyWorkers
Source: https://docs.vast.ai/documentation/serverless/creating-new-pyworkers
Learn how to create a new PyWorker for Vast.ai Serverless. Understand the structure of a PyWorker, the required files, and how to implement the server.py module.
This guide walks you through the structure of a PyWorker. By the end, you will know all of the pieces of a PyWorker and be able to create your own. &#x20;
<Note>
Vast has pre-made templates with PyWorkers already built-in. Search the [templates section](/documentation/templates/quickstart) first to see if a supported template works for your use case.&#x20;
</Note>
[This repo](https://github.com/vast-ai/pyworker/tree/main) contains all the components of a PyWorker. Simply for pedagogical purposes, the `workers/hello_world/` PyWorker is created for an LLM server with two API endpoints:
1. `/generate`: generates a LLM response and sends a JSON response
2. `/generate_stream`: streams a response one token at a time
Both of these endpoints take the same API JSON payload:
```json JSON icon="js" theme={null}
{
"prompt": String,
"max_response_tokens": Number | null
}
```
***
## Structure
All PyWorkers have four files:
```text Text theme={null}
.
└── workers
└── hello_world
├── __init__.py # blank file
├── data_types.py # contains data types representing model API endpoints
├── server.py # contains endpoint handlers
└── test_load.py # script for load testing
```
All of the classes follow strict type hinting. It is recommended that you type hint all of your functions. This will allow your IDE or VSCode with `pyright` plugin to find any type errors in your implementation. You can also install `pyright` with `npm install pyright` and run `pyright` in the root of the project to find any type errors.
### \_\_init\_\_.py
The `__init__.py`file is left blank. This tells the Python interpreter to treat the hello\_world directory as a package. This allows us to import modules from within the directory. &#x20;
### data\_types.py
This file defines how the PyWorker interacts with the ML model, and must adhere to the common framework laid out in `lib/data_types.py`. The file implements the specific request structure and payload handling that will be used in `server.py`.&#x20;
Data handling classes must inherit from `lib.data_types.ApiPayload`. `ApiPayload` is an abstract class that needs several functions defined for it. Below is an example implementation from the hello\_world PyWorker that shows how to use the `ApiPayload` class.&#x20;
```python icon="python" Python theme={null}
import dataclasses
import random
from typing import Dict, Any
from transformers import AutoTokenizer # used to count tokens in a prompt
import nltk # used to download a list of all words to generate a random prompt and benchmark the LLM model
from lib.data_types import ApiPayload
nltk.download("words")
WORD_LIST = nltk.corpus.words.words()
#### you can use any tokenizer that fits your LLM. `openai-gpt` is free to use and is a good fit for most LLMs
tokenizer = AutoTokenizer.from_pretrained("openai-community/openai-gpt")
@dataclasses.dataclass
class InputData(ApiPayload):
prompt: str
max_response_tokens: int
@classmethod
def for_test(cls) -> "ApiPayload":
"""defines how create a payload for load testing"""
prompt = " ".join(random.choices(WORD_LIST, k=int(250)))
return cls(prompt=prompt, max_response_tokens=300)
def generate_payload_json(self) -> Dict[str, Any]:
"""defines how to convert an ApiPayload to JSON that will be sent to model API"""
return dataclasses.asdict(self)
def count_workload(self) -> float:

return len(tokenizer.tokenize(self.prompt))
@classmethod
def from_json_msg(cls, json_msg: Dict[str, Any]) -> "InputData":
"""

in this case `InputData` defined above represents the data sent to the model API.
AuthData is data generated by the serverless system in order to authenticate payloads.
In this case, the transformation is simple and 1:1. That is not always the case. See comfyui's PyWorker
for more complicated examples
"""
errors = {}
for param in inspect.signature(cls).parameters:
if param not in json_msg:
errors[param] = "missing parameter"
if errors:
raise JsonDataException(errors)
return cls(
**{
k: v
for k, v in json_msg.items()
if k in inspect.signature(cls).parameters
}
)
```
Your specific use case could require additional classes or methods. Reference the TGI worker as another example.
### server.py
For every ML model API endpoint you want to use, you must implement an `EndpointHandler`. This class handles incoming requests, processes them, sends them to the model API server, and finally returns an HTTP response with the model's results. `EndpointHandler` has several abstract functions that must be implemented. Here, we implement the `/generate` endpoint functionality for the PyWorker by creating the `GenerateHandler` class that inherits from `EndpointHandler`.
![EndpointHandler class allows the PyWorker and Model Server to communicate.](https://archbee-image-uploads.s3.amazonaws.com/pNFur-Vy38DOi0g2bo5iM-Xkpobv-ceFYbciTKsmDIK-20250529-195514.png)
```python icon="python" Python theme={null}
"""
AuthData is a dataclass that represents Authentication data sent from the serverless system to the client requesting a route.
When a user requests a route, see Vast's Serverless documentation for how routing and AuthData
work.
When a user receives a route for this PyWorker, they'll call PyWorkers API with the following JSON:
{
auth_data: AuthData,
payload : InputData # defined above
}

return web.json_response(data=data)
case code:

```
We also handle `GenerateStreamHandler` for streaming responses. It is identical to `GenerateHandler`, except that this implementation creates a web response:
```python icon="python" Python theme={null}
class GenerateStreamHandler(EndpointHandler[InputData]):
@property
def endpoint(self) -> str:
return "/generate_stream"
@classmethod

await res.write_eof()
log.debug("Done streaming response")
return res
case code:
log.debug("SENDING RESPONSE: ERROR: unknown code")
return web.Response(status=code)
```
You can now instantiate a Backend and use it to handle requests.

PyWorker works as a man-in-the-middle between the client and model API. It's function is:
1. receive request from client, update metrics such as workload of a request, number of pending requests, etc.
2a. transform the data and forward the transformed data to model API
2b. send updated metrics to autoscaler
3. transform response from model API(if needed) and forward the response to client
PyWorker forward requests to many model API endpoint. each endpoint must have an EndpointHandler. You can also
write function to just forward requests that don't generate anything with the model to model API without an
EndpointHandler. This is useful for endpoints such as healthchecks. See below for example

### test\_load.py
Once a Serverless Endpoint is setup with a \{\{Worker\_Group}}, the `test_load` module lets us test the running instances:
```python icon="python" Python theme={null}
from lib.test_harness import run
from .data_types import InputData
WORKER_ENDPOINT = "/generate"
if __name__ == "__main__":
run(InputData.for_test(), WORKER_ENDPOINT)
```
To run the script, provide the following parameters:
* -n is the total number of requests to be send to the Endpoint
* -rps is the rate (rate per second) at which the requests will be sent
* -k is your Vast API key. You can define it in your environment or paste it into the command
* -e is the name of the Serverless Endpoint
You can run the following command from the root of the PyWorker repo:
```sh Text theme={null}
python3 workers.hello_world.test_load -n 1000 -rps 0.5 -k "$API_KEY" -e "$ENDPOINT_NAME"
```
<Warning>
Be sure to define "API\_KEY" and "ENDPOINT\_NAME" in your environment before running, or replace these names with their actual values.
</Warning>
A successful test with n = 10 requests would look like the following. This test used 4 different GPU workers in the Worker Group for the 10 requests it was sent.

***
These are all the parts of a PyWorker! You will also find a client.py module in the worker folders of the repo. While it is *not* part of the PyWorker, Vast provides it as an example of how a user could interact with their model on the serverless system. The client.py file is not needed for the PyWorker to run on a GPU instance, and is intended to run on your local machine. The PyWorker [Overview](/documentation/serverless/overview) page shows more details.
# Debugging
Source: https://docs.vast.ai/documentation/serverless/debugging
Learn how to debug issues with Vast.ai Serverless. Understand the worker errors, increasing and decreasing load, and how to check the instance logs.
## Worker Errors
The [Vast PyWorker](https://github.com/vast-ai/pyworker/tree/main) framework automatically detects some errors, while others may cause the instance to timeout. When an error is detected, the Serverless system will destroy or
reboot the instance. To manually debug an issue, check the instance logs available via the logs button on the instance page in the GUI. All PyWorker issues will be logged here.
If further investigation is needed, ssh into the instance and find the model backend logs location by running:
```sh Text theme={null}
echo "$MODEL_LOG"
```
And PyWorker logs:
```sh Text theme={null}
echo "${WORKSPACE_DIR:-/workspace}/pyworker.log"
```
### Increasing Load
To handle high load on instances:
* **Set&#x20;**`test_workers`**&#x20;high**: Create more instances initially for Worker Groups with anticipated high load.
* **Adjust&#x20;**`cold_workers`: Keep enough workers around to prevent them from being destroyed during low initial load.
* **Increase&#x20;**`cold_mult`: Quickly create instances by predicting higher future load based on current high load. Adjust back down once enough instances are created.
* **Check&#x20;**`max_workers`: Ensure this parameter is set high enough to create the necessary number of workers.
### Decreasing Load
To manage decreasing load:
* **Reduce&#x20;**`cold_workers`: Stop instances quickly when the load decreases to avoid unnecessary costs. The serverless system will handle this automatically, but manual adjustment can help if needed.
# Getting Started With Serverless
Source: https://docs.vast.ai/documentation/serverless/getting-started-with-serverless
Learn how to get started with Vast.ai Serverless. Understand the prerequisites, setup process, and how to use the serverless engine.
<Warning>
For users not familiar with Vast.ai's Serverless engine, we recommend starting with the [Serverless Architecture documentation](/documentation/serverless/architecture). It will be helpful in understanding how the system operates, processes requests, and manages resources.
</Warning>
# Overview & Prerequisites
Vast.ai provides pre-made serverless templates ([vLLM](/documentation/serverless/vllm), [ComfyUI](/documentation/serverless/comfy-ui)) for popular use cases, and can be used with minimal setup effort. In this guide, we will setup a serverless engine to handle inference requests to a model using vLLM, namely Qwen3-8B , using the pre-made Vast.ai vLLM serverless template. This prebuilt template bundles vLLM with scaling logic so you don’t have to write custom orchestration code. By the end of this guide, you will be able to host the Qwen3-8B model with dynamic scaling to meet your demand.
<Note>
This guide assumes knowledge of the Vast CLI. An introduction for it can be found [here](/cli/get-started).
</Note>
Before we start, there are a few things you will need:
1. A Vast.ai account with credits
2. A Vast.ai [API Key](/documentation/reference/keys)
3. A HuggingFace account with a [read-access API token](https://huggingface.co/docs/hub/en/security-tokens)
# Setting Up a vLLM + **Qwen3-8B** Serverless Engine
<Steps>
<Step title="Configure User Environment Variables">
Navigate to the user account settings page [here](https://cloud.vast.ai/account/) and drop down the "Environment Variables" tab. In the Key field, add "HF\_TOKEN", and in the Value field add the HuggingFace read-access token. Click the "+" button to the right of the fields, then click "Save Edits".

</Step>
<Step title="Prepare a Template for our Workers">
Templates encapsulate all the information required to run an application on a GPU worker, including machine parameters, docker image, and environment variables.
Navigate to the [Templates Page](https://cloud.vast.ai/templates/), select the Serverless filter, and click the Edit button on the 'vLLM + Qwen/Qwen3-8B (Serverless)' template.&#x20;
In the Environment Variables section, "Qwen/Qwen3-8B" is the default value for `MODEL_NAME`, but can be changed to any compatible vLLM model on HuggingFace. Set this template to Private and click Save & Use.&#x20;

<Check>
The template will now work without any further edits, but can be customized to suit specific needs. Vast recommends keeping the template private to avoid making any private information publically known.
</Check>
We should now see the Vast.ai search page with the template selected. For those intending to use the Vast CLI, click More Options on the template and select 'Copy template hash'. We will use this in step 3.

</Step>
<Step title="Create The Endpoint">
Next we will create an Endpoint that any user can query for generation. This can be done through the Web UI or the Vast CLI. Here, we'll create an endpoint named 'vLLM-Qwen3-8B '.
<Tabs>
<Tab title="Web UI">
Navigate to the [Serverless Page](https://cloud.vast.ai/serverless/) and click Create Endpoint. A screen to create a new Endpoint will pop up, with default values already assigned. Our Endpoint will work with these default values, but you can change them to suit your needs.

* `endpoint_name`: The name of the Endpoint.
* `cold_mult`: The multiple of the current load that is used to predict the future load. For example, if we currently have 10 users, but expect there to be 20 in the near future, we can set cold\_mult = 2.&#x20;
* For LLMs, a good default is 2.
* `min_load`: The baseline amount of load (tokens / second for LLMs) we want the Endpoint to be able to handle.&#x20;
* For LLMs, a good default is 100.0
* `target_util`: The percentage of the Endpoint compute resources that we want to be in-use at any given time. A lower value allows for more slack, which means the Endpoint will be less likely to be overwhelmed if there is a sudden spike in usage.&#x20;
* For LLMs, a good default is 0.9
* `max_workers`: The maximum number of workers the Endpoint can have at any one time.
* `cold_workers`: The minimum number of workers kept "cold" (meaning stopped but fully loaded with the image) when the Endpoint has no load. Having cold workers available allows the Serverless system to seamlessly spin up more workers as when load increases.
Click Create, where you will be taken back to the Serverless page. After a few moments, the Endpoint will show up with the name 'vLLM-Qwen3-8B'.
</Tab>
<Tab title="Vast CLI">
If your machine is properly configured for the Vast CLI, you can run the following command:
```cli CLI Command theme={null}
vastai create endpoint --endpoint_name "vLLM-Qwen3-8B" --cold_mult 1.0 --min_load 100 --target_util 0.9 --max_workers 20 --cold_workers 5
```
* `endpoint_name`: The name you use to identify your Endpoint.
* `cold_mult`: The multiple of your current load that is used to predict your future load. For example if you currently have 10 users, but expect there to be 20 in the near future, you can set cold\_mult = 2.0.
* For LLMs, a good default is 2.0
* `min_load`: This is the baseline amount of load (tokens / second for LLMs) you want your Endpoint to be able to handle.&#x20;
* For LLMs, a good default is 100.0
* `target_util`: The percentage of your Endpoint compute resources that you want to be in-use at any given time. A lower value allows for more slack, which means your Endpoint will be less likely to be overwhelmed if there is a sudden spike in usage.&#x20;
* For LLMs, a good default is 0.9
* `max_workers`: The maximum number of workers your Endpoint can have at any one time.
* `cold_workers`: The minimum number of workers you want to keep "cold" (meaning stopped and fully loaded) when your Endpoint has no load.
A successful creation of the endpoint should return a `'success': True` as the output in the terminal.

</Step>
<Step title="Create a Workergroup">
Now that we have our Endpoint, we can create a Workergroup with the template we prepared in step 1.&#x20;
<Tabs>
<Tab title="Web UI">
From the Serverless page, click '+ Workergroup' under the Endpoint. Our custom vLLM (Serverless) template should already be selected. To confirm, click the Edit button and check that the `MODEL_NAME`environment variable is filled in.
For our simple setup, we can enter the following values:
* Cold Multiplier = 3
* Minimum Load = 1
* Target Utilization = 0.9
* Workergroup Name = 'Workergroup'

After entering the values, click Create, where you will be taken back to the Serverless page. After a moment, the Workergroup will be created under the 'vLLM-Qwen3-8B' Endpoint.
</Tab>
<Tab title="Vast CLI">
Run the following command to create your Workergroup:
```sh CLI Command theme={null}
vastai create workergroup --endpoint_name "vLLM-DeepSeek" --template_hash "$TEMPLATE_HASH" --test_workers 5
```
`endpoint_name`: The name of the Endpoint.
`template_hash`: The hash code of our custom vLLM (Serverless) template.
`test_workers`: The minimum number of workers to create while initializing the Workergroup. This allows the Workergroup to get performance estimates before serving the Endpoint, and also creates workers which are fully loaded and "stopped" (aka "cold").
<Warning>
You will need to replace "\$TEMPLATE\_HASH" with the template hash copied from step 1.

<Step title="Getting The First Ready Worker">
Now that we have created both the Endpoint and the Workergroup, all that is left to do is await for the first "Ready" worker. We can see the status of the workers in the Serverless section of the Vast.ai console. The workers will automatically download the Qwen3-8B model defined in the template, but it will take time to fully initialize. The worker is loaded and benchmarked when the `Curr. Performance` value is non-zero.
When a worker has finished benchmarking, the worker's status in the Workergroup will become Ready. We are now able to get a successful /route/ call to the Workergroup and send it requests!

</Steps>
We have now successfully created a vLLM + Qwen3-8B Serverless Engine! It is ready to receive user requests and will automatically scale up or down to meet the request demand. In this next section, we will setup a client to test the serverless engine, and learn how to use the core serverless endpoints along the way.
***
# Using the Serverless Engine
To fully understand this section, it is recommended to read the [PyWorker Overview](/documentation/serverless/overview). The overview shows how all the pieces related to the serverless engine work together.
The Vast vLLM (Serverless) template we used in the last section already has a client (client.py) written for it. To use this client, we must run commands in a terminal, since there is no UI available for this section. The client, along with all other files the GPU worker is cloning during initialization, can be found in the [Vast.ai Github repo](https://github.com/vast-ai/pyworker/tree/main). For this section, simply clone the entire repo using:
&#x20;`git clone https://github.com/vast-ai/pyworker.git`
As the User, we want all the files under 'User' to be in our file system. The GPU workers that the system initializes will have the files and entities under 'GPU Worker'.
<Frame caption="Files and Entities for the user and GPU worker">

</Frame>
## API Keys
Upon creation of a Serverless endpoint group, the group will obtain a special API key specifically for Serverless. This key is unique to an account, and will be used for all calls to the Serverless engine. This key is different from a standard Vast.ai API key and only works with Serverless endpoint groups. &#x20;
### Where to find a Serverless API key:
Use the Vast CLI to find a Serverless API key.
```cli CLI Command theme={null}
vastai show endpoints
```
The `show endpoints` command will return a JSON blob like this:
```javascript Javascript icon="js" theme={null}
{
"api_key": "952laufhuefiu2he72yhewikhf28732873827uifdhfiuh2ifh72hs80a8s728c699s9",
"cold_mult": 2.0,
"cold_workers": 3,
"created_at": 1755115734.0841732,
"endpoint_name": "vLLM-Qwen3-8B",
"endpoint_state": "active",
"id": 1234,
"max_workers": 5,
"min_load": 10.0,
"target_util": 0.9,
"user_id": 123456
}
```
<Accordion title="Install the TLS certificate \[Optional]">
## Install the TLS certificate \[Optional]
All of Vast.ai's pre-made Serverless templates use SSL by default. If you want to disable it, you can add `-e USE_SSL=false` to the Docker options in your copy of the template. The Serverless Engine will automatically adjust the instance URL to enable or disable SSL as needed.
1. Download Vast AI's certificate from [here](https://console.vast.ai/static/jvastai_root.cer).
2. In the Python environment where you're running the client script, execute the following command: `python3 -m certifi`
3. The command in step 2 will print the path to a file where certificates are stored. Append Vast AI's certificate to that file using the following command: `cat jvastai_root.cer >> PATH/TO/CERT/STORE`
4. You may need to run the above command with `sudo` if you are not running Python in a virtual environment.
<Note>
This process only adds Vast AI's TLS certificate as a trusted certificate for Python clients.&#x20;
For non-Python clients, you'll need to add the certificate to the trusted certificates for that specific client. If you encounter any issues, feel free to contact us on support chat for assistance.
</Note>
</Accordion>
<Steps>
<Step title="Running client.py">
In client.py, we are first sending a POST request to the [`/route/`](/documentation/serverless/route) endpoint. This sends a request to the serverless engine asking for a ready worker, with a payload that looks like:
```javascript Javascript icon="js" theme={null}
route_payload = {
"endpoint": "endpoint_name",
"api_key": "your_serverless_api_key",
"cost": COST,
}
```
The `cost` input here tells the serverless engine how much workload to expect for this request, and is *not&#x20;*&#x72;elated to credits on a Vast.ai account. The engine will reply with a valid worker address, where client.py then calls the `/v1/completions` endpoint with the authentication data returned by the serverless engine and the user's model input text as the payload.
```json JSON theme={null}
{
"auth_data": {
"cost": 256.0,
"endpoint": "endpoint_name",
"reqnum": "req_num",
"signature": "signature",
"url": "worker_address"
},
"payload": {
"input": {
"model": "Qwen/Qwen3-8B",
"prompt": "The capital of USA is",
"temperature": 0.7,
"max_tokens": 256,
"top_k": 20,
"top_p": 0.4,
"stream": false}
}
}
}
```
The worker hosting the Qwen3-8B model will return the model results to the client, and print them to the user.&#x20;
To quickly run a basic test of the serverless engine with vLLM, navigate to the `pyworker` directory and run:
```none CLI Command theme={null}
pip install -r requirements.txt && \
python3 -m workers.openai.client -k "$YOUR_USER_API_KEY" -e "vLLM-Qwen3-8B" --model "Qwen/Qwen3-8B" --completion
```
<Warning>
client.py is configured to work with a vast.ai API key, not a Serverless API key. Make sure to set the `API_KEY` variable in your environment, or replace it by pasting in your actual key. You only need to install the requirements.txt file on the first run.
</Warning>
This should result in a "Ready" worker with the Qwen3-8B model printing a Completion Demo to your terminal window. If we enter the same command without --completion, you will see all of the test modes vLLM has. Because we are testing with Qwen3-8B, all test modes will provide a response (not all LLMs are equipped to use tools).
```bash CLI Command theme={null}
python3 -m workers.openai.client -k "$YOUR_USER_API_KEY" -e "vLLM-Qwen3-8B" --model "Qwen/Qwen3-8B"
Please specify exactly one test mode:
--completion : Test completions endpoint
--chat : Test chat completions endpoint (non-streaming)
--chat-stream : Test chat completions endpoint with streaming
--tools : Test function calling with ls tool (non-streaming)
--interactive : Start interactive streaming chat session
```
</Step>
<Step title="Monitoring Groups">
There are several endpoints we can use to monitor the status of the serverless engine. To fetch all [Endpoint logs](/documentation/serverless/logs), run the following cURL command:
```bash Bash theme={null}
curl https://run.vast.ai/get_endpoint_logs/ \
-X POST \
-d '{"endpoint" : "vLLM-Qwen3-8B", "api_key" : "$YOUR_SERVERLESS_API_KEY"}' \
-H 'Content-Type: application/json'
```
Similarily, to fetch all [Workergroup logs](/documentation/serverless/logs), execute:
```bash Bash theme={null}
curl https://run.vast.ai/get_workergroup_logs/ \
-X POST \
-d '{"id" : WORKERGROUP_ID, "api_key" : "$YOUR_SERVERLESS_API_KEY"}' \
-H 'Content-Type: application/json'
```
All Endpoints and Workergroups continuously track their performance over time, which is sent to the serverless engine as metrics. To see Workergroup metrics, run the following:
```bash Bash theme={null}
curl -X POST "https://console.vast.ai/api/v0/serverless/metrics/" \
-H "Content-Type: application/json" \
-d '{
"start_date": 1749672382.157,
"end_date": 1749680792.188,
"step": 500,
"type": "autogroup",
"metrics": [
"capacity",
"curload",
"nworkers",
"nrdy_workers_",
"reliable",
"reqrate",
"totreqs",
"perf",
"nrdy_soon_workers_",
"model_disk_usage",
"reqs_working"
],
"resource_id": '"${workergroup_id}"'
}'
```
These metrics are displayed in a Workergroup's UI page.
</Step>
<Step title="Load Testing">
In the Github repo that we cloned earlier, there is a load testing script called `workers/openai/test_load.py`. The *-n&#x20;*&#x66;lag indicates the total number of requests to send to the serverless engine, and the *-rps&#x20;*&#x66;lag indicates the rate (requests/second). The script will print out statistics that show metrics like:
* Total requests currently being generated
* Number of successful generations
* Number of errors
* Total number of workers used during the test
To run this script, make sure the python packages from `requirements.txt` are installed, and execute the following command:
```sh SH theme={null}
python3 -m workers.openai.test_load -n 100 -rps 1 -k "$YOUR_USER_API_KEY" -e "vLLM-Qwen3-8B" --model "Qwen/Qwen3-8B"
```
</Step>
</Steps>
This is everything you need to start, test, and monitor a vLLM + Qwen3-8B Serverless engine! There are other Vast pre-made [serverless templates](/documentation/templates/quickstart), like the ComfyUI Image Generation model, that can be setup in a similar fashion.&#x20;

# Inside a Serverless GPU
Source: https://docs.vast.ai/documentation/serverless/inside-a-serverless-gpu
Learn about the components of a Serverless GPU instance - the core ML model, model server code, and PyWorker server code.
All GPU instances on Vast Serverless contain three parts:
1. The core ML model.
2. The model server code that handles requests and inferences the ML model.
3. The [PyWorker](/documentation/serverless/overview) server code that wraps the ML model, which formats incoming HTTP requests into a compatible format for the model server.

The term 'Backend' refers to the machine learning model itself, and the supplementary code used to make its inference work.
On Vast Serverless, the only way to access the ML model is through the PyWorker that wraps it. This allows the PyWorker to report accurate metrics to the serverless system so it can size the number of GPU instances appropriatley.&#x20;
## Backend Configuration
Once a User has connected to a GPU Instance over Vast, the backend will start its own launch script. The launch script will:
* Setup a log file.
* Start a webserver to communicate with the ML model and PyWorker.
* Set environment variables.
* Launch the PyWorker and create a directory for it.
* Monitor the webserver and PyWorker processes.
After launch, the PyWorker acts as an inference API server façade, receiving HTTP requests, parsing them, and turning them into internal calls. &#x20;
The 'Model Server' icon in the image above represents the inference runtime. This piece loads the model, exposes an interface, performs the model forward pass, and returns the resulting tensors to the PyWorker.
## Adding Endpoints
To add an endpoint to an existing backend, follow the instructions in the [PyWorker Extension Guide](/documentation/serverless/creating-new-pyworkers). This guide can also be used to write new backends.
## Authentication
The authentication information returned by [https://run.vast.ai/route/ ](/documentation/serverless/route)must be included in the request JSON to the PyWorker, but will be filtered out before forwarding to the model server. For example, a PyWorker expects to receive auth data in the request:
```json JSON icon="js" theme={null}
{
"auth_data": {
"signature": "a_base64_encoded_signature_string_from_route_endpoint",
"cost": 256,
"endpoint": "Your-Endpoint-Name",
"reqnum": 1234567890,
"url": "http://worker-ip-address:port"
},
"payload": {
"inputs": "What is the answer to the universe?",
"parameters": {
"max_new_tokens": 256,
"temperature": 0.7,
"top_p": 0.9,
"do_sample": true
}
}
}
```
Once authenticated, the PyWorker will forward the following to the model server:
```json JSON icon="js" theme={null}
{
"inputs": "What is the answer to the universe?",
"parameters": {
"max_new_tokens": 256,
"temperature": 0.7,
"top_p": 0.9,
"do_sample": true
}
}
```
When the Serverless system returns an instance address from the `/route/` endpoint, it provides a unique signature with your request. The authentication server verifies this signature to ensure that only authorized clients can send requests to your server.

# Logs
Source: https://docs.vast.ai/documentation/serverless/logs
Learn how to fetch and analyze logs from Vast.ai Serverless endpoints and worker groups. Understand the log levels, how to use cURL to fetch logs, and how to interpret the logs for debugging and performance monitoring.
Both Endpoints and Worker Groups keep logs that can be fetched by using the `/get_endpoint_logs/` and `/get_autogroup_logs/` endpoints, respectively.
Endpoint logs relate to managing instances, and Worker Group logs relate to searching for offers to create instances from, as well as calls to create instances using the offers.&#x20;
For both types of groups, there are four levels of logs with decreasing levels of detail: **debug**, **trace**, **info0**, and **info1**.
<Warning>
Each log level has a fixed size, and once it is full, the log is wiped and overwritten with new log messages. It is good practice to check these regularly while debugging.
</Warning>
# POST [https://run.vast.ai/get\_endpoint\_logs/](https://run.vast.ai/get_endpoint_logs/)
## Inputs

# Overview
Source: https://docs.vast.ai/documentation/serverless/overview
Learn about Vast.ai's Serverless system - the Vast PyWorker, integration with model instances, and creating custom backends.
The Vast PyWorker is a Python web server designed to run alongside a machine learning model instance, providing serverless compatibility. It serves as the primary entry point for API requests, forwarding them to the model's API hosted on the same instance. Additionally, it monitors performance metrics and estimates current workload, reporting these metrics to the serverless system.
<Note>
All of Vast's serverless templates use the Vast PyWorker. If you are using a recommended serverless template from Vast, the PyWorker is *already* integrated with the template and will automatically startup when a \{\{Worker\_Group}} is created.&#x20;
</Note>

In the diagram's example, a user's client is attempting to infer from a machine learning model. With Vast's Serverless setup, the client:
1. Sends a [`/route/`](/documentation/serverless/route) POST request to the serverless system. This asks the system for a GPU instance to send the inference request.
2. The serverless system selects a ready and available worker instance from the user's endpoint and replies with a JSON object containing the URL of the selected instance.
3. The client then constructs a new POST request with it's payload, authentication data, and the URL of the worker instance. This is sent to the worker.
4. The PyWorker running on that specific instance validates the request and extracts the payload. It then sends the payload to the model inference server, which runs on the same instance as the PyWorker.
5. The model generates it's output and returns the result to the PyWorker.
6. The PyWorker formats the model's response as needed, and sends the response back to the client.&#x20;
7. Independently and concurrently, the PyWorker periodically sends it's operational metrics to the serverless system, which is used to make scaling decisions.
The [Vast PyWorker repository](https://github.com/vast-ai/pyworker/) gives examples that are useful for learning how to create a custom PyWorker for your custom template and integrate with Vast’s Serverless system. Even with a custom PyWorker, the PyWorker code runs on your Vast instance, and we automate its installation and activation during instance creation. The graphic below shows how the files and entities for the Serverless system are organized.

## Integration with Model Instance
The Vast PyWorker wraps the backend code of the model instance you are running. The PyWorker calls the appropriate backend function when the PyWorker's corresponding API endpoint is invoked. For example, if you are running a text generation inference (TGI) server, your PyWorker might receive the following JSON body from a `/generate` endpoint:&#x20;
```json JSON icon="js" theme={null}
{
"auth_data": {
"signature": "a_base64_encoded_signature_string_from_route_endpoint",
"cost": 256,
"endpoint": "Your-TGI-Endpoint-Name",
"reqnum": 1234567890,
"url": "http://worker-ip-address:port"
},
"payload": {
"inputs": "What is the answer to the universe?",
"parameters": {
"max_new_tokens": 256,
"temperature": 0.7,
"top_p": 0.9,
"do_sample": true
}
}
}
```
When it receives this request, your PyWorker will internally send the following to the TGI model sever:
```json JSON icon="js" theme={null}
{
"inputs": "What is the answer to the universe?",
"parameters": {
"max_new_tokens": 256,
"temperature": 0.7,
"top_p": 0.9,
"do_sample": true
}
}
```
Your PyWorker would similarily receive the output result from the TGI server, and forward a formatted version to the client.
## Communication with Serverless
If you are building a custom PyWorker for your own use case, to be able to integrate with Vast's serverless system, each backend must:
* Send a message to the serverless system when the backend server is ready (e.g., after model installation).
* Periodically send performance metrics to the serverless system to optimize usage and performance.
* Report any errors to the serverless system.
For example implementations, reference the [Vast PyWorker repository](https://github.com/vast-ai/pyworker/).
## Creating a Custom Backend
If you want to create your own backend and learn how to integrate with the serverless system, please refer to the following guides:&#x20;
* [Creating New PyWorkers](/documentation/serverless/creating-new-pyworkers)
## Vast Supported Backends
Vast has pre-made templates for popular models such as [Text-Generation-Inference](/documentation/serverless/text-generation-inference-tgi)
and [Comfy UI](/documentation/serverless/comfy-ui). These templates allow you to use these models in API mode, automatically handling performance and error tracking, making them compatible with Vast Serverless with no additional code required.
To get started with Vast-supported backends, see the [Inside a Severless GPU](/documentation/serverless/inside-a-serverless-gpu) guide.
# Performance Testing
Source: https://docs.vast.ai/documentation/serverless/performance-testing
Learn about the performance testing process in Vast.ai Serverless. Understand how the test measures LLM and image generation capabilities, how it translates pixel generation to tokens, and how it normalizes performance across different GPUs.
When the serverless system recruits a GPU for a \{\{Worker\_Group}}, the PyWorker on the GPU instance starts by conducting a performance test to assess the GPU's maximum capabilities.
### LLMs
For LLMs, this test measures the maximum tokens per second that can be generated across concurrent batches.&#x20;
### Image Generation
For image generation, the model is generating pixels, which does not directly translate to tokens. To translate pixel generation to tokens, the test counts the number of 512x512 pixel grids required to cover the image resolution, considering each grid as equivalent to 175 tokens.&#x20;
This value is added on top of a constant overhead token value of 85. Based on the number of diffusion steps performed, the value is adjusted to accomodate for the request time.
The value is then normalized so that a system running Flux on a 4090 GPU achieves a standardized performance rating of 200 tokens per second.
***
These performance tests may take several minutes to complete, depending on the machine's specifications. Progress can be monitored through the instance logs. Once the test is completed, the results are saved. If the instance is rebooted, the saved results will be loaded, and the test will not run again.
For more details on the full implementation, visit the [Vast PyWorker repository](https://github.com/vast-ai/pyworker/) and reference `backend.py` in the `lib/` folder of the PyWorker.
# Pricing
Source: https://docs.vast.ai/documentation/serverless/pricing
Learn how Vast.ai Serverless pricing works - GPU recruitment, endpoint suspension, and stopping.
Vast.ai Serverless offers pay-as-you-go pricing for all workloads at the same rates as Vast.ai's non-Serverless GPU instances. Each instance accrues cost on a per second basis.
This guide explains how pricing works.
## GPU Recruitment
As the Serverless engine takes requests, it will automatically scale its number of workers up or down depending on the incoming and forecasted demand. When scaling up,
the engine searches over the Vast.ai marketplace for GPU instances that offer the best performance / price ratio. Once determined, the GPU instance(s) is recruited into
the Serverless engine, and its cost (\$/hr) is added to the running sum of all GPU instances running on your Serverless engine.&#x20;
As the request demand falls off, the engine will remove GPU instance(s) and your credit account immediatley stops being charged for those corresponding instance(s).
Visit the [Billing Help](/documentation/reference/billing#ugwiY) page to see details on GPU instance costs.
## Suspending an Endpoint
By suspending an Endpoint, the Endpoint will no longer recruit any new GPU instances, but will continue to use the instances it currently has. This is a way to cap the
number of instances an Endpoint can manage, and therefore limit costs.&#x20;
## Stopping an Endpoint
Stopping an Endpoint will pause the recruitment of GPU instances, and put the existing instances into the "Stopped" state, preventing any work from being sent to
the Endpoint group. The instances will still charge the small storage cost, but active rental and bandwidth costs will not be charged to the user account.&#x20;
## Billing by Instance State
The specific charges depend on the instance's state:
| State | GPU compute | Storage | Bandwidth in | Bandwidth out |
| -------- | ----------- | ------- | ------------ | ------------- |
| Ready | Billed | Billed | Billed | Billed |
| Loading | Billed | Billed | Billed | Billed |
| Creating | Not billed | Billed | Billed | Billed |
| Inactive | Not billed | Billed | Billed | Billed |
GPU compute refers to the per-second GPU rental charges. See the [Billing Help](/documentation/reference/billing#ugwiY) page for rate details.
# Route
Source: https://docs.vast.ai/documentation/serverless/route
Learn how to use the /route/ endpoint to retrieve a GPU instance address within your Endpoint. Understand the inputs, outputs, and examples for using the endpoint.
The `/route/` endpoint calls on the serverless engine to retrieve a GPU instance address within your Endpoint.
# POST [https://run.vast.ai/route/](https://run.vast.ai/route/)
## Inputs
* `endpoint`(string): Name of the Endpoint.
* `api_key`(string): The Vast API key associated with the account that controls the Endpoint. The key can also be placed in the header as an Authorization: Bearer.
* `cost`(float): The estimated compute resources for the request. The units of this cost are defined by the PyWorker. The serverless engine uses the cost as an estimate of the request's workload, and can scale GPU instances to ensure the Endpoint has the proper compute capacity.
```json JSON icon="js" theme={null}
{
"endpoint": "YOUR_ENDPOINT_NAME",
"api_key": "YOUR_VAST_API_KEY",
"cost": 242.0
}
```
## Outputs
### On Successful Worker Return
* `url`(string): The address of the worker instance to send the request to.
* `reqnum`(int): The request number corresponding to this worker instance. Note that workers expect to receive requests in approximately the same order as these reqnums, but some flexibility is allowed due to potential out-of-order requests caused by concurrency or small delays on the proxy server.
* `signature`(string): The signature is a cryptographic string that authenticates the url, cost, and reqnum fields in the response, proving they originated from the server. Clients can use this signature, along with the server's public key, to verify that these specific details have not been tampered with.
* `endpoint`(string): Same as the input parameter.
* `cost`(float): Same as the input parameter.
* `__request_id `(string): The \_\_request\_id is a unique string identifier generated by the server for each individual API request it receives. This ID is created at the start of processing the request and included in the response, allowing for distinct tracking and logging of every transaction.
```json JSON icon="js" theme={null}
{
"endpoint": "YOUR_ENDPOINT_NAME",
"url": "http://192.168.1.10:8000",
"cost": 242.0,
"reqnum": 12345,
"signature": "a1b2c3d4e5f60708090a0b0c0d0e0f101112131415161718191a1b1c1d1e1f202122232425262728292a2b2c2d2e2f303132333435363738393a3b3c3d3e3f40",
"__request_id": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
}
```
### On Failure to Find Ready Worker
* `endpoint`: Same as the input parameter to `/route/`.
* `status`: The breakdown of workers in your endpoint group by status.
## Example: Hitting route with cURL
```curl Curl icon="cube" theme={null}
curl --location 'https://run.vast.ai/route/' \
--header 'Accept: application/json' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer YOUR_TOKEN_HERE' \
--data '{
"endpoint": "your_endpoint_name",
"cost": 100
}'
```
# Serverless Parameters
Source: https://docs.vast.ai/documentation/serverless/serverless-parameters
Learn about the parameters that can be configured for Vast.ai Serverless endpoints and worker groups.
The Vast.ai Serverless system has parameters that allow control over the scaling behavior.&#x20;
# Endpoint Parameters
## cold\_mult
A multiplier applied to your target capacity for longer-term planning (1+ hours). This parameter controls how much extra capacity the serverless engine will plan for in the future compared to immediate needs. For example, if your current target capacity is 100 tokens/sec and cold\_mult is 2.0, the system will plan to have capacity for 200 tokens/sec for longer-term scenarios.
This helps ensure your endpoint has sufficient "cold" (stopped but ready) workers available to handle future load spikes without delay. A higher value means more aggressive capacity planning and better preparedness for sudden traffic increases, while a lower value reduces costs from maintaining stopped instances.
If not specified during endpoint creation, the default value is 2.5.
## cold\_workers
The minimum number of workers that must be kept in a "ready quick" state before the serverless engine is allowed to destroy any workers. A worker is considered "ready quick" if it's either:
\- Actively serving (status = "idle" with model loaded)
\- Stopped but ready (status = "stopped" with model loaded)
Cold workers are not shut-down, they are stopped but have the model fully loaded. This means they can start serving requests very quickly (seconds) without having to re-download the model or benchmark the GPU performance.
If not specified during endpoint creation, the default value is 5.
## max\_workers
A hard upper limit on the total number of worker instances (ready, stopped, loading, etc.) that your endpoint can have at any given time.
If not specified during endpoint creation, the default value is 20.
## min\_load
A minimum baseline load (measured in tokens/second for LLMs) that the serverless system will assume your Endpoint needs to handle, regardless of actual measured traffic. This acts as a "floor" for load predictions across all time horizons (1 second to 24+ hours), ensuring your endpoint maintains minimum capacity even during periods of zero or very low traffic.
For example, if your min\_load is set to 100 tokens/second, but your endpoint currently has zero traffic, the serverless system will still plan capacity as if you need to handle at least 100 tokens/second. This prevents the endpoint from scaling down to zero capacity and ensures you're always ready for incoming requests.
If not specified during endpoint creation, the default value is 10.
## target\_util
The target utilization ratio determines how much spare capacity (headroom) the serverless system maintains. For example, if your predicted load is 900 tokens/second and target\_util is 0.9, the serverless engine will plan for 1000 tokens/second of capacity (900 ÷ 0.9 = 1000), leaving 100 tokens/second (11%) as buffer for traffic spikes.
A lower target\_util means more headroom:
\- target\_util = 0.9 → 11.1% spare capacity relative to load
\- target\_util = 0.8 → 25% spare capacity relative to load
\- target\_util = 0.5 → 100% spare capacity relative to load
\- target\_util = 0.4 → 150% spare capacity relative to load
If not specified during endpoint creation, the default value is 0.9.
# Workergroup Parameters
The following parameters can be specified specifically for a Workergroup and override Endpoint parameters. The Endpoint parameters will continue to apply for other Workergroups contained in it, unless specifically set.&#x20;
* min\_load
* target\_util
* cold\_mult
The parameters below are specific to only Workergroups, not Endpoints.
## gpu\_ram
The amount of GPU memory (VRAM) in gigabytes that your model or workload requires to run. This parameter tells the serverless engine how much GPU memory your model needs.
If not specified during workergroup creation, the default value is 24.
## launch\_args
A command-line style string containing additional parameters for instance creation that will be parsed and applied when the serverless engine creates new workers. This allows you to customize instance configuration beyond what's specified in templates.
There is no default value for launch\_args.
## search\_params
A query string, list, or dictionary that specifies the hardware and performance criteria for filtering GPU offers in the vast.ai marketplace. It uses a simple query syntax to define requirements for the machines that your Workergroup will consider when searching for workers to create.
Example:
```python icon="python" Python theme={null}
{"verified": {"eq": true}, "rentable": {"eq": true}, "rented": {"eq": false}}
```
There is no default value for search\_params. To see all available search filters, see the CLI docs [here](https://docs.vast.ai/cli/commands).
## template\_hash
A unique hexadecimal identifier that references a pre-configured template containing all the configuration needed to create instances. Templates are comprehensive specifications that include the Docker image, environment variables, onstart scripts, resource requirements, and other deployment settings.
There is no default value for template\_hash.
## template\_id
A numeric (integer) identifier that uniquely references a template in the Vast.ai database. This is an alternative way to reference the same template that `template_hash` points to, but using the template's database primary key instead of its hash string.
There is no default value for template\_id.
## test\_workers
The number of different physical machines that a Workergroup should test during its initial "exploration" phase to gather performance data before transitioning to normal demand-based scaling. The Worker Group remains in "exploring" mode until it has successfully tested at least `floor(test_workers / 2)` machines.
If not specified during workergroup creation, the default value is 3.
# Text Generation Inference (TGI)
Source: https://docs.vast.ai/documentation/serverless/text-generation-inference-tgi
Learn how to use Text Generation Inference (TGI) with Vast.ai Serverless for text generation models.
The [Text Generation Inference serverless template](https://cloud.vast.ai?ref_id=140778\&template_id=e97e6c337efd5562ad419cdb392981a4) can be used to infer LLMs on Vast GPU instances. This page documents required environment variables and endpoints to get started.
A full PyWorker and Client implementation can be found [here](https://github.com/vast-ai/pyworker/tree/main).

* `signature`(string): A cryptographic string that authenticates the url, cost, and reqnum fields in the response, proving they originated from the server. Clients can use this signature, along with the server's public key, to verify that these specific details have not been tampered with.
* `cost`(float): The estimated compute resources for the request. The units of this cost are defined by the PyWorker.&#x20;
* `endpoint`(string): Name of the Endpoint.
* `reqnum`(int): The request number corresponding to this worker instance. Note that workers expect to receive requests in approximately the same order as these reqnums, but some flexibility is allowed due to potential out-of-order requests caused by concurrency or small delays on the proxy server.
* `url`(string): The address of the worker instance to send the request to.
Payload:
* `inputs`(string): The prompt message to be used as the input for the LLM.
* Parameters:
* `max_new_tokens`(int): The maximum number of tokens the model will generate for the response to the input.
```json JSON icon="js" theme={null}
{
"auth_data": {
"signature": "a_base64_encoded_signature_string_from_route_endpoint",
"cost": 256,
"endpoint": "Your-TGI-Endpoint-Name",
"reqnum": 1234567890,
"url": "http://worker-ip-address:port"
},
"payload": {
"inputs": "What is the answer to the universe?",
"parameters": {
"max_new_tokens": 256
}
}
}
```
Depending on the model being used, other parameters like 'temperature' or 'top\_p' may be supported. Passing in these values in `parameters` will forward the values to the model, but they are *not* required.
### Outputs
* `generated_text`(string): The model response to the input prompt.
```json JSON icon="js" theme={null}
[
{
"generated_text": "The model's response..."
}
]
```
## **/generate\_stream**/&#x20;
Generates and streams the LLM's response token by token.
### Inputs
`/generate_stream/` takes the same inputs as `/generate/`:
Auth\_data:
* `signature`(string): A cryptographic string that authenticates the url, cost, and reqnum fields in the response, proving they originated from the server. Clients can use this signature, along with the server's public key, to verify that these specific details have not been tampered with.
* `cost`(float): The estimated compute resources for the request. The units of this cost are defined by the PyWorker.&#x20;
* `endpoint`(string): Name of the Endpoint.
* `reqnum`(int): The request number corresponding to this worker instance. Note that workers expect to receive requests in approximately the same order as these reqnums, but some flexibility is allowed due to potential out-of-order requests caused by concurrency or small delays on the proxy server.
* `url`(string): The address of the worker instance to send the request to.
Payload:
* `inputs`(string): The prompt message to be used as the input for the LLM.
* Parameters:
* `max_new_tokens`(int): The maximum number of tokens the model will generate for the response to the input.
<Note>
The `max_new_tokens` parameter, rather than the prompt size, impacts performance. For example, if an instance is benchmarked to process 100 tokens per second, a request with `max_new_tokens = 200` will take approximately 2 seconds to complete.
</Note>
```json JSON icon="js" theme={null}
{
"auth_data": {

},
"payload": {
"inputs": "What is the answer to the universe?",
"parameters": {
"max_new_tokens": 256
}
}
}
```
### Outputs
`/generate_stream/` outputs are a stream of Server-Sent Events (SSE), which each event looking like:
```json JSON icon="js" theme={null}
{
"token": {
"id": 123, // Token ID
"text": "Hello", // The actual text of the token
"logprob": -0.12345, // Log probability of the token
"special": false // Whether it's a special token (e.g., EOS)
}
}

# vLLM
Source: https://docs.vast.ai/documentation/serverless/vllm
Learn how to use vLLM with Vast.ai Serverless for large language model inference.
The vLLM Serverless template can be used to infer LLMs on Vast GPU instances. This page documents required environment variables and endpoints to get started.
A full PyWorker and Client implementation can be found [here](https://github.com/vast-ai/pyworker/tree/main), which implements the endpoints below.
# Environment Variables
* `HF_TOKEN`(string): HuggingFace API token with read permissions, used to download gated models. Read more about HuggingFace tokens [here](https://huggingface.co/docs/hub/en/security-tokens). This token should be added to your Vast user account's environment variables. The [Getting Started](/documentation/serverless/getting-started-with-serverless) guide shows this in step 1.
* `MODEL_NAME`(string): Name of the model to be used for inference. Supported HuggingFace models are shown [here.](https://huggingface.co/docs/text-generation-inference/en/supported_models)
* `VLLM_ARGS`(string): vLLM specific arguments that are already pre-set in the template.&#x20;
<Warning>
Some models on HuggingFace require the user to accept the terms and conditions on their HuggingFace account before using. For such models, this must be done first before using it with a Vast template.
</Warning>
# Endpoints
## /v1/completions/&#x20;
This endpoint generates a text completion that attempts to match any context or pattern provided in a given prompt. Provide a text prompt, and the model returns the predicted continuation. This endpoint is best suited for single-turn tasks, whereas the /v1/chat/completions endpoint is optimized for multi-turn conversational scenarios.
### Inputs
auth\_data:
* `signature`(string): A cryptographic string that authenticates the url, cost, and reqnum fields in the response, proving they originated from the server. Clients can use this signature, along with the server's public key, to verify that these specific details have not been tampered with.
* `cost`(float): The estimated compute resources for the request. The units of this cost are defined by the PyWorker.&#x20;
* `endpoint`(string): Name of the Endpoint.
* `reqnum`(int): The request number corresponding to this worker instance. Note that workers expect to receive requests in approximately the same order as these reqnums, but some flexibility is allowed due to potential out-of-order requests caused by concurrency or small delays on the proxy server.
* `url`(string): The address of the worker instance to send the request to.
payload:
* `input`:
* `model`(string): The specific identifier of the model to be used for generating the text completion.
* `prompt`(optional, string): The input text that the model will use as a starting point to generate a response. Default is "Hello".
* `max_tokens`(optional, int): The maximum number of tokens the model will generate for the response to the input. Default is 256.
* `temperature`(optional, float): A value between 0 and 2 that controls the randomness of the output. Higher values result in more creative and less predictable responses, while lower values make the output more deterministic. Default is 0.7.
* `top_k`(optional, int): An integer that restricts the model to sampling from the k most likely tokens at each step of the generation process. Default is 20.
* `top_p`(optional, float): A float between 0 and 1 that controls nucleus sampling. The model considers only the most probable tokens whose cumulative probability exceeds p. Default is 0.4.
* `stream`(optional, bool): A boolean flag that determines the response format. If true, the server will send back a stream of token-by-token events as they are generated. If false, it will send the full completion in a single response after it's finished. Default is false.
```json JSON icon="js" theme={null}
{
"auth_data": {
"signature": "a_base64_encoded_signature_string_from_route_endpoint",
"cost": 256,
"endpoint": "Your-Endpoint-Name",
"reqnum": 1234567890,
"url": "http://worker-ip-address:port"
},
"payload": {
"input": {
"prompt": "The capital of the United States is",
"model": "Qwen/Qwen3-8B",
"max_tokens": 256,
"temperature": 0.7,
"top_k": 20,
"top_p": 0.4,
"stream": false
}
}
}
```
Depending on the model being used, other parameters like 'temperature' or 'top\_p' may be supported. Passing in these values in `parameters` will forward the values to the model, but they are *not* required. All parameters can be found in the `CompletionConfig` class in client.py.
### Outputs
* `id`(string): A unique identifier for the completion request.
* `object`(string): The type of object returned. For completions, this is always `text_completion`.
* `created`(int): The Unix timestamp (in seconds) of when the completion was created.
* `model`(string): The name of the model that generated the response.
* `choices`:
* `index`(int): The index of the choice in the list (e.g., 0 for the first choice).
* `text`(string): The generated text for this completion choice.
* `logprobs`(object): This field is null unless you requested log probabilities. If requested, it contains the log probabilities of the generated tokens.
* `finish_reason`(string): The reason the model stopped generating text. Common values include length (reached max\_tokens), stop (encountered a stop sequence), or tool\_calls.
* `stop_reason`(string): Provides a more specific reason for why the model stopped, often related to internal model logic. It can be null if not applicable.
* `prompt_logprobs`(object): Similar to logprobs, but for the tokens in the initial prompt. It is null unless specifically requested.
* `usage`:
* `prompt_tokens`(int): The number of tokens in the input prompt.
* `total_tokens`(int): The total number of tokens used in the request (prompt + completion).
* `completion_tokens`(int): The number of tokens in the generated completion.
* `prompt_tokens_details`(object): Provides a more detailed breakdown of prompt tokens. It is null unless requested.
* `kv_transfer_params`(object): An extension field (outside the official OpenAI spec) that carries all the metadata you need to reuse or move around the model’s key/value (KV) cache instead of recomputing it on every call.

```
## **/v1**/chat/completions/&#x20;
This endpoint generates a model response for a given conversational history. Unlike the /v1/completions/ endpoint, which is designed to continue a single text prompt, the chat endpoint excels at multi-turn dialogues. By providing a sequence of messages, each with a designated role (system, user, or assistant), you can simulate a conversation, and the model will generate the next appropriate message from the assistant.
<Danger>
Not all LLMs will work with this endpoint. The model must be fine-tuned to understand messages and tools. The default model used in the Vast template will work.&#x20;
</Danger>
### Inputs
`auth_data`:
* `signature`(string): A cryptographic string that authenticates the url, cost, and reqnum fields in the response, proving they originated from the server. Clients can use this signature, along with the server's public key, to verify that these specific details have not been tampered with.
* `cost`(float): The estimated compute resources for the request. The units of this cost are defined by the PyWorker.&#x20;
* `endpoint`(string): Name of the Endpoint.
* `reqnum`(int): The request number corresponding to this worker instance. Note that workers expect to receive requests in approximately the same order as these reqnums, but some flexibility is allowed due to potential out-of-order requests caused by concurrency or small delays on the proxy server.
* `url`(string): The address of the worker instance to send the request to.
`payload`:
* `input`:
* `model`(string): The specific identifier of the model to be used for generating the text completion.
* `messages`(array): A list of message objects that form the conversation history.
* `role`(string): The role of the message author. Can be system, user, or assistant.
* `content`(string): The content of the message.
* `max_tokens`(optional, int): The maximum number of tokens the model will generate for the response to the input. Default is 256.
* `temperature`(optional, float): A value between 0 and 2 that controls the randomness of the output. Higher values result in more creative and less predictable responses, while lower values make the output more deterministic. Default is 0.7.
* `top_k`(optional, int): An integer that restricts the model to sampling from the k most likely tokens at each step of the generation process. Default is 20.
* `top_p`(optional, float): A float between 0 and 1 that controls nucleus sampling. The model considers only the most probable tokens whose cumulative probability exceeds p. Default is 0.4.
* `stream`(optional, bool): A boolean flag that determines the response format. If true, the server will send back a stream of token-by-token events as they are generated. If false, it will send the full completion in a single response after it's finished. Default is false.
* `tools`(optional, List\[Dict\[str, Any]]): A list of function definitions that the model can call to perform external actions. When a relevant tool is detected in the user's prompt, the model can generate a JSON object with the function name and arguments to call. Your code can then execute this function and return the output to the model to continue the conversation.
* `tool_choice`(optional, string): This parameter controls how the model uses the functions provided in the tools list. It can be set to "none" to prevent the model from using any tools, "auto" to let the model decide when to call a function, or you can force the model to call a specific function by providing an object like \{"type": "function", "function": \{"name": "my\_function\_name"}}.
<Note>
The `max_tokens` parameter, rather than the `messages` size, impacts performance. For example, if an instance is benchmarked to process 100 tokens per second, a request with `max_tokens = 200` will take approximately 2 seconds to complete.

## Overview
Originally, the process of creating a team involved converting a user's personal account into a special team account. This legacy method has now been replaced with the ability to create separate team accounts.
### Reminders for Legacy Team Accounts
* **Irreversible Process**: Once a user account has been converted into a team account, the change is permanent and cannot be reversed.
* **Inheritance of Account Attributes**: The converted team account inherits all aspects of your existing personal account, including billing information, cloud services, and any other account settings.

This guide covers all the operations you'll need to manage your team after creation, including inviting members, managing roles, editing settings, and more.
## The Members Page
The Members page is the main hub for managing your team. Here you can view team members, assign roles, invite new members, and access team settings.
Here's an example of what a Members page looks like in the console:

Anyone with the proper permissions (currently **team\_write**) can send invitations to invite team members at any role level.
### Accepting Team Invitations
1. **Receiving the Invitation Email**: Invitees will receive an email containing a unique team invitation link.
2. **Completing the Joining Process**: Clicking the link will initiate a set of operations to add the invitee to the team. This may involve signing into the Vast.ai platform or creating an account if necessary.
3. **Confirmation of Membership**: Once the process is complete, the new member will be officially added to the team and will have access based on their role.
**Note:** If the recipient of the invitation does not have a Vast account, they will need to create one before being added to your Team.
### Best Practices for Invitations
* **Ensure Accurate Email Address**: Double-check the email address before sending invitations to avoid any miscommunication.
* **Communicate with Invitees**: Inform potential team members that they will be receiving an invitation and what steps they need to follow.
* **Follow-up on Pending Invitations**: Keep track of sent invitations and follow up with invitees who haven't joined yet. **Note:** Team Invitations will expire after **4 hours.**
## Managing Member Roles
You can change a member's role by clicking on the directional arrow next to their name and selecting a new role.

Every team comes with two default roles:
* **Manager**: Full access to team resources
* **Member**: Limited read access to most resources while still being able to rent instances
For detailed information about creating custom roles with specific permissions, see the [Teams Roles](/documentation/teams/teams-roles) documentation.

## Introduction
Vast.ai's Teams feature extends our powerful GPU compute services to collaborative environments. It allows multiple users to work together seamlessly in a shared space, managing serverless workers for AI Inference and GPU computing tasks collectively.
### Key Features:
* **Collaborative Environment**: Enable teams to work together in a shared space, managing resources and tasks collectively.
* **Resource Allocation & Management**: Team managers can manage access among team members, ensuring efficient use of GPU workers. (In the future, resource allocation will also be in play)
* **Consolidated Billing**: Simplifies the financial management by consolidating usage and billing across the team.
* **Performance Metrics & Access Controls**: Each team member can access shared metrics and logs, with custom access controls set by team owners.
## Getting Started with Teams
Ready to create your first team? Check out our [Team Creation guide](https://docs.vast.ai/teams-quickstart) for a step-by-step tutorial on creating a team, inviting members, and assigning roles.
## Creating Multiple Teams
Teams are created as separate accounts, allowing multiple teams to be created by a single user. Note: This feature is unavailble for Legacy Teams (accounts that were converted into teams directly). Each team operates independently, with its own members, roles, and permissions. Users can seamlessly switch between their personal and team accounts using the Context Switcher.
* **Independent Team Management:** Each team has its own and members and roles.
* **Shared Resources:** Each team shares resources such as instances, templates, machines, and certain settings with all team members.
* **Separate Billing & Credits:** Teams maintain their own separate balance/credit, billing information, and payment history, separate from personal accounts.
* **Easy Switching:** Users can navigate between personal and team accounts without affecting their workflow.
## Conclusion
The Teams feature at Vast.ai is designed to bring a new level of collaboration and efficiency to your GPU computing tasks. Additionally, by bringing together the power of our Autoscaling system with these collaborative tools, your team will be well-equipped to tackle all kinds of complex, dynamic workloads effectively.

Once there, you can create your **Team Name** and transfer some credit to your team during creation. You can also skip the credit transfer step and do it later from the [**Billing Page**](/documentation/reference/billing#a6bsE).
To add credit during team creation, select **Transfer my personal credits** checkbox, enter an amount, and then click **Create**.

The **Members** section is the main way that team owners and managers can interact with the Teams ecosystem. From here you can invite team members, create/manage team roles, remove team members, etc.
## Managing Team Roles
Every team comes with two default roles: manager and member.
Managers have full access to team resources, while members have limited read access to most resources while still being able to rent instances. [Learn more.](/documentation/teams/teams-roles)
To create a new role with your desired permissions, navigate to the **Roles** tab of the **Members** **Page**. Then you can name the role and choose the permission groups that the new role will have access to. Once you are satisfied, click **Generate** to create the new role.

Once you send the invitation, the user should get an email asking them to join your team. Upon clicking the link in the email they will be added as a member of your team.
**Note:** if the recipient of the invitation does not have a Vast account, they will need to create one before being added to your Team.
Once the invitee has joined your team, you should see them listed in the **Members** section.

## Using SSH Keys with Team Instances
If you are part of a **team** and want to connect to a **team’s instance** using SSH, simply add your key to your individual account keys. Here’s how it works depending on the type of instance:
🔹 VM Instances
* Your SSH key **must be added to your personal account before the VM is created**.
* When the VM is launched, all SSH keys in your account are automatically included for access a team instance.
🔹 Non-VM Instances
* You can either:
* **Add your SSH key directly to the instance**, or
* **Add your key to your personal account**, in which case it will be automatically applied to the team instance as well.

## What Are Team Roles?
Team roles in Vast.ai's platform are designed to streamline collaboration and enhance security by assigning specific permissions and access levels to different members of a team. These roles determine what actions a team member can perform and what data they can access within the team's shared workspace/context.
### Types of Team Roles
1. **Default Roles**: These are the standard roles with preset permissions, suitable for common team structures:
* *Owner*: Full access to all team resources, settings, and member management.
* *Manager*: All permissions of Team Owner apart from Team Deletion.
* *Member*: Has ability to view, create, and interact with instances, but no access to billing info, team management, autoscaler, machines, etc.
2. **Custom Roles**: Custom roles allow team managers to create roles with custom, tailored permissions via permission groups. This feature is particularly useful for teams with unique workflow requirements or specific security protocols.
For more information on Permission Groups and what they allow access to, [click here](/cli/installation).
### Creating Custom Roles
* **Accessing Role Management**: Custom roles can be created and managed through the **Roles** tab of the **Members** Page on the Vast.ai platform.
* **Defining Permissions**: When creating a custom role, you can select from a wide range of read/write permissions, such as instance creation, billing access, etc. This allows for precise control over what each role can and cannot do.
* **Assigning Custom Roles**: Once a custom role is created, it can be assigned to team members through the team management interface.
You can create roles either in the Vast CLI or on your team dashbaord if you have permission to create roles within your team (team\_write).

### Role Syntax
All team roles are created through the team dashboard using the role editor. You can also create roles through the Vast CLI by passing in a permissions JSON object that delegates what group of endpoints can be accessed.
Currently, the system only supports groups of endpoint categories, but soon it will be extended for further granularity.
The current activated scopes are as follows
* **misc**: Supports uncategorized operations like search offers, getting logs from various sources, etc
* **user\_read**: Allows the usage of obtaining basic user data like email, credits, etc. Essential for web usage.
* **user\_write**: Allows the ability to change account settings such as email, password, 2FA, etc.
* **instance\_read**: Grants ability to view instances, and certain read-only instance operations
* **instance\_write**: Grants access to instances and all relevant operations such as starting/stopping instances, cloud copy, reserving credits, etc
* **billing\_read**: Ability to view billing page and get billing information
* **billing\_write**: Ability to change billing page information
* **machine\_read**: Read access to machines owned by the team
* **machine\_write**: Ability to add/remove machines, and also edit machine settings
An example of a permissions json would look like this:
```text Text theme={null}
{
"api": {
"misc": {},
"user_read":{},
"instance_read": {},
"instance_write": {},
"team_read": {
"api.team.members": {}
}
}
}
```
In order to create a granular team roles you must either use the CLI or the API. In the above example, the only API under team\_read that the user would have access to would be viewing the list of team members.
For more information on Permissions [click here](/cli/installation).
### Best Practices for Using Team Roles
* **Clear Role Definitions**: Clearly define the responsibilities and permissions for each role to avoid confusion and ensure effective collaboration.
* **Use Custom Roles Judiciously**: Create custom roles when predefined roles do not meet your specific needs. Be mindful of the permissions assigned to ensure team security and efficiency.
### Conclusion
Team roles are a fundamental aspect of managing a secure environment for collaboration on the Vast.ai platform. By effectively utilizing predefined and custom roles, teams can ensure that each member has the appropriate level of access and control, fostering a productive and secure working environment.
# Advanced Setup
Source: https://docs.vast.ai/documentation/templates/advanced-setup
## Overview
This guide covers advanced customization techniques available on the Vast.ai platform. These features allow you to extend and enhance your templates beyond basic configuration.
For a complete reference of all template settings, see [Template Settings](/documentation/templates/template-settings).
For a step-by-step tutorial on creating your first template, see [Creating Templates](/documentation/templates/creating-templates).
## Customization Options
There are two main ways to customize templates on Vast.ai:
1. **Runtime customization with PROVISIONING\_SCRIPT** - Add a setup script that runs when the instance starts
* Works with any Docker image
* Simplest approach - no Docker build needed
* Perfect for installing packages, downloading models, configuring services
2. **Build custom Docker images** - Create your own Dockerfile with everything pre-installed
* Can start FROM Vast base images for built-in security features
* Or FROM any other base image
* Full control, faster instance startup
* Best for complex setups or frequently reused configurations
## PROVISIONING\_SCRIPT
Vast.ai templates support running a remote script on start to help configure the instance and download models and extensions that may not already be available in the Docker image.
This is the simplest way to customize a template - you start with one of our recommended templates (like `vastai/base-image` or `vastai/pytorch`) and add custom setup via a provisioning script.
### How to use
1. Go to the [Templates tab](https://cloud.vast.ai/templates/) in Vast.ai interface
2. Search for "base-image" or "Pytorch" depending on your needs:&#x20;
* `vastai/base-image` is a general purpose image
* `vastai/pytorch` is a base image for working with PyTorch-based applications on Vast
3. Click "Edit" on your chosen template
4. Add the PROVISIONING\_SCRIPT environment variable:&#x20;
* In the Environment Variables section, add a new variable named "PROVISIONING\_SCRIPT"
* The value should be a URL pointing to a shell script (from GitHub, Gist, etc.)
```curl Example URL theme={null}
https://raw.githubusercontent.com/karthik-vast-ai/vast-cli/distributed-inference-integration/provisioning_script.sh
```
5. Make sure to click "+" to add the environment variable
6. Click Create and Use

</Frame>
### Example PROVISIONING\_SCRIPT
```bash Bash theme={null}
#!/bin/bash
#
cd /workspace/
# Cause the script to exit on failure.
set -eo pipefail
# Activate the main virtual environment
. /venv/main/bin/activate
# Install your packages
pip install your-packages
# Download some useful files
wget -P "${WORKSPACE}/" https://example.org/my-application.tar.gz
tar xvf ${WORKSPACE}/my-application.tar.gz"
# Set up any additional services
echo "my-supervisor-config" > /etc/supervisor/conf.d/my-application.conf
echo "my-supervisor-wrapper" > /opt/supervisor-scripts/my-application.sh
chmod +x /opt/supervisor-scripts/my-application.sh
# Reconfigure the instance portal
rm -f /etc/portal.yaml
export PORTAL_CONFIG="localhost:1111:11111:/:Instance Portal|localhost:1234:11234:/:My Application"
# Reload Supervisor
supervisorctl reload
```
This script will run on first boot to set up your environment. All installations should go to /workspace/ for proper persistence.
### Configuring Application Access with PORTAL\_CONFIG
The base-image template includes PORTAL\_CONFIG for secure application access management. This environment variable controls how applications are exposed and accessed.
```bash PORTAL_CONFIG structure theme={null}
hostname:external_port:local_port:url_path:Application Name|hostname:external_port:local_port:url_path:Application Name
```
The structure of this variable is:
* Each application is separated by the `|` character
* Each application parameter is separated by the `:` character
* Each application must specify `hostname:external_port:local_port:url_path:Application Name`
Example:
```bash Bash theme={null}
"localhost:8002:18002:/hello:MyApp|localhost:1111:11111:/:Instance Portal|localhost:8080:18080:/:Jupyter|localhost:8080:8080:/terminals/1:Jupyter Terminal|localhost:8384:18384:/:Syncthing|localhost:6006:16006:/:Tensorboard"
```
The hostname in Docker instances will always be `localhost`
Where the internal port and local port are not equal then Caddy will be configured to listen on `0.0.0.0:external_port` acting as a reverse proxy for `hostname:local_port`
If the `external_port` and `local_port` are equal then Caddy will not act as a proxy but the Instance Portal UI will still create links. This is useful because it allows us to create links to Jupyter which is not controlled by Supervisor in Jupyter Launch mode.
`url_path` will be appended to the instance address and is generally set to `/` but can be used to create application deep links.
The `caddy_manager` script will write an equivalent config file at `/etc/portal.yaml` on boot if it does not already exist. This file can be edited in a running instance.
Important: When defining multiple links to a single application, only the first should have non equal ports - We cannot proxy one application multiple times.
Note: Instance Portal UI is **not** required and its own config declaration can be removed from `PORTAL_CONFIG`. This will not affect the authentication system.
## Building Custom Docker Images
If you want to create your own custom Docker image, you can optionally start FROM one of our [Vast.ai base images](https://hub.docker.com/r/vastai/base-image/tags) to get built-in security features and Instance Portal integration. See the [Introduction](/documentation/templates/introduction#vastai-base-images) for more details on why you might want to use Vast base images.
### Building FROM Vast Base Images
Start with a [Vast.ai base image](https://hub.docker.com/r/vastai/base-image/tags) or [Vast.ai Pytorch base image](https://hub.docker.com/r/vastai/pytorch/tags) in your Dockerfile:
```dockerfile Dockerfile theme={null}
#For example
FROM vastai/base-image:cuda-12.6.3-cudnn-devel-ubuntu22.04-py313
# or
FROM vastai/pytorch:2.6.0-cuda-12.6.3-py312
# Install your applications into /opt/workspace-internal/
# This ensures files can be properly synced between instances
WORKDIR /opt/workspace-internal/
# Activate virtual environment from base image
RUN . /venv/main/bin/activate
RUN your-installation-commands
```
After building your image:
1. [Build](https://docs.docker.com/build/) and [push your image](https://docs.docker.com/reference/cli/docker/image/push/) to a container registry
2. Create a new template and enter your custom image path in the Image Path:Tag field (see [Template Settings](/documentation/templates/template-settings#docker-repository-and-environment))
# Creating Templates
Source: https://docs.vast.ai/documentation/templates/creating-templates
## Introduction
Creating a template is simple - it's just telling Vast.ai how you want your instances to be configured. This guide will walk you through creating your first template step by step.
## Prerequisites
* A Vast.ai account
* [SSH client installed on your local machine and SSH public key added in the SSH Keys tab in the Keys section of your console](https://cloud.vast.ai/manage-keys/)&#x20;
* [(Optional) Install and use vast-cli](/cli/get-started)&#x20;
## Ways to Create Templates
You have three options:
### 1. Edit an Existing Template (Recommended for Beginners)
Start with one of our recommended templates and customize it to your needs. This is the easiest way to get started.
**Best for:** First-time users, quick customization of existing setups
### 2. Create from Scratch
Click "+ New" on the templates page for a blank template and configure everything yourself.
**Best for:** Users who know exactly what they need
### 3. Use an Existing Docker Image
Find a Docker image on DockerHub or another registry and create a template around it.
**Best for:** Users with a specific application in mind (e.g., nginx, postgres, a specific ML framework)
## Tutorial: Create Your First Template
Let's create a simple template together. We'll edit the NVIDIA CUDA template from the [Quick Start](/documentation/templates/quickstart) guide.
### Step 1: Open the Template Editor
1. Go to [cloud.vast.ai/templates](https://cloud.vast.ai/templates/)
2. Find the "NVIDIA CUDA" template (or any recommended template)
3. Click the pencil icon to edit

</Frame>
You'll see two tabs: `Config` and `ReadMe`. Stay on the Config tab.
### Step 2: Give Your Template a Name
In the **Identification** section:
* Change the **Template Name** to something descriptive (e.g., "My First Template")
* Add a **Template Description** if you'd like (optional)
### Step 3: Choose Your Docker Image
In the **Docker Repository And Environment** section, you'll see the **Image Path:Tag** field.
You can use:
* **Any public Docker image** (e.g., `nginx:latest`, `postgres:14`, `python:3.11`)
* **Vast.ai base images** (e.g., `vastai/base-image`, `vastai/pytorch`)
* **Your own custom images** from any registry
For this tutorial, keep the existing NVIDIA CUDA image or try `nginx:latest` for a simple web server.
<Note>
For a complete explanation of all Docker settings, see our [Template Settings](/documentation/templates/template-settings#docker-repository-and-environment) guide.
</Note>
### Step 4: Add Ports (Optional)
If your application needs external access, add ports in the **Ports** section.
For example, if you're running nginx, add port `80`.
### Step 5: Set Environment Variables (Optional)
If your Docker image requires environment variables, add them in the **Environment Variables** section.
<Warning>
Never put sensitive information (passwords, API keys) in template environment variables if you plan to make the template public. Use your [account settings](https://cloud.vast.ai/account/) instead.
</Warning>
### Step 6: Choose a Launch Mode
Select how you want to access your instance:
* **Jupyter + SSH** - Best for interactive development (default for most use cases)
* **SSH only** - If you don't need Jupyter
* **docker ENTRYPOINT** - If you want the container to run exactly as designed
For this tutorial, keep the default (Jupyter + SSH).
<Note>
For detailed information about launch modes, see our [Template Settings](/documentation/templates/template-settings#select-launch-mode) guide.
</Note>
### Step 7: Save Your Template
Scroll to the bottom and click one of the save buttons:
* **Create** - Saves the template to "My Templates" for later use
* **Create & Use** - Saves and immediately takes you to the offers page to rent an instance

# Creating Templates for GROBID
Source: https://docs.vast.ai/documentation/templates/examples/grobid
## Introduction
This guide demonstrates creating a template using an existing Docker image. See our [Creating Templates](/documentation/templates/creating-templates) guide for more details on template configuration. We will be using the image from [GROBID on dockerhub](https://hub.docker.com/r/grobid/grobid).
## Find The Image and Tag You Want to Use
### Step 1 - Find a Suitable Image
There are multiple GROBID images in dockerhub, but for this guide we will be using the official GROBID image.
<Frame caption="Grobid Overview">
![Grobid Overview](https://vast.ai/uploads/grobid_overview.png)
</Frame>
### Step 2 - Selecting the Version Tag
If you don't already have a version you intend to use, we recommend selecting the latest stable version.&#x20;
<Frame caption="Stable Tag">
![Stable Tag](https://vast.ai/uploads/stable_tag.png)
</Frame>
At the time of writing, the current stable version is 0.8.0, so that is the version we'll be using here.
## Configuring The Template
### Step 1 - Setting Your Chosen Image and Tag in Your Vast.ai Template
In the Docker Repository And Environment section, you will enter your image path and tag.
<Frame caption="Imageandtag">
![Imageandtag](https://vast.ai/uploads/templates/ImageAndTag.png)
</Frame>
### Step 2 - Map Ports and Specify Your Image and Tag Combination
The overview page for this image at dockerhub has a link to their guide to [using GROBID with containers](https://grobid.readthedocs.io/en/latest/Grobid-docker/#crf-and-deep-learning-image), which you can read to get their recommendations for containerizing GROBID.&#x20;
As we follow their guide to containerizing GROBID, we'll need to make sure the container's port 8070 is set to the host machine's port 8070. We will do that in the Vast.ai template. We use -p 8070:8070 as one of the docker run options.
<Frame caption="Run Cmd">
![Run Cmd](https://vast.ai/uploads/run_cmd.png)
</Frame>
**Note:** Vast only allows -e and -p docker run options to set environment variables and expose ports.
<Frame caption="Grobidport">
![Grobidport](https://vast.ai/uploads/templates/GrobidPort.png)
</Frame>
### Step 3 - Select the Launch Mode
Here we will select the SSH launch mode.
<Frame caption="Sshdirect">
![Sshdirect](https://vast.ai/uploads/templates/SSHDirect.png)
</Frame>
### Step 4 - Look for CMD or ENTRYPOINT command
<Frame caption="Found Tag">
![Found Tag](https://vast.ai/uploads/found_tag.png)
</Frame>
To find this for the template we are creating, we searched the [image's page in Dockerhub](https://hub.docker.com/r/grobid/grobid) and found the **CMD&#x20;**&#x63;ommand in the **Tags** tab under the link "0.8.0" highlighted in blue.
<Frame caption="Found Cmd">
![Found Cmd](https://vast.ai/uploads/found_cmd.png)
</Frame>
### Step 5 - Fill Out On-start Script section using the CMD command we just found
Next, we add the contents of the **CMD&#x20;**&#x63;ommand to the end of the bash commands section of the **On-start Script** fields.
Also, appended environment variables to /etc/environment file in our on-start section.

This makes environment variables available to all users and processes and ensures they are persistent even if our instance/docker container is rebooted. We suggest doing the same for your templates.
### Step 6 - Name and Save The Template
<Frame caption="Grobidexample">
![Grobidexample](https://vast.ai/uploads/templates/GrobidExample.png)
</Frame>
When you are finished setting up your template, If you haven't already done so, specify the template name and description.
Finally, click **Create & Use** to save the template and navigate to the GPU offers search page. You'll notice that your template is selected and ready to be used.
## Rent an Instance Using Your Template and Open GROBID Web App
Once you have selected an instance offer, You'll click on the **INSTANCES&#x20;**&#x6C;ink in the left menu and see your rented GPU instance that has your template applied.&#x20;

# Templates
Source: https://docs.vast.ai/documentation/templates/introduction
## What is a Template?
A template is how Vast helps you launch an instance, setting up your rented machine with whatever software and formatting you need. Templates are generally used for launching instances through the web interface, but they can also be used in the CLI or through the API. In this document, we will focus on the web interface, but we will link to other relevant documentation throughout.
In the simplest technical terms, you can consider a template to be a wrapper around `docker run`. The template contains all of the information you want to pass to our systems to configure the environment.
You can browse the template section of the web interface at [cloud.vast.ai/templates](https://cloud.vast.ai/templates/)
## Recommended Templates
We provide several recommended templates to help you get started. These are pre-configured environments that you can use as-is, or you can tweak them to your own requirements. &#x20;
<Note>
It's a great idea to look at how these templates have been configured to guide you in creating your own.
</Note>
### Vast.ai Base Images
Our recommended templates are built on Vast.ai base images like `vastai/base-image` and `vastai/pytorch`. You can find the source code on [`GitHub`](https://github.com/vast-ai/base-image/).
These are large Docker images that contain CUDA development libraries, node + npm, OpenCL and other useful libraries. Despite their large size you'll find they generally start quickly because they have been cached on many of the host machines.
**Why use Vast.ai base images?**
* **Faster cold boots** due to frequent caching on host machines
* **Built-in security features** through Caddy proxy
* **Automatic TLS encryption** for web services
* **Authentication token protection** for all services
* **Proper isolation** between external and internal services
* **Instance Portal** integration (explained below)
* **PROVISIONING\_SCRIPT** support for easy customization
### Instance Portal
When you click the Open button on an instance running one of our recommended templates, you'll see the Instance Portal:

The **Instance Portal** provides easy access links to services running in your instance. It places an authentication layer in front of these services to prevent access by anyone who does not have the correct authentication token. You can also create tunnels to your services without exposing ports.
Full documentation for the Instance Portal is available in our [Instance Portal guide](/documentation/instances/instance-portal).
### Virtual Machine Templates
In addition to standard Docker container templates, we also offer Virtual Machine (VM) templates. These launch a full virtual machine environment rather than a docker container.
**When to use VM templates:**
* Run applications that require namespace support
* Run more than one Docker container in an instance
* Load kernel modules or run profiling jobs
* Mount remote drives with rclone or similar
You can edit VM templates just like regular templates, but you should not change the docker image field. Only the images we distribute from `docker.io/vastai/kvm` will work.
### Customizing Recommended Templates
To learn how to customize our recommended templates with provisioning scripts or build your own custom Docker images, see our [Advanced Setup](/documentation/templates/advanced-setup) guide.
## Next Steps
Ready to start using templates? Here's what you can do:
* **Try it now** - Follow our [Quick Start](/documentation/templates/quickstart) guide to run your first template in minutes
* **Create your own** - See [Creating Templates](/documentation/templates/creating-templates) to build a custom template

## Sharing a Template
It's really easy to share your template with other users. We have two special links you can use and both include your referral code so you can earn if new users sign up - Find more about that [here](/documentation/reference/referral-program).
To share, click the three dots icon in the bottom right of the template card.
<Frame caption="Menu shows sharing options">

### Copy referral link
This will copy a link that contains your referral ID, creator ID and the template name. It will always point to the most recent template you created with this name - Really useful if you want people clicking the link to always get the most recent version.
### Copy template link&#x20;
This will copy a link containing your referral ID and the template hash ID. It points to this specific template at this point in time. &#x20;
Templates all have a unique hash after every save. This is useful as it allows you to find a previous version if you have tracked the hash ID, but for sharing you probably want the referral link above.
<Note>
Remember to add a comprehensive Readme to your template if you're going to share it. This will help users to get started easily.
</Note>
## Troubleshooting
* If your image is built for a different CPU architecture than your Vast machine, then it won't work. You can try to find a machine with the required CPU architecture using our GUI or [CLI](/cli/get-started).
* If your image requires a higher CUDA version, then look for a machine with a higher Max CUDA version. The Max CUDA version can be found on the instance card.&#x20;
* If your image is built to run jupyter, then try running it on a port different than 8080.
* If you are having issues using ssh launch mode, add your public key to \~/.authorized\_keys, install openssh, start openssh when the container starts, and forward the ssh server's port.

**Template Name**
This will be displayed in bold on the template card. Choose something that helps you identify the template amongst your other templates.
**Template Description**
This field helps describe the function and purpose of the template. Completely optional for your own purposes, but very helpful if you intend to make this template public or share it with others.
## Docker Repository And Environment
This is where you define the Docker image you want to run, along with any options we want to pass into the container.
<Frame caption="Docker section of the template editor">

**Image Path:Tag**
Here is where you can define the docker image to run. This field must be in the format `repository/image_name:tag`.
Many of our templates pull from DockerHub but you can use any container registry - Just remember to add the full path if you're using an alternative registry. Eg. `nvcr.io/nvidia/pytorch:25.04-py3`
You can use any Docker image:
* Public images from DockerHub (e.g., `nginx:latest`, `postgres:14`, `python:3.11`)
* Vast.ai base images (e.g., `vastai/base-image`, `vastai/pytorch`)
* Your own custom images from any registry
* Images from alternative registries (GitHub Container Registry, Google Container Registry, etc.)
**Version Tag**
For many registries we are able to pull the available list of tags so this field allows you to quickly select another version.
There is also a special `[Automatic]` tag you can use. With this selected, the machine you choose for your instance will pull the most recent docker image that is compatible with that machine's own CUDA version.&#x20;
This will only work if the image tag contains the CUDA version string. For example: `my-image-cuda-12.8` would be loaded on a machine supporting CUDA 12.8, but a machine with only CUDA 12.6 would pull `my-image-cuda-12.6`
**Docker Options**
This field is a textual representation of the ports and environment variables declared in the sections beneath it. You can edit it directly or you can use the page widgets.
<Note>
This field will only accept ports and environment variables. Other docker run options will be ignored.
</Note>
**Ports**
To access your instance via the external IP address, you will need to add some ports to the template. You can add both TCP and UDP ports.
When your instance is created, a port will be randomly assigned to the external interface which will map into the instance port you selected.
You can also use SSH to open a tunnel to access ports. Use a command like:
```text theme={null}
ssh -p [SSH_PORT] [USER]@[REMOTE_HOST] -L [LOCAL_PORT]:localhost:[REMOTE_PORT]
ssh -p 22 user@remote.example.com -L 8080:localhost:8080
```
The machine will forward traffic from the host machine's public port to the container port you specified.
**Environment Variables**
Here you can add any environment variables that your docker image requires. Do not save any sensitive information here if you are planning to make the template public.
Place any variables with sensitive values into the Environment Variables section of your [account settings page](https://cloud.vast.ai/account/). They will then be made available in any instance you create, regardless of the template used.
Special environment variables like `PROVISIONING_SCRIPT` and `PORTAL_CONFIG` can be used to customize Vast templates - see our [Advanced Setup](/documentation/templates/advanced-setup) guide for details.
You can find out more about port mapping and special environment variables in our [Docker Execution Environment](/documentation/instances/docker-execution-environment) guide.
## Select Launch Mode
Templates offer three launch modes you can select from. Our recommended templates will usually launch in Jupyter mode for easiest access, but you are free to choose whichever suits your needs.

**Jupyter-python notebook + SSH**
When you run the template in this mode, we will install Jupyter and SSH at runtime. Jupyter will be available on mapped port `8080` and SSH will be available on mapped port `22`.
**Interactive shell server, SSH**
As above, but SSH only with no Jupyter installation.
<Warning>
In both Jupyter and SSH mode, the docker entrypoint for your image will not be run. It will be replaced with our instance setup script so you should use the on start section (documented below) to start any services.
</Warning>
**docker ENTRYPOINT**
In this mode, your Docker image will run precisely as it is. We will not include any additional software or access methods. If your Docker image does not offer SSH or another appropriate interface, please select one of the alternative modes if you need to interact with the running instance.
An additional field will be shown when using this launch mode to allow passing arguments to the image entrypoint.

## On-start Script
Here you can enter a short Bash script which will be run during instance startup. It is only available when using the Jupyter or SSH launch modes, and is most useful for starting any services that your docker image would have launched if the entrypoint had been executed.

</Frame>
**Additional On-start Script Examples**
You can execute custom startup scripts:
```text theme={null}
chmod +x /usr/local/bin/start.sh
bash /usr/local/bin/start.sh
```
You can also overwrite existing files built into the image. Make sure you can switch to a user that has write permissions to that particular file.
For example, you can remove all instances of '-sslOnly' in a particular file using sed:
```text theme={null}
sed -i 's/-sslOnly//g' /dockerstartup/vnc_startup.sh
```
You can also make directories:
```text theme={null}
sudo -i -u kasm-user mkdir -p /home/kasm-user/Desktop
```
Make sure to append environment variables to /etc/environment file in your on-start section because this makes environment variables available to all users and processes and ensures they are persisted even if your instance/docker container is rebooted:
```text theme={null}
env >> /etc/environment
```
Also make sure to find the image's ENTRYPOINT or CMD command and call that command at the end of the on-start section. We overwrite that command to set up jupyter/ssh server, etc. under the hood.

## Docker Repository Authentication
If you are using a private Docker image then you will need to add authentication credentials so the machine running the instance can download it.

**Docker Registry Server Names**
You don't have to specify docker.io as the server name if your repository is Docker Hub. Docker automatically uses docker.io to pull the image if no other registry is specified.
You do have to specify your server name if your repository is something else. For example:
* GitHub Container Registry (GHCR) - Server Name: `ghcr.io`
* Google Container Registry (GCR) - Server Name: `gcr.io`
## Disk Space
By setting the disk space in the template, you can ensure that new instances created from the template will use this amount as a minimum.&#x20;

# Google Colab
Source: https://docs.vast.ai/google-colab
Google Colab is a flavor of Jupyter notebook. The service is not meant to be run on cloud based GPUs. This guide provides a "hack" that uses SSH port forwarding so that Colab detects the Vast GPU instance as a local GPU and connects to the remote instance.
<Note>
For simple notebooks, we recommend downloading the notebook from Goolge Colab as a .ipynb file, running a Vast Jupyter instance with the recommended [Pytorch template](https://cloud.vast.ai/?ref_id=43484\&template_id=f5540ef1a1398b8499546edb53dae704) and then uploading the notebook into Jupyter directly. Jupyter by itself is much more reliable than Google Colab, doesn't require setting up SSH keys (you can open a terminal inside the browser), and has none of the limitations.
</Note>
## Run any Google Colab notebook on Vast
Colab supports a 'local runtime' option to allow people to run colab connecting to their local machine, using their own GPUs. This feature is **intentionally restricted** to allow only a localhost connection. Getting around that restriction requires using ssh forwarding to make a remote Jupyter instance appear local.
## Known issues and limitations
Colab is connecting to a remote Jupyter instance using SSH forwarding. If you close your browser, you might not be able to re-open the session. To fix that you will need to stop and then restart Jupyter through the SSH connection, get a new token, and then use that to reconnect to the local runtime in Colab.
Another small limitation is that there is no way (unless you get Colabs Pro) to open a terminal from within Colab. A simple Jupyter Vast instance doesn't have that limitation and you can always open a terminal right in the browser.
## Step 1 - Create a Pytorch SSH instance
Use this [Colab template](https://cloud.vast.ai/?ref_id=43484\&template_id=8d383ad48fff4012d42806e4781020ef) that uses the common Pytorch image with a direct SSH launch mode.
After clicking on that link, your instance configuration will be set. Setup an account, purchase credits and then select an appropriate GPU by clicking the "rent" button.
## Step 2 - SSH into the instance
Our default SSH command for Linux/macOS already forwards port 8080. The default SSH command can be found by clicking on the Connect button from a rented instance. Run that command. You will then have an active SSH connection to the GPU instance.
## Step 2.5 - Windows Only
On Windows, Colab is more complicated. The reason is that Windows has no simple SSH client built-in, unlike Linux/macOS. One solution is to install [WSL](https://learn.microsoft.com/en-us/windows/wsl/about) and then use the SSH command provided on the Vast instance. Or you can follow our [Windows SSH Guide](/documentation/instances/windows-ssh-guide) and use Putty tools to generate your SSH keys and SSH into the instance.
There is one additional Windows step if you use Putty tools. After making sure you can SSH into the instance, close the SSH connection and then modify your Putty configuration to forward port 8080 to local host.
Go to Connection->SSH->Tunnels. In the "source port" add 8080. Then in "destination" add:
```text Text theme={null}
localhost:8080
```
Then click back to "Session" and save your configuration. You can then click the Open button to start the Windows SSH session with port 8080 forwarded to localhost.
## Step 3 - Run Jupyter
Run Jupyter with options like these (adjust the port 8080 to match whatever port you forwarded over SSH):
```text Text theme={null}
jupyter notebook --NotebookApp.allow_origin='*' --port=8080 --NotebookApp.port_retries=0 --allow-root --NotebookApp.allow_remote_access=True
```
That will output a couple of http addresses. You want to use the localhost address with the access token. Make sure to copy the entire string so you can paste it into your Colab session.
## Step 4 - Connect to local runtime
Open Google Colab and hit the Connect button and select the option to "connect to local runtime". Paste in the localhost URL from your SSH session into the box and hit connect. Colab will then initialize and make the connection.
## If SSH connection drops
If your SSH connection disconnects due to a network error or other reason, the Google colab instance will throw an error and give you the option to reconnect.
The first thing to do is to reconnect via SSH to the Vast instance. Once that is established, you can try to "reconnect" to the Google colab instance, but that typically does not work.
The only way to re-establish a connection is to stop the Jupyter running on the Vast instance and then restart it. Then you can take the new URL + token and reconnect on Google Colab.
This can cause other problems to the running notebook. You may or may not need to then re-run all the cells of your notebook.
All your data will still be on the Vast instance and available to be copied, even if Colab cannot connect to your instance.
# Huggingface TGI with LLama3
Source: https://docs.vast.ai/huggingface-tgi-with-llama3
This is a guide on how to setup and expose an API for Llama3 Text Generation.
>
## 1) Choose The Huggingface LLama3 TGI API Template From the Recommended Section
Login to your Vast account on the [console](https://cloud.vast.ai)
Select the [HuggingFace Llama3 TGI API](https://cloud.vast.ai/?template_id=906891f677fb36f21662a92e6092b5fc) template by clicking the link provider
For this template we will be using the meta-llama/Meta-Llama-3-8B-Instruct model, and the TGI 2.0.4 from Huggingface
Templates encapsulate all the information required to run an application with the autoscaler, including machine parameters, docker image, and environment variables.
For this template, the only requirement is that you have your own Huggingface access token. You will also need to apply to have access to Llama3 on huggingface in order to access this gated repository.
The template comes with some filters that are minimum requirements for TGI to run effectively. This includes but is not limited to a disk space requirement of 100GB, and a gpu ram requirement of at least 16GB.
After selecting the template your screen should look like this:

Once you have selected the template, you will need to then add in your huggingface token and click the 'Select & Save' button.
You can add your huggingface token with the rest of the docker run options.
<Frame caption="Edithf">
![Edithf](https://vast.ai/uploads/HuggingFace/EditHf.png)
</Frame>
This is the only modification you will need to make on this template.
You can then press 'Select & Save' to get ready to launch your instance.
## 3) Rent a GPU
Once you have selected the template, you can then choose to rent a GPU of your choice from either the search page or the CLI/API.
For someone just getting started I recommend either an Nvidia RTX 4090, or an A5000.
<Frame caption="Rent">
![Rent](https://vast.ai/uploads/HuggingFace/Rent.png)
</Frame>
## 4) Monitor Your Instance
Once you rent a GPU your instance will being spinning up on the Instances page.
You know the API will be ready when your instance looks like this:
<Frame caption="Llama3Tgiinstances">
![Llama3Tgiinstances](https://vast.ai/uploads/llama3tgiinstances.png)
</Frame>
Once your instance is ready you will need to find where your API is exposed. Go to the IP & Config by pressing the blue button on the top of the instance card. You can see the networking configuration here.
<Frame caption="Llama3Ip">
![Llama3Ip](https://vast.ai/uploads/llama3ip.png)
</Frame>
After opening the IP & Port Config you should see a forwarded port from 5001, this is where your API resides. To hit TGI you can use the '/generate' endpoint on that port.
Here is an example:
<Frame caption="Llama3Tgipostman">
![Llama3Tgipostman](https://vast.ai/uploads/llama3tgipostman.png)
</Frame>
## 5) Congratulations!
You now have a running instance with an API that is using TGI loaded up with Llama3 8B!

* Username: `vastai`
* Password: Check `OPEN_BUTTON_TOKEN` value
* To find token: `echo $OPEN_BUTTON_TOKEN` in terminal
* **API Access**:
```bash theme={null}
curl -X POST https://[INSTANCE_IP]:[MAPPED_PORT]/endpoint \
-H 'Authorization: Bearer <OPEN_BUTTON_TOKEN>' \
...
```
* **Security Setup**:
* HTTPS and token authentication enabled by default
* Install TLS certificate to avoid browser warnings
* Configure via `WEB_ENABLE_HTTPS` and `WEB_ENABLE_AUTH` variables
* **Jupyter Access for Uploading/Downloading**:
* You can access jupyter clicking on the jupyter button on the instance card to easily upload and download files
## Working with Models
### Managing Models
### Default Setup
The template includes a default provisioning script that downloads:
* Base Stable Diffusion XL models
* Popular extensions
* Common configurations
### Custom Provisioning
Create your own setup by:
1. Copy the default provisioning script by editing the SD Web UI Forge template and grabbing the value of `PROVISIONING_SCRIPT` environment variable and downloading it
2. Modify it to download your preferred:
* Models
* Extensions
* Configurations
3. Upload to Gist/Pastebin
4. Edit the template and set `PROVISIONING_SCRIPT` environment variable to the raw URL
Example for adding more models:
```bash Bash theme={null}
# Navigate to models directory
cd /workspace/stable-diffusion-webui/models/Stable-diffusion
# Download new models (example)
wget https://civitai.com/api/download/models/[MODEL_ID]
```
### Model Organization
Keep your models organized:
```text Text theme={null}
/workspace/stable-diffusion-webui/models/
├── Stable-diffusion/ # Main models
├── Lora/ # LoRA models
├── VAE/ # VAE files
└── embeddings/ # Textual inversions
```
You can access jupyter clicking on the jupyter button on the instance card to easily upload and download files.

# Infinity Embeddings
Source: https://docs.vast.ai/infinity-embeddings
# Serving Infinity Embeddings with Vast.ai
## Background:
Infinity Embeddings is a helpful serving framework to serve embedding models. It is particularly great at enabling embedding, re-ranking, and classification out of the box. It supports multiple different runtime frameworks to deploy on different types of GPU’s while still achieving great speed. Infinity Embeddings also supports dynamic batching, which allows it to process requests faster under significant load.
One of its best features is that you can deploy multiple models on the same GPU at the same time, which is particularly helpful as often times embedding models are much smaller than GPU RAM. We also love that it complies with the OpenAI embeddings spec, which enables developers to quickly integrate this into their application for rag, clustering, classification and re-ranking tasks.
This guide will show you how to setup Infinity Embeddings to serve an LLM on Vast. We reference a note book that you can use [here](https://nbviewer.org/urls/bitbucket.org/%21api/2.0/snippets/jsbcannell/nE66og/f86a1c070ddc362abc6572eb300926a0b7190ad3/files/serve_infinity_on_vast.ipynb)
```bash Bash theme={null}
pip install --upgrade vastai
```
Once you create your account, you can go [here](https://cloud.vast.ai/cli/) to set your API Key.
```bash Bash theme={null}
vastai set api-key <Your-API-Key-Here>
```
For serving an LLM, we're looking for a machine that has a static IP address, ports available to host on, plus a single modern GPU with decent RAM since these embedding models will be small. We will query the vast API to get a list of these types of machines.
```bash Bash theme={null}
vastai search offers 'compute_cap > 800 gpu_ram > 20 num_gpus = 1 static_ip=true direct_port_count > 1'
```
## Deploying the Image:
### Hosting a Single Embedding Model:
For now, we'll host just one embedding model.
The easiest way to deploy a single model on this instance is to use the command line. Copy and paste a specific instance id you choose from the list above into `instance-id` below.
We particularly need `v2` so that we use the correct version of the api, `--port 8000` so it serves on the correct model, and `--model-id michaelfeil/bge-small-en-v1.5` to serve the correct model.
```bash Bash theme={null}
vastai create instance <instance-id> --image michaelf34/infinity:latest --env '-p 8000:8000' --disk 40 --args v2 --model-id michaelfeil/bge-small-en-v1.5 --port 8000
```
## Connecting and Testing:
Once your instance is done setting up, you should see something like this:
<Frame caption="IP_address_view">
![IP\_address\_view](https://vast.ai/uploads/ip_address_view_infinity.png)
</Frame>
Click on the highlighted button to see the IP address and correct port for our requests. To connect to your instance, we'll first need to get the IP address and port number.
<Frame caption="Instance_view">
![Instance\_view](https://vast.ai/uploads/instance_view_infinity.png)
</Frame>
Now we'll call this with the Open AI SDK:
```bash Bash theme={null}
pip install openai
```
We will copy over the IP address and the port into the cell below.
```python icon="python" Python theme={null}
from openai import OpenAI
# Modify OpenAI's API key and API base to use vLLM's's API server.
openai_api_key = "EMPTY"
openai_api_base = "http://<Instance-IP-Address>:<Port>/v1"
client = OpenAI(
api_key=openai_api_key,
base_url=openai_api_base,
)
model = "michaelfeil/bge-small-en-v1.5"
embeddings = client.embeddings.create(model=model, input="What is Deep Learning?").data[0].embedding
print("Embeddings:")
print(embeddings)
```
In this, we can see that the embeddings from our model. Feel free to delete this instance as we'll redeploy a different configuration now.
### Advanced Usage: Rerankers, Classifiers, and Multiple Models at the same time
The following steps will show you how to use Rerankers, Classifiers, and deploy them at the same time. First, we'll deploy two models on the same GPU and container, the first is a reranker and the second is a classifier. Note that all we've done is change the value for `--model-id`, and added a new `--model-id` with its own value. These represent the two different models that we're running.
```bash Bash theme={null}
vastai create instance <instance-id> --image michaelf34/infinity:latest --env '-p 8000:8000' --disk 40 --args v2 --model-id mixedbread-ai/mxbai-rerank-xsmall-v1 --model-id SamLowe/roberta-base-go_emotions --port 8000
```
Now, we'll call these models with the requests library and follow `Infinity`'s API spec. Add your new IP address and Port here:
```python icon="python" Python theme={null}
import requests
base_url = "http://<Instance-IP-Address>:<Port>"
```
```python icon="python" Python theme={null}
rerank_url = base_url + "/rerank"
model1 = "mixedbread-ai/mxbai-rerank-xsmall-v1"
input_json = {"query": "Where is Munich?","documents": ["Munich is in Germany.", "The sky is blue."],"return_documents": "false","model": "mixedbread-ai/mxbai-rerank-xsmall-v1"}
headers = {
"accept": "application/json",
"Content-Type": "application/json"
}
payload = {
"query": input_json["query"],
"documents": input_json["documents"],
"return_documents": input_json["return_documents"],
"model": model1
}
response = requests.post(rerank_url, json=payload, headers=headers)
if response.status_code == 200:
resp_json = response.json()
print(resp_json)
else:
print(response.status_code)
print(response.text)
```
We can see from the output of the cell that it gives us a list of jsons for each score, in order of highest relevance. Therefore in this case, the first entry in the list had a relevancy of .74, meaning that it "won" the ranking of samples for this query.
And we'll now query the classification model:
```python icon="python" Python theme={null}
classify_url = base_url + "/classify"
model2 = "SamLowe/roberta-base-go_emotions"
headers = {
"accept": "application/json",
"Content-Type": "application/json"
}
payload = {
"input": ["I am feeling really happy today"],
"model": model2
}
response = requests.post(classify_url, json=payload, headers=headers)
if response.status_code == 200:
resp_json = response.json()
print(resp_json)
else:
print(response.status_code)
print(response.text)
```
We can see from this that the most likely emotion from this model's choices was "joy".
So there you have it, now you can see how with Vast and Infinity, you can serve embedding, reranking, and classifier models all from just one GPU on the most affordable compute on the market.
# Langflow + Ollama
Source: https://docs.vast.ai/langflow-ollama
Langflow is a node-based agent builder you can use from your web browser. While it integrates with many frontier language models it also has a fantastic Ollama integration which makes it really easy to use with open weight models as well as custom fine-tunes.
We have two templates you can choose for this guide. The **Langflow template** provides both Ollama and Langflow installed within the instance. You can also use the [**Ollama standalone template**](https://cloud.vast.ai/?ref_id=62897\&creator_id=62897\&name=Ollama) to integrate with a local langflow installation via [ssh local port forwarding](/documentation/instances/sshscp#Yj5Wh). The choice is yours. For this guide we will use the Langflow bundled template.
Before moving on with the guide,**&#x20;Setup your Vast account and add credit**. Review the [quickstart guide](/documentation/get-started/quickstart) to get familar with the service if you do not have an account with credits loaded.
## Initial Setup
Let's get started with the configuration - There is not much you need to change here but it's a good idea to create a customized version of the template so Ollama automatically downloads your preferred model.
### Find the Template
You can find the Langflow template in our [recommended templates](https://cloud.vast.ai/templates/) page. Before loading it up, click the pencil icon to open up the template editor

### Custom configuration
In the template editor you'll find two really useful configuration variables.
* `OLLAMA_MODEL` is the most important variable. Here you can choose which model should be downloaded when the instance starts.
* `LANGFLOW_ARGS`allows you to pass alternative startup arguments to the langflow application. The defaults should be fine for this demo, but you are free to change these as you need.

When you have finished entering your settings click the '**Create & Use**' button to save your copy of the template.
You'll be taken to the search interface where you can choose an appropriate GPU instance to run your model. You can access your custom template in future from the 'My Templates' section of the templates page.
## Starting the Instance
It's now time to use your template to start a GPU instance.
### Choose a GPU
The most important consideration when picking an instance to run laguage models is the VRAM. For best performance, your model weights must fit into the GPU VRAM with room left over for the context window.&#x20;
You do not have to use a single GPU when running LLMs - Sometimes a multi-GPU setup can be as effective of better than a single high VRAM instance.
### Rent an Instance
When you have found a suitable instance it's time to click the '**Rent**' button. This will start the loading phase.
<Note>
If you are not sure which instance to choose - Try one. There is no minimum rental period and if it is not suitable you are able to destroy that instance and start another, paying only for the time the instance was in the 'running' state
</Note>
## Accessing the Instance
After a short time, your instance will be ready to access. Simply click the 'Open' button to get started.

## Creating and Configuring VMs
### Search for Ubuntu VM Template
Go to [Templates tab](https://cloud.vast.ai/templates/) and search for recommended Ubuntu 22.04 VM template.
### Edit Template as Needed
When you find the Ubuntu 22.04 VM template, you can edit the template.&#x20;
### **Environment Variables**
You can set environment variables by editing the VM template and adding a specific environment variable name and value in the Environment Variables section or adding a line like this to "Docker options" field:
```docker Docker theme={null}
-e JUPYTER_DIR=/ -e TEST=OK
```
Variables are written to `/etc/environment.`To use these environment variables in a script once you're inside your machine, run this command:
```linux Linux theme={null}
source /etc/environment
```
### Expose Ports Publicly
You can expose ports publicly by editing the VM template and adding specific ports in Ports section or adding a line similar to this in "Docker options" field:
```docker Docker theme={null}
-p 8081:8081 -p 8082:8082/udp -p 70000:70000
```
### Specify On-Start Script Configuration&#x20;
The On-start script field allows specifying a script to run on instance start. Unlike in docker-based instances, the interpreter must be specified by a shebang. Here's an example for bash:
```linux Linux theme={null}
#!/bin/bash
```
## Rent a Machine
Rent a machine of your choice from the [Search tab](https://cloud.vast.ai/create/).
You can see the instance being created in the Instances tab. It can take some time to load.
## Connect to Your VM
Once the blue button the instance card says **>\_CONNECT**, you can click the button and copy the ssh command to execute in your terminal in your Mac or Linux-based computer. You can also use [Powershell or Windows Putty tools](/documentation/instances/sshscp) if you have a Windows computer.
## VM Management
### Cloud Copy Utility
* Different from Docker-based instances
* Use cli command: `vastai vm copy $SRC_VM_ID $DEST_VM_ID`
* Limitations:
* Only supports full VM migration
* Copying between VMs only (no external storage support)
* No individual folder copy support
### Best Practices
* **Resource Management**
* Monitor disk usage due to higher overhead
* Plan for longer boot times in your workflows
* **Security**
* Keep SSH keys secure
* Configure firewall rules appropriately
* Regular security updates
* **Performance Optimization**
* Use appropriate VM sizes for your workload
* Monitor resource utilization
* Clean up unused resources
## Troubleshooting
### Common Issues
* **VM Won't Start**
* Check if SSH key is added in Account
* Verify that rented machine supports VMs
* **Environment Variables Not Working**
* Ensure variables are properly set in Docker options
* Check if `/etc/environment` is being sourced
* Verify script permissions
* **Connectivity Issues**
* Verify SSH key permissions
* Check network configuration
* Confirm port forwarding setup
* Try a different host machine

## Conclusion
Virtual Machines on Vast.ai provide powerful capabilities for specific use cases, particularly those requiring full system control or containerization support. While they have some limitations compared to Docker instances, their flexibility and isolation make them ideal for many advanced computing scenarios.
# Mining on Bittensor
Source: https://docs.vast.ai/mining-on-bittensor
# Vast internal guide to test subnets inside the Opentensor image
This tutorial shows how to use the Bittensor testnet to create a subnet and run your incentive mechanism on it.
## 1. Install Bittensor subnet template
`cd` into your project directory and clone the bittensor-subnet-template repo:
```bash Bash theme={null}
git clone https://github.com/opentensor/bittensor-subnet-template.git
```
Next, `cd` into bittensor-subnet-template repo directory:
```bash Bash theme={null}
cd bittensor-subnet-template # Enter the
```
Install the bittensor-subnet-template package:
```bash Bash theme={null}
python -m pip install -e .
```
## 2. Create wallets
Create wallets for subnet owner, subnet validator and for subnet miner.
Follow all of these steps:
```bash Bash theme={null}
btcli wallet new_coldkey --wallet.name owner
```
Create a coldkey and hotkey for your miner wallet:
```bash Bash theme={null}
btcli wallet new_coldkey --wallet.name miner
```
and
```bash Bash theme={null}
btcli wallet new_hotkey --wallet.name miner --wallet.hotkey default
```
Create a coldkey and hotkey for your validator wallet:
```bash Bash theme={null}
btcli wallet new_coldkey --wallet.name validator
```
and
```bash Bash theme={null}
btcli wallet new_hotkey --wallet.name validator --wallet.hotkey default
```
## 3. Get the price of subnet creation
Creating subnets on the testnet is competitive. The cost is determined by the rate at which new subnets are being registered onto the chain.
```bash Bash theme={null}
btcli subnet lock_cost --subtensor.network test
```
The above command will show:
```bash Bash theme={null}
>> Subnet lock cost: τ100.000000000
```
## 4 Go to the Bittensor discord channel and ask them for test Taos
Here is the [link](https://discord.com/channels/799672011265015819/830068283314929684) to the discord channel for Bittensor.
## 4.5 Transfer test Taos to your miner wallet
Use the following command to list all your wallets:
```text Text theme={null}
btcli w list
```
You will get an output like this:
```text Text theme={null}
Wallets
├──
│ owner (5FyRdpzddeN7KGLhn6S6ia1up7dzbtXiZ5trc2hmm9AN9Pj4)
├──
│ miner (5GCahkVacWRHzVgRBfSmnt11gHnWWZhkapquzPEwR7je1a8w)
│ └── default (5CUgZBi3GQpJDhe1EhdPJfzBb6pyWvnkuSWJ6SBhEpSby1XP)
└──
validator (5FZSLAZsiFaZzhcL2oxMesSrQQHmWHSGpPfNjMUmiruBpYGB)
└── default (5EqaFbjHDUQCHRbG5592QvCbpNkvAxsLCLKRNoLaVLN76g55)
```
Then transfer 0.001 Taos to your miner and validator wallet.
### Transfer to miner wallet
```text Text theme={null}
btcli wallet transfer --dest 5GCahkVacWRHzVgRBfSmnt11gHnWWZhkapquzPEwR7je1a8w --wallet.name owner --amount 0.001 --subtensor.network test
```
Make sure the --dest key is the same as your wallet key that you get from the btcli w list command.
### Transfer to validator wallet
Repeat this step for the validator wallet as well.
```text Text theme={null}
btcli wallet transfer --dest 5FZSLAZsiFaZzhcL2oxMesSrQQHmWHSGpPfNjMUmiruBpYGB --wallet.name owner --amount 0.001 --subtensor.network test
```
## 6. Register keys
This step registers your subnet validator and subnet miner keys to the subnet, giving them the **first two slots** on the subnet.
Register your miner key to the subnet:
```bash Bash theme={null}
btcli subnet register --netuid 15 --subtensor.network test --wallet.name miner --wallet.hotkey default
```
Follow the below prompts:
```bash Bash theme={null}
>> Enter netuid [1] (1): # Enter netuid 1 to specify the subnet you just created.
>> Continue Registration?
hotkey: ...
coldkey: ...
network: finney [y/n]: # Select yes (y)
>> ✅ Registered
```
Next, register your validator key to the subnet:
```bash Bash theme={null}
btcli subnet recycle_register --netuid 15 --subtensor.network test --wallet.name validator --wallet.hotkey default
```
Follow the prompts:
```bash Bash theme={null}
>> Enter netuid [1] (1): # Enter netuid 1 to specify the subnet you just created.
>> Continue Registration?
hotkey: ...
coldkey: ...
network: finney [y/n]: # Select yes (y)
>> ✅ Registered
```
## 7. Check that your keys have been registered
This step returns information about your registered keys.
Check that your miner has been registered:
```bash Bash theme={null}
btcli wallet overview --wallet.name miner --subtensor.network test
```
The above command will display the below:
```bash Bash theme={null}
Subnet: 1
COLDKEY HOTKEY UID ACTIVE STAKE(τ) RANK TRUST CONSENSUS INCENTIVE DIVIDENDS EMISSION(ρ) VTRUST VPERMIT UPDATED AXON HOTKEY_SS58
miner default 1 True 0.00000 0.00000 0.00000 0.00000 0.00000 0.00000 0 0.00000 14 none 5GTFrsEQfvTsh3WjiEVFeKzFTc2xcf…

Wallet balance: τ0.0
```
## 8. Run subnet miner and subnet validator
Run the subnet miner:
```bash Bash theme={null}
python neurons/miner.py --netuid 15 --subtensor.network test --wallet.name miner --wallet.hotkey default --logging.debug
```
You will see the below terminal output:
```bash Bash theme={null}

# Multi-Node training using Torch + NCCL
Source: https://docs.vast.ai/multi-node-training-using-torch-nccl
<Note>
Need RoCE or Infiniband? Submit a [cluster request](https://vast.ai/products/clusters). Availability currently limited to A100/H100/H200 machines.
</Note>
<Note>
Note: Private networking currently only available on Docker-based templates; not available for VM-based templates. &#x20;
</Note>
NCCL expects all nodes to be on the same network. By default, Vast instances on different physical machines are on separate bridge networks isolated from the host's LAN and must go through a NAT to reach the outside internet.&#x20;
Vast now supports creating *overlay* networks for instances, allowing client instances on different machines on the same physical LAN to share a private, virtual LAN separate from both the host network and the networks of other clients' instances.&#x20;
Overlay networks can be created for instances located in the same *physical cluster* --- these are groups of machines that support fast local networking to each other.&#x20;
This allows direct communication between the instances on all ports, which is expected by NCCL.&#x20;
## Creating a Virtual Cluster
* Make sure to update to/install the newest version of the CLI first: go to our [CLI docs](https://cloud.vast.ai/cli/) and copy+run the command starting with `wget`.
* View physical clusters with instances matching your requirements by running `./vast search offers --raw cluster_id!=None [YOUR_INSTANCE_SEARCH_FILTERS] | grep cluster_id`
* This will print out cluster\_ids for clusters with offers available for instances matching your search parameters.&#x20;
* For a detailed view of the available offers within a specific cluster, run `./vast search offers cluster_id=CLUSTER_ID [YOUR_INSTANCE_SEARCH_FILTERS]`&#x20;
* Once you've chosen a physical cluster, create your overlay network inside the cluster---
* `./vast create overlay CLUSTER_ID NAME_FOR_NETWORK_TO_CREATE`
* Search for instance offers in the physical cluster you created your overlay network in---
* `./vast search offers cluster_id=CLUSTER_ID [YOUR_INSTANCE_SEARCH_FILTERS]`
* Create instances attached to your overlay by appending `--env "-n YOUR_NETWORK_NAME"` to your `./vast create instance` command.&#x20;
## TCP Initialization for NCCL + PyTorch
Depending on your setup, you will have one or more worker processes running on each node. NCCL expects each worker process to be assigned a unique rank that's an integer from 0-(NUM\_WORKERS - 1).&#x20;
NCCL expects to be able to perform a TCP rendezvous during initialization at the local IP address of the node running the rank 0 worker process.&#x20;
### Finding the IPv4 address for TCP rendezvous
* On the node that will run the rank 0 worker, run `ip a` (`apt install iproute2` if not already installed).&#x20;
* You should have three network interfaces: `lo`, `eth0`, and `eth1`.&#x20;
* Unless you added/removed networks after instant creation, `eth0` should be the interface to the overlay network between your instances. ( `lo` is the loopback interface; `eth1` is a bridge to the host machine's gateway to the external internet).&#x20;
* Under the `eth0` entry, there should be the line that starts with `inet IPv4ADDRESS/MASK`, this `IPv4ADDRESS` will be the address you will want to use for TCP initialization.&#x20;
### Running the training script
* In your training script, you'll want to initialize your process group at the beginning every worker process with the parameters `backend='nccl'` and `init_method = 'tcp://IPv4ADDRESS:PORT'` where `IPv4ADDRESS` is the IPv4 address of your `eth0` device as found using the instructions above, and port is a free port number chosen between 1000 and 65535 (all ports are exposed between instances on the same overlay network).&#x20;
* You may need to set the `NCCL_SOCKET_IFNAME=eth0` environment variable for the script, as NCCL is sometimes unable to detect that the `eth1` device on the different nodes are not directly connected to each other.&#x20;
* Other debugging notes:
* NCCL may not initialize all channels until the first communication function is called.&#x20;
* Setting the `NCCL_DEBUG=INFO` environment variable may be useful for getting additional debug info.
* PyTorch sometimes does not block on communication methods finishing until the output tensors area actually used. &#x20;
### Example
Here we will use a python script called `nccl_speedtest.py` using the following contents:&#x20;
```python icon="python" Python theme={null}
import torch as t
import torch.distributed as dist
import sys
import time
import string
# tests nccl bandwidth between two nodes.
# Run this script on both nodes, setting one as RANK 0 and the other as RANK 1
# Invoke: python3 nccl_speedtest.py NODE_0_IP:PORT SIZE[K|M|G] RANK(0|1)
if __name__ == "__main__":
handshake_ip = sys.argv[1]
size_s = sys.argv[2]
split_idx = size_s.find(string.ascii_letters)
sizes = { "K" : 1024, "M" : 1024**2, "G" : 1024 ** 3, "":1}
size = int(size_s[0:split_idx]) * sizes[size_s[split_idx:]]
rank = int(sys.argv[3])
if len(sys.argv) >= 5:
device = int(sys.argv[4])
else:
device = 0
print("Initializing tensors...")
# number of fp32 to allocate is bytes >> 2
v1 = t.rand(size>>3, device=f'cuda:{device}') # for bidirectional test
warmup1 = t.rand(size>>13, device=f'cuda:{device}')
if rank:
warmup = t.rand(size>>12, device=f'cuda:{device}')
v = t.rand(size>>2, device=f'cuda:{device}')
else:
warmup = t.zeros(size>>12,device=f'cuda:{device}')
v = t.zeros(size>>2, device=f'cuda:{device}')
print("Executing NCCL TCP handshake...")
dist.init_process_group(init_method = f"tcp://{handshake_ip}", rank = rank, world_size=2)
print("NCCL TCP handshake done, warming up connection...")
if rank:
dist.send(warmup, 0)
else:
dist.recv(warmup,1)
ignore = t.sum(warmup).to('cpu') # force sync
print("Warmup done; starting uni-directional speedtest...")
start = time.time()
if rank:
dist.send(v, 0)
else:
dist.recv(v,1)
# Torch returns from dist.send/dist.recv as soon as the communication channels initialize; it does not block on the full tensor being received.
# t.sum(v) will block on communication operations on v completing though, so we don't check end time until that is done.
checksum = t.sum(v).to('cpu')
end = time.time()
print(f"Checksum: {checksum}")
print(f"elapsed: {end-start}")
print(f"unidirectional bandwidth: {size / (end-start) / sizes['M']} MiB/s")
print("Warming up bidirection speedtest...")
dist.all_gather_into_tensor(warmup,warmup1)
print("Warmup done, starting bidirectional speedtest...")
start = time.time()
dist.all_gather_into_tensor(v, v1)
checksum = t.sum(v).to('cpu')
end = time.time()
print(f"Checksum: {checksum}")
print(f"elapsed: {end-start}")
print(f"bidirectional bandwidth: {size / (end-start) / sizes['M']} MiB/s")
print("Done, cleaning up!")
dist.destroy_process_group()
```
We will have rented two instances on the same overlay network already.
On the first instance:&#x20;
Run `apt update; apt install iproute2` then run `ip a`:&#x20;
We should get output that looks like this ----
```text Text theme={null}
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host noprefixroute
valid_lft forever preferred_lft forever
2: eth0@if23: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/ether 62:82:b2:1b:38:a6 brd ff:ff:ff:ff:ff:ff link-netnsid 0
inet 10.0.0.1/24 scope global eth0
valid_lft forever preferred_lft forever
3: lo: <BROADCAST,MULTICAST,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000
link/ether 94:04:a2:fb:a1:66 brd ff:ff:ff:ff:ff:ff link-netnsid 0
inet 172.17.0.2/16 brd 172.17.255.255 scope global eth1
valid_lft forever preferred_lft forever
```
From this we see that we will want to use `10.0.0.1` as our rendezvous address; we can choose any available port above 1000 (e.g. `5000`) for our rendezvous port.
Then, run `NCCL_SOCKET_IFNAME=eth0 python3 nccl_speedtest.py 10.0.0.1:5000 10G 0`&#x20;
The script will start, then, once it reaches `init_process_group` it will wait for the worker process on the other node to reach the same point and complete the rendezvous before proceeding.&#x20;
On the second instance, we run `NCCL_SOCKET_IFNAME=eth0 python3 nccl_speedtest.py 10.0.0.1:5000 10G 1`
Once we've done the script on the second instance reaches the TCP rendezvous, both processes will continue and start communicating over NCCL.&#x20;
# Ollama + Webui

# Ollama & WebUI Documentation
Below is a step-by-step guide on how to configure and run Ollama. Our template will automatically setup Open WebUI as a web based interface as well as expose a port for the Ollama API.
**R1** (deepseek-r1:70b) is used as the example model in this guide. Ollama has many [R1 models](https://ollama.com/library/deepseek-r1) available to use which the webui can download. The larger the model, the more total GPU RAM and disk space you will need to allocate when renting your GPU. The models page has a drop down menu showing the model name and total GPU RAM needed to run it. You will also need at least that much disk space on the instance.
## Find and rent your GPU
1. **Setup your Vast account and add credit:** Review the [quickstart guide](/documentation/get-started/quickstart) to get familar with the service if you do not have an account with credits loaded.
2. **Select the Ollama template:** click on [temp](https://cloud.vast.ai/templates/) and select the recommended Ollama template **Open Webui (Ollama).&#x20;**&#x43;lick on the play icon to select the template. You will then go to the search menu to find a GPU.&#x20;
* Click on the Readme link at any time for a detailed guide on how to use the template.
3. **Disk Space**: From the search menu, ensure you have **sufficient disk space** for the model(s) you plan to run. The disk slider is located under the template icon on the left hand column. Large models (e.g., 70B parameters) can require dozens of gigabytes of storage. For Deep Seek R1 70B, make sure to allocate 50GB of disk space using the slider.&#x20;
4. **VRAM Requirements**: Check that your **GPU VRAM** is sufficient for the model. Larger models require more VRAM. For Deep Seek R1 70B, we will need at least 43GB of VRAM. Find the slider titled GPU Total Ram and slide it ot 44GB.
5. **Example R1&#x20;**(deepseek-r1:70b): We recomend a 2X 4090 instance with 50GB of disk space.&#x20;
## Steps to Open the WebUI with Ollama
1. **After the instance loads, click the "Open" Button**
* This will initiate the Instance Portal with links to all the services running on the instance. Click the "Open WebUI" Link.
2. **Create an Admin Account**
* Upon first use (or if prompted), create an **Admin** username and password to secure your instance.
* You can add additional users in the Admin Panel
3. **Model Download**
* Click on the **admin panel -> settings**
* Click on the **Models** tab
* Click the download icon to **Manage Models**
* Put in the model name to pull directly from Ollama.com. For our example that would be: deepseek-r1:70b
* Wait for the model to fully download.
4. **Start a New Chat**
* Once the download is complete, return to the WebUI main page and start a new chat session.
* You can now test the model by sending prompts. Enjoy!
## Ollama API Usage
Ollama provides a direct API that you can call outside the WebUI. By default, it is available at:
```bash theme={null}
https://INSTANCE_IP:PORT_11434
```
### Authentication Token
* When making requests, you must include an **Authorization** header with the token value of OPEN\_BUTTON\_TOKEN.
* This token is typically displayed or stored in the WebUI settings or environment variable.
### Sample Curl Command
```bash theme={null}
curl -k https://INSTANCE_IP:EXTERNAL_PORT/v1/completions \
-H "Content-Type: application/json" \
-H "Authorization: Bearer OPEN_BUTTON_TOKEN" \
-d '{
"model": "deepseek-r1:70b",
"prompt": "San Francisco is a",
"max_tokens": 128,
"temperature": 0.6
}'
```
* -k: Allows curl to perform insecure SSL connections and transfers as Vast.ai uses a self-signed certificate.
* Replace **INSTANCE\_IP** and **EXTERNAL\_PORT** with the externally mapped port for 11434 from the IP button on the instance.
* Update the Authorization header value to match your **OPEN\_BUTTON\_TOKEN**. You can get that from any of the links in the Instance Portal or from the Open button on the instance card.
* Modify the prompt, model, and other fields (max\_tokens, temperature, etc.) as needed.
# Oobabooga (LLM webui)
Source: https://docs.vast.ai/oobabooga-llm-webui
A large language model(LLM) learns to predict the next word in a sentence by analyzing the patterns and structures in the text it has been trained on. This enables it to generate human-like text based on the input it receives.
There are many popular Open Source LLMs: Falcon 40B, Guanaco 65B, LLaMA and Vicuna. Hugging Face maintains [a leaderboard](https://huggingface.co/spaces/HuggingFaceH4/open_llm_leaderboard) of the most popular Open Source models that they have available.
[Oobabooga](https://github.com/oobabooga/text-generation-webui) is a front end that uses Gradio to serve a simple web UI for interacting with the Open Source model. In this guide, we will show you how to run an LLM using Oobabooga on Vast.
## 1) Setup your Vast account
The first thing to do if you are new to Vast is to create an account and verify your email address. Then head to the Billing tab and add credits. Vast uses Stripe to processes credit card payments and also accepts major cryptocurrencies through Coinbase or Crypto.com. \$20 should be enough to start. You can setup auto-top ups so that your credit card is charged when your balance is low.
## 2) Pick the Oobabooga template
Go to the [Templates tab](https://cloud.vast.ai/templates/) and search for "Oobabooga" among recommended templates and select it.
## 3) Allocate storage
The default storage amount will not be enough for downloading an LLM. Use the slider under the Instance Configuration to allocate more storage. 100GB should be enough.

You will need to understand how much GPU RAM the LLM requires before you pick a GPU. For example, the [Falcon 40B Instruct](https://huggingface.co/tiiuae/falcon-40b-instruct) model requires 85-100 GB of GPU RAM. Falcon 7B only requires 16GB. Other models do not have great documentation on how much GPU RAM they require. If the instance doesn't have enough GPU RAM, there will be an error when trying to load the model. You can use multiple GPUs in a single instance and add their GPU RAM together.
For this guide, we will load the Falcon 40B Instruct model on a 2X A6000 instance, which has 96GB of GPU RAM in total.

Any errrors loading the model will appear under the download button.
## 8) Start chatting!
Navigate to the Text generation tab to start chatting with the model. This is the most basic way to use Oobabooga, there are many other settings and things you can do with the interface.
## 9) Done? Destroy the instance
If you STOP the instance using the stop button, you will no longer pay the hourly GPU charges. **However you will still incur storage charges** because the data is still stored on the host machine. When you hit the START button to restart the instance, you are also not guaranteed that you can rent the GPU as someone else might have rented it while it was stopped.
To incur no other charges you have to DESTROY the instance using the trash can icon. **We recommend you destroy instances** so as not to incur storage charges while you are not using the system.
Have fun!

Verify your setup by executing these commands in Python's Interactive Shell in a Jupyter terminal:
```python icon="python" Python icon="python" Python theme={null}
import torch
print(f"PyTorch version: {torch.__version__}")
print(f"CUDA available: {torch.cuda.is_available()}")
print(f"GPU device: {torch.cuda.get_device_name(0)}")
```
### 2. Data Management
For efficient data handling:
a) Fast local storage:
```bash theme={null}
mkdir /workspace/data
cd /workspace/data
```
b) Dataset downloads:
```bash theme={null}
# Using wget
wget your_dataset_url
# Using git lfs for larger files: https://git-lfs.com/
sudo apt-get install git-lfs
git lfs install
git clone your_dataset_repo
```
## Training Best Practices
### Checkpoint Management
Always save checkpoints to prevent data loss:
```python icon="python" Python theme={null}
checkpoint_dir = '/workspace/checkpoints'
os.makedirs(checkpoint_dir, exist_ok=True)
checkpoint = {
'epoch': epoch,
'model_state_dict': model.state_dict(),
'optimizer_state_dict': optimizer.state_dict(),
'loss': loss,
}
torch.save(checkpoint, f'{checkpoint_dir}/checkpoint_{epoch}.pt')
```
### Resource Monitoring
Monitor GPU usage:
```bash theme={null}
watch -n 1 nvidia-smi
```
Or in Python:
```python icon="python" Python theme={null}
def print_gpu_utilization():
print(torch.cuda.memory_allocated() / 1024**2, "MB Allocated")
print(torch.cuda.memory_reserved() / 1024**2, "MB Reserved")
```
## Cost Optimization
### Instance Selection
* Use [vast cli search offers command ](https://vast.ai/docs/cli/commands#search-offers)to search for machines that fit your budget
* Monitor your spending in Vast.ai's Billing tab
### Resource Utilization
* Use appropriate batch sizes to maximize GPU utilization
* Enable gradient checkpointing for large models
* Implement early stopping to avoid unnecessary compute time
## Troubleshooting
### Common Issues and Solutions
* Out of Memory (OOM) Errors
* Reduce batch size
* Enable gradient checkpointing
* Use mixed precision training
```python icon="python" Python theme={null}
from torch.cuda.amp import autocast, GradScaler
scaler = GradScaler()
with autocast():
outputs = model(inputs)
loss = criterion(outputs, labels)
scaler.scale(loss).backward()
```
* Slow Training
* Check GPU utilization
* Verify data loading pipeline
* Consider using `torch.compile()` for PyTorch 2.0+
```python icon="python" Python theme={null}
model = torch.compile(model)
```
* Connection Issues
* Use `tmux` or `screen` for persistent sessions
* Set up automatic reconnection in your SSH config
## Best Practices
### Environment Management
* Document your setup and requirements
* Keep track of software versions
### Data Management
* Use data versioning tools
* Implement proper data validation

# Quantized GGUF models (cloned)
Source: https://docs.vast.ai/quantized-gguf-models-cloned
Here's a step-by-step guide to running quantized LLM models in multi-part GGUF format. We will use [Unsloth's Deepseek-R1 Q8\_0 model](https://huggingface.co/unsloth/DeepSeek-R1-GGUF) as an example. This model is very large and will require an 8xH200 machine configuration, but you can also follow this guide for much smaller models.
Before moving on with the guide,**&#x20;Setup your Vast account and add credit**. Review the [quickstart guide](/documentation/get-started/quickstart) to get familar with the service if you do not have an account with credits loaded.
## Llama.cpp
Llama.cpp is the recommended method for loading these models as it is able to directly load a split file of many parts without first merging them.
While it's easy to build llama.cpp inside one of our instances, we will focus on running this model in the Open WebUI template which contains a pre-compiled CUDA compatible versions of llama-server and llama-cli.&#x20;
## Open WebUI Template &#x20;
OpenWebui + Ollama is one of our recommended templates. While its default setup uses Ollama as a backend, it can also access an OpenAI-compatible API and it has been pre-configured to find one running on `http://localhost:20000`
A full guide to getting started with the OpenWebUI template is available [here](/ollama-webui)
Ensure you have enough disk space and a suitable configuration. For Deepseek-R1 Q8\_0 you'll need:
* At least 800GB VRAM
* 700GB storage space
The recommended configuration for this particular model is 8 x H200 with 750GB storage.
Once you have loaded up the template, you'll need to open up a terminal where we will pull and then serve the model.
### Pulling the model
You will want to download the models from the [Deepseek-R1 Q8\_0 model](https://huggingface.co/unsloth/DeepSeek-R1-GGUF) hugging face repo to the `/workspace/llama.cpp/models` directory on your instance. We have included a script with the [Ollama + Open WebUI](https://cloud.vast.ai?ref_id=62897\&template_id=d8aa06abd242979cee20d6646068167d) template that you may use to easily download the models.
```bash Bash theme={null}
llama-dl.sh --repo unsloth/DeepSeek-R1-GGUF --version Q8_0
```
This download will take some time as HuggingFace limits download speed, so even on an instance with very fast download speeds it may take up to an hour to completely download.
### Serving the model
Once the dowload has completed it's time to serve the model using the pre-built `llama-server` application.
Again, from the terminal, type the following:
```javascript JavaScript icon="js" theme={null}
llama-server \
--model /workspace/llama.cpp/models/DeepSeek-R1-Q8_0/DeepSeek-R1.Q8_0-00001-of-00015.gguf \
--ctx-size 8192 \
--n-gpu-layers 62 \
--port 20000
```
This command will load all of the model layers into GPU VRAM and begin serving the API at http\://localhost:20000
Once the model has finished loading to the GPU, it will be availabe directly from the OpenWebui interface in the model selector. Again, this may take some time to load and if you already have OpenWebui open then you may need to refresh the page.
## Building Llama.cpp
If you prefer to build llama.cpp yourself, you can simply run the following from any Vast-built template. The Recommended Nvidia CUDA template would be an ideal start.
```bash Bash theme={null}
apt-get install libcurl4-openssl-dev
git clone https://github.com/ggerganov/llama.cpp
cmake llama.cpp -B /tmp/llama.cpp/build \
-DBUILD_SHARED_LIBS=OFF -DGGML_CUDA=ON -DLLAMA_CURL=ON
cmake --build /tmp/llama.cpp/build --config Release -j --clean-first --target llama-quantize llama-cli llama-server llama-gguf-split
```
These commands will build the `llama-quantize` `llama-cli` `llama-server` and `llama-gguf-split` tools.
For advanced build instructions you should see the [official documentation](https://github.com/ggerganov/llama.cpp?tab=readme-ov-file#building-the-project) on GitHub.&#x20;
## Further Reading
Please see the template Readme for advanced template configuration, particularly if you would like to modify the template to make the llama-server API available externally with authentication or via a SSH tunnel.
# RTX 5 Series
Source: https://docs.vast.ai/rtx-5-series
Optimize your GPU experience with our comprehensive guide on RTX 5 Series GPUs (5090/5080/5070) and CUDA 12.8 compatibility. Learn how to rent an RTX 5090 on Vast.ai, select the right templates, and customize your storage while ensuring optimal performance.
## Renting RTX 5 Series GPUs (5090/5080/5070/5060)
Many of our recommended templates now support Blackwell series Nvidia GPU's including the RTX 5 series.
Blackwell GPUs do not have the same backwards compatibility as seen in some previous generation Nvidia GPU's so it is important that the template and Docker image has been configured to use CUDA 12.8 and PyTorch 2.7 or greater.
Any template that is known to be compatible with this GPU type will automatically show these GPUs in the offer listing. Those without support will exclude the unsupported cards when searching for an instance.
Templates configured with the `[Automatic]` tag will pull the most recent & supported docker image. This enables wider support across the range of GPUs you can find at Vast.ai
## Steps to Rent an RTX 5000 Series GPU on Vast.ai
1. **Create / Log in to your Vast.ai account**
Go to [cloud.vast.ai](https://cloud.vast.ai) and either create a new account or log in.
2. **Select a Recommended template with "\[Automatic]" set as the Version Tag (this is the default option).**
To check this, click the 'pencil' icon on the template card to open the template editor, you can view the image tag.

3. **Select the 5 series GPU from search filters**
In the GPU drop down menu select the specific 5 series card you want to rent or select the whole category.
<img src="https://mintcdn.com/vastai-80aa3a82/cNHQLqV42N4xE1uT/images/rtx-5-series-2.webp?fit=max&auto=format&n=cNHQLqV42N4xE1uT&q=85&s=9c9a4241a9756afd99a9606b59aed118" alt="" data-og-width="800" width="800" data-og-height="552" height="552" data-path="images/rtx-5-series-2.webp" data-optimize="true" data-opv="3" srcset="https://mintcdn.com/vastai-80aa3a82/cNHQLqV42N4xE1uT/images/rtx-5-series-2.webp?w=280&fit=max&auto=format&n=cNHQLqV42N4xE1uT&q=85&s=7c11ee8475015ffe46cd9cc4ce53c05f 280w, https://mintcdn.com/vastai-80aa3a82/cNHQLqV42N4xE1uT/images/rtx-5-series-2.webp?w=560&fit=max&auto=format&n=cNHQLqV42N4xE1uT&q=85&s=5d5fd2ad6b0aec6899f88f674762ac03 560w, https://mintcdn.com/vastai-80aa3a82/cNHQLqV42N4xE1uT/images/rtx-5-series-2.webp?w=840&fit=max&auto=format&n=cNHQLqV42N4xE1uT&q=85&s=2accb02127b7e747ca8568350b1f6704 840w, https://mintcdn.com/vastai-80aa3a82/cNHQLqV42N4xE1uT/images/rtx-5-series-2.webp?w=1100&fit=max&auto=format&n=cNHQLqV42N4xE1uT&q=85&s=50fb3122f6581767ab44bc98e53a8632 1100w, https://mintcdn.com/vastai-80aa3a82/cNHQLqV42N4xE1uT/images/rtx-5-series-2.webp?w=1650&fit=max&auto=format&n=cNHQLqV42N4xE1uT&q=85&s=64d8ceb9c18bc58ef7b9b4bee0ef2ce7 1650w, https://mintcdn.com/vastai-80aa3a82/cNHQLqV42N4xE1uT/images/rtx-5-series-2.webp?w=2500&fit=max&auto=format&n=cNHQLqV42N4xE1uT&q=85&s=55ea8365034ac5cb31ec0a2d4da51a21 2500w" />
4. **Review and customize**
Set your storage and further refine your search filters (e.g., secure cloud, location, system RAM, CPU, etc.). ⚠️ Do **not** change the Docker image because you need to maintain CUDA 12.8 and the dev version of PyTorch. If you switch to an incompatible Docker image, you may lose 5 series compatibility.
5. **Select and rent**
Click “Rent” next to your preferred server. You can now launch Jupyter notebooks, SSH into the instance, or start your own training jobs using the pre-installed CUDA 12.8 / PyTorch dev environment.
## Tips and Troubleshooting
* **Check CUDA version**: If you manually change the Docker image, ensure it’s compiled for CUDA 12.8 or else you may lose compatibility with these GPUs.
* **Stay up to date**: New PyTorch releases (especially nightlies / dev builds) often update their CUDA support. If you need a stable release, confirm that the Docker image tags match a stable version with CUDA 12.8.
* **Use custom Docker**: If you have your own Docker image, you must ensure it is built with CUDA 12.8 (and ideally tested on a GPU supporting that version).
# Python SDK Usage
Source: https://docs.vast.ai/sdk/python/quickstart
We provide a [PyPI package](https://pypi.org/project/vastai/), `vastai-sdk`, for convenient Python usage.
## PyPI Install
You can install the latest stable PyPI release with:
```text Text theme={null}
pip install vastai-sdk
```
## Usage
Import the package:
```text Text theme={null}

## Resource Methods
Most useful available VastAI resources are implemented. Commands for Vast CLI usage should have equivalent class methods on your Vast client object. Most IDEs should show type hints and relevant class methods and their expected arguments for `VastAI`, due to the implementation of our base class.
For example, the CLI command `vastai show instances` has the equivalent, `vast_sdk.show_instances()`.
```text Text theme={null}
from vastai_sdk import VastAI
vast_sdk = VastAI(api_key='YOUR_API_KEY')
output = vast_sdk.show_instances()
print(output)
```
## Example Usage
Here are some example usages of our Python SDK class `VastAI`:
### Starting and Stopping Instances
```text Text theme={null}
from vastai_sdk import VastAI
vast_sdk = VastAI(api_key='YOUR_API_KEY')
vast_sdk.start_instance(ID=12345678)
vast_sdk.stop_instance(ID=12345678)
```
### Creating a New Instance
Create a new instance based on given parameters (performs search offers + create instance).
```text Text theme={null}
from vastai_sdk import VastAI
vast_sdk = VastAI(api_key='YOUR_API_KEY')
vast_sdk.launch_instance(num_gpus="1", gpu_name="RTX_3090", image="pytorch/pytorch")
```
### Copying Files Between Instances

# Stable Diffusion
Source: https://docs.vast.ai/stable-diffusion
Stable Diffusion is a deep learning, text-to-image model that has been publicly released. It uses a variant of the diffusion model called latent diffusion. There are a few popular Open Source repos that create an easy to use web interface for typing in the prompts, managing the settings and seeing the images.
This guide will use the webui Github repo maintained by Automatic111 [here](https://github.com/AUTOMATIC1111/stable-diffusion-webui). The docker image used comes pre-loaded with Stable Diffusion v2.1, and it is possible to upload other models once you have the instance up and running. The recommend template will also setup Jupyter so you can use a web browser to download and upload files to the instance.
For all questions or issues with the web GUI, the project has a [readme](https://github.com/AUTOMATIC1111/stable-diffusion-webui) with links.
## 1) Setup your Vast account
The first thing to do if you are new to Vast is to create an account. Then head to the Billing tab and add credits. This is pretty self-explanatory. Vast uses Stripe to processes credit card payments and also accepts major cryptocurrencies through Crypto.com. \$20 should be enough to start. You pre-buy credits on Vast and then spend them down.
## 2) Pick the webui template
Click on the Change template button from the create page. Then click on the edit button on the Stable Diffusion template. We will need to set a username and password, so it is very important that we *edit* our template to set a username and password first.
<Frame caption="Stablediffusionedit">
![Stablediffusionedit](https://vast.ai/uploads/StableDiffusion/StableDiffusionEdit.png "Stablediffusionedit")
</Frame>
## 3) Set your username and password
>
To set your username and password, go to the beginning of the Docker Options and add the arguments
```text Text theme={null}
-e WEB_USER=YOUR_USERNAME -e WEB_PASSWORD=YOUR_PASSWORD
```
as shown below.
<Frame caption="Stablediffusionoptions">
![Stablediffusionoptions](https://vast.ai/uploads/StableDiffusion/StableDiffusionOptions.png)
</Frame>
You can also add the variables one by one in the env input
<Frame caption="Stablediffusionenv">
![Stablediffusionenv](https://vast.ai/uploads/StableDiffusion/StableDiffusionEnv.png)
</Frame>
## 4) Pick a GPU offer
Stable Diffusion can only run on a 1X GPU so select 1X from the filter menu on the top nav. This will then update the interface to show 1X GPU offers. Note that some Stable Diffusion models require large amounts of GPU VRAM. For max settings, you want more GPU RAM. Use the GPU RAM slider in the interface to find offers with over 20GB. We recommend an A6000, A40 or A100 if you want to max the Stable Diffusion settings.

</Frame>
If available, it is also best to pick a host with the datacenter label, as those machines are more reliable.
Click the blue RENT button to spin up the instance. You can then watch progress from the instance tab.
## 5) Connect and start making art
The instance can take 3-5 minutes to start. Once it is ready a blue connect button will appear. Click on that to open the web gui.
<Warning>
**WARNING**<br />
The web gui can take an additional 1-2 minutes to load. If you click on the connect button and get a blank page or error, simply wait 1-2 minutes and reload the page.
</Warning>
And there you go! Please read the [Automatic111 documentation](https://github.com/AUTOMATIC1111/stable-diffusion-webui) for how the web GUI works.
There are buttons to save and download the artwork, and also to zip it up.

## 6) Upload other model checkpoints
The recommended template has both SSH and Jupyter HTTPS launch modes enabled. To upload a model checkpoint, the simplest way is to click on the Jupyter button on the instances card to open Jupyter and then to upload the .ckpt file to the /workspace/stable-diffusion-webui/models/Stable-diffusion directory.
The Jupyter HTTPS launch mode will require you to install a certificate on your local machine. On macOS, this is not optional. Windows and Linux will show an error if the cert is not installed but there is a way to click through the error. To install the Jupyter certificate for Vast, follow the instructions [here](/documentation/instances/jupyter).
To use SSH, you will need to create an SSH key and upload the public portion to Vast. Learn more [here](/documentation/instances/sshscp).
For Linux/macOS users, SCP will also work.
## 7) Done? Destroy the instance
After you generate your artwork and are done with the instance, you have a few options. If you STOP the instance using the stop button, you will no longer pay the hourly GPU charges. **However you will still incur storage charges** because the data is still stored on the host machine. When you hit the START button to restart the instance, you are also not guaranteed that you can rent the GPU as someone else might have rented it while it was stopped. We don't recommend that you stop an instance once done.
To incur no other charges you have to DESTROY the instance using the trash can icon. **We recommend you destroy instances** so as not to incur storage charges while you are not using the system.
Have fun!

# Video Generation Guide: Using ComfyUI on Vast.ai
This guide will walk you through setting up and using ComfyUI for video generation on Vast.ai. ComfyUI provides a powerful node-based interface for creating advanced stable diffusion pipelines, making it ideal for video generation workflows.
## Prerequisites
* A Vast.ai account
* Basic familiarity with image or video generation models
* [(Optional) Read Jupyter guide](/documentation/instances/jupyter)
* [(Optional) SSH client installed on your local machine and SSH public key added in Account tab at cloud.vast.ai](/documentation/instances/sshscp)
## Setting Up Your Instance
### 1. Select the Right Template
Navigate to the Templates tab to view available templates. For video generation, we recommend searching for "ComfyUI" among the recommended templates. [The ComfyUI template](https://cloud.vast.ai/?ref_id=62897\&creator_id=62897\&name=ComfyUI) provides a powerful and modular stable diffusion GUI for designing and executing advanced pipelines using a graph/nodes/flowchart based interface.
**Template Features:**
* Access through both Jupyter and SSH
* Instance Portal
* Token-based authentication enabled by default
* Built-in provisioning script for models and custom nodes
### 2. **Edit your Template Configuration**
**Add/update these environment variables as needed:**
```bash Bash theme={null}
# Core Settings
COMFYUI_ARGS="--disable-auto-launch --port 18188 --enable-cors-header" # ComfyUI launch arguments
# Authentication
WEB_ENABLE_HTTPS=false # Enable/disable direct HTTPS
WEB_ENABLE_AUTH=true # Enable/disable authentication
# Access Tokens
CF_TUNNEL_TOKEN="" # Cloudflare Zero Trust token
CIVITAI_TOKEN="" # Access gated Civitai models
HF_TOKEN="" # Access gated HuggingFace models
# Custom Setup
PROVISIONING_SCRIPT="" # URL to custom provisioning script
```
**Provisioning Script:**
* Default script includes popular image models and custom nodes
* Fully customizable - Create your own script for a custom instance
* Must be Bash-compatible and start with `#!/bin/bash`
* Upload modified script to a GitHub Gist or respository and update the PROVISIONING\_SCRIPT variable to point to the raw file
<Warning>
**Important: Never save your template as public if you've included tokens or other secrets in the Docker Options field.**
</Warning>
Select your template from '[My Templates](https://cloud.vast.ai/templates/)' after making any desired edits to it.
### 3. Create Your Instance
1. In the [Search interface](https://cloud.vast.ai/create/), look for machines that have **sufficient VRAM** to handle your chosen video model. ⚠All models are different so check the model requirements carefully.
2. Click RENT to create an instance on the machine with the GPU of your choice
### 3. Connect to Your Instance
1. Go to [Instances tab](https://cloud.vast.ai/instances/) to see your instance loading
2. When the blue button says "OPEN", click this button to access the [Instance Portal](/documentation/instances/instance-portal) which will provide access to ComfyUI and other useful applications.
3. Click the direct link or cloudflare quick tunnel link to access ComfyUI. Here's a [beginner's guide to using ComfyUI](https://stable-diffusion-art.com/comfyui/).
### 4. Select a Video Workflow
ComfyUI has a workflow browser, so for a quick start you can choose on of their templates
<Frame caption="ComfyUI Workflows">

</Frame>
We'll pick the LTX Video workflow for this guide. Simply click it to proceed.
### 5. Download Missing Files
Your new instance will not yet have the required models, but fortunately ComfyUI will alert us to this and offer the models for download.
<img src="https://mintcdn.com/vastai-80aa3a82/LEwury95WvhzGW2f/images/use-cases-ai-video-generation-2.png?fit=max&auto=format&n=LEwury95WvhzGW2f&q=85&s=b11356de47a6b85046304819d2e8f93f" alt="ComfyUI template workflows" data-og-width="800" width="800" data-og-height="634" height="634" data-path="images/use-cases-ai-video-generation-2.png" data-optimize="true" data-opv="3" srcset="https://mintcdn.com/vastai-80aa3a82/LEwury95WvhzGW2f/images/use-cases-ai-video-generation-2.png?w=280&fit=max&auto=format&n=LEwury95WvhzGW2f&q=85&s=90b23d7efe224df2413e7cb90b2594ca 280w, https://mintcdn.com/vastai-80aa3a82/LEwury95WvhzGW2f/images/use-cases-ai-video-generation-2.png?w=560&fit=max&auto=format&n=LEwury95WvhzGW2f&q=85&s=7d178e1e0d718177447d44972a87c8d9 560w, https://mintcdn.com/vastai-80aa3a82/LEwury95WvhzGW2f/images/use-cases-ai-video-generation-2.png?w=840&fit=max&auto=format&n=LEwury95WvhzGW2f&q=85&s=eb0327ae5bf24a8846e36864aa56d4ae 840w, https://mintcdn.com/vastai-80aa3a82/LEwury95WvhzGW2f/images/use-cases-ai-video-generation-2.png?w=1100&fit=max&auto=format&n=LEwury95WvhzGW2f&q=85&s=449287dac3896af2456cdfa01f564c46 1100w, https://mintcdn.com/vastai-80aa3a82/LEwury95WvhzGW2f/images/use-cases-ai-video-generation-2.png?w=1650&fit=max&auto=format&n=LEwury95WvhzGW2f&q=85&s=923fbc1ad92eb52377eb671b521d6efc 1650w, https://mintcdn.com/vastai-80aa3a82/LEwury95WvhzGW2f/images/use-cases-ai-video-generation-2.png?w=2500&fit=max&auto=format&n=LEwury95WvhzGW2f&q=85&s=4e3956d83979beedf27e4b22c1b1384f 2500w" />
Unfortunately, the interface does not know it is running in the cloud so clicking the download buttons will download the models to your local machine. To work around this you can either:&#x20;
* Download the models to your computer and then upload them to the instance
* SSH to the instance and use `curl` or `wget` to directly download the models to their correct locations
To complete this guide we will use SSH
```bash Bash theme={null}
# Download the models
wget --content-disposition -P /workspace/ComfyUI/models/checkpoints/ "https://huggingface.co/Lightricks/LTX-Video/resolve/main/ltx-video-2b-v0.9.safetensors"
wget --content-disposition -P /workspace/ComfyUI/models/clip/ "https://huggingface.co/comfyanonymous/flux_text_encoders/resolve/main/t5xxl_fp16.safetensors"
# Download the workflow source image
wget --content-disposition -P /workspace/ComfyUI/input/ "https://comfyanonymous.github.io/ComfyUI_examples/ltxv/island.jpg"
```
The above commands will download the required models into the instance. When the downloads have completed you can refresh the browser window to clear the missing models error.
### 6. Run the Workflow
Finally, click the **Run** button to process the workflow.

# vLLM (LLM inference and serving)
Source: https://docs.vast.ai/vllm-llm-inference-and-serving
Below is a guide for runing the [vLLM template](https://cloud.vast.ai/?creator_id=62897\&name=vLLM) on Vast. The template contains everything you need to get started, so you will only need to specify the model you want to serve and the corresponding vLLM configuration.
For simplicity, we have set the default template model as [DeepSeek-R1-Distill-Llama-8B](https://huggingface.co/deepseek-ai/DeepSeek-R1-Distill-Llama-8B) with a limited context window because it can run on a single GPU with only 21GB VRAM, but vLLM can scale easily over multiple GPUs to handle much larger models.
## Set Up Your Account
1. **Setup your Vast account and add credit:** Review the [quickstart guide](/documentation/get-started/quickstart) to get familar with the service if you do not have an account with credits loaded.
## Configure the vLLM Template
vLLM serve is launched automatically by the template and it will use the configuration defined in the environment variables `VLLM_MODEL` and `VLLM_ARGS`. Here's how you can set it up
1. Vist the [templates](https://cloud.vast.ai/templates/) page and find the recommended vLLM template.
2. Click the pencil button to open up the template editor.
3. If you would like to run a model other than the default, edit the `VLLM_MODEL`environment variable. The default value is `deepseek-ai/DeepSeek-R1-Distill-Llama-8B` which is a HuggingFace repository.
4. You can also set the arguments to pass to `vllm serve` by modifying the `VLLM_ARGS` environment variable. vLLM is highly configurable so it's a good idea to check the official documentation before changing anything here. All available startup arguments are listed in the [official vLLM documentation](https://docs.vllm.ai/en/latest/serving/engine_args.html).
5. Save the template. You will be able to find the version you have just modified in the templates page in the 'My Templates' section.
## Launch Your Instance
1. **Select the template** you just saved from the 'My Templates' section of the templates page.
2. Click the **Play icon** on this template to be taken to view the available offers.
3. Use the search filters to select a suitable GPU, ensuring that you have **sufficient VRAM** to load all of the model's layers to GPU.
4. From the search menu, ensure you have **sufficient disk space** for the model you plan to run. The disk slider is located under the template icon on the left hand column. Large models (e.g., 70B parameters) can require dozens of gigabytes of storage. For Deep Seek R1 8B, make sure to allocate over 17Gb of disk space using the slider.&#x20;
5. Click **Rent** on a suitable instance and wait for it to load
Once the instance has loaded you'll be able to click the Open button to access the instance portal where you'll see links to the interactive vLLM API documentation and the Ray control panel.
As vLLM must download your model upon first run it may take some time before the API is available. You can follow the startup progress in the instance logs.&#x20;
## vLLM API Usage
The vLLM API can be accessed programmatically at:
```bash Bash theme={null}
https://INSTANCE_IP:PORT_8000
```
### Authentication Token
* When making requests, you must include an **Authorization** header with the token value of OPEN\_BUTTON\_TOKEN.
### Sample Curl Command
```bash Bash theme={null}
curl -k https://INSTANCE_IP:EXTERNAL_PORT/v1/completions \
-H "Content-Type: application/json" \
-H "Authorization: Bearer 7b040f8d37017016a336a804a8039068d7c744850f3a441db48d6da559379058" \
-d '{
"model": "deepseek-ai/DeepSeek-R1-Distill-Llama-8B",
"prompt": "San Francisco is a",
"max_tokens": 128,
"temperature": 0.6
}'
```
* -k: Allows curl to perform insecure SSL connections and transfers as Vast.ai uses a self-signed certificate.
* Replace **INSTANCE\_IP** and **EXTERNAL\_PORT** with the externally mapped port for 8000 from the IP button on the instance.
* Update the Authorization header value to match your **OPEN\_BUTTON\_TOKEN**. You can get that from any of the links in the Instance Portal or from the Open button on the instance card.
* Modify the prompt, model, and other fields (max\_tokens, temperature, etc.) as needed.
## vLLM with Python
Although the instance starts the vllm serve function to provide an inference API, the template has been configured with Jupyter and SSH access so you can also interact with vLLM in code from your instance. To do this simply include the vllm modules at the top of your Python script:
```python icon="python" Python theme={null}
from vllm import LLM, SamplingParams
```
## Further Reading
Please see the template Readme file on our recommended vLLM template for advanced template configuration and other methods of connecting to and interacting with your instance.
# VMs
Source: https://docs.vast.ai/vms
<Warning>
**WARNING:**
VMs interface much more directly with hardware than Docker containers.
Proper VM support is very sensitive to hardware setup.
This guide covers the configuration steps needed to enable support for Vast VMs on most setups, but is not and cannot be exhausitve.
</Warning>
# Introduction
Vast now supports VM instances running on Kernel Virtual Machine (KVM) in addition to Docker container based instances.
VM support is currently an optional feature for hosts as it usually requires additional configuration steps on top of those needed to support Docker-based instances.
Host machines are not required to be VM compatible; the Vast hosting software will automatically test and enable the feature on machines on which VMs are supported.
On new machines the tests will be run on install; for machines configured before the VM-feature release, testing for VM-compatability will happen when the machine is unoccupied.
Machines that do not have VM support enabled will be hidden in the search page for clients who have VM-based templates selected.
## VM Support Benefits/Drawbacks
### Benefits
VM support will allow your machine to take advantage of demand for use cases that Docker cannot easily support, in addition to demand for conventional Docker-based instances.
VMs support the following features/use-cases that Docker-based instances do not:
<Columns cols={2}>
<p>Feature</p>
<p>Use-case</p>
</Columns>
Systemd/Docker
Multi-Application Server Tooling and DevOps (e.g., Docker Compose, Kubernetes, Docker Build)
Non-Linux OSes
Windows Graphics (e.g., for rendering or cloud gaming)
ptrace
Program analysis for CUDA-performance optimization (e.g., via Nvidia NSight)
Currently no other peer-to-peer GPU rental marketplace offers full VMs; instead full VMs are only available from traditional providers at much higher costs.
Thus we believe that hosts who have VMs enabled can expect to command a substantial preumium.
### Drawbacks
* Due to greater user control over hardware, VM support requires IOMMU settings for securing PCIe communications that can degrade the performance of NCCL on non-RTX 40X0 multi-GPU machines that rely on PCI-based GPU peer-to-peer communication.
* VMs require more disk space than Docker containers as they do not share components with the host OS. Hosts with VMs enabled may want to set higher disk and internet bandwidth prices.
### Summary
We recommend all hosts with single-GPU rigs to try to ensure VM support as the drawbacks for single-GPU machines are minimal.
We also generally recommend multi-GPU Hosts with RTX 40X0 series GPUs try enabling VMs, especially if they have plentiful disk space and fast (500Mbps+) internet speed,
as rendering/gaming users will benefit from those, as well as users who need multi-application orchestration tools.
We do not recommend multi-GPU hosts with datacenter GPUs enable VMs until we can ensure better GPU P2P communication support in VMs, including support for NVLink.
## Configuring VMs on your machine
### Checking VM enablement status.
Run `python3 /var/lib/vastai_kaalia/enable_vms.py check`.
Possible results are:
* `on`: VMs are enabled on your machine.
* `off`: VMs are disabled on your machine. Either you disabled VMs or our previous tests failed.
* `pending`: VMs are not disabled, but will try to enable once the machine is idle.
### Disabling VMs.
To prevent VMs from being enabled on your machine, or to disable VMs after they have been enabled, run `python3 /var/lib/vastai_kaalia/enable_vms.py off`.
Note that default configuration settings for most machines will not support VMs, and we can detect that, so most hosts who do not want VMs enabled do not need to take any action.
### Configuring your machine to support VMs.
### Hardware prerequisites
You will require a CPU and a chipset that support Intel VT-d or AMD-Vi.
### Configure BIOS
Check that virtualization is enabled in your BIOS. On most machines, this should be enabled by default.
### Configure Kernel Commandline Arguments
For further reference refer to [Preparing the IOMMU](https://ubuntu.com/server/docs/gpu-virtualization-with-qemu-kvm#preparing-the-input-output-memory-management-unit-iommu).
We will need to ensure IOMMU, a technology that secures and isolates communication between PCIe devices, is set up, along with disabling all driver features that interfere with VMs.
Open `/etc/default/grub` and add to the `GRUB_CMDLINE_LINUX=` the following:
* `amd_iommu=on` or `intel_iommu=on` depending on whether you have an AMD or Intel CPU.
* `nvidia_drm.modeset=0`
Some hosts may also need to add the following settings:
* `rd.driver.blacklist=nouveau`
* `modprobe.blacklist=nouveau`
Then run `sudo update-grub` and reboot.
### Disable display managers/background GPU processes.
If you have a display manager (e.g., GDM) or display server (XOrg, Wayland, etc) running, you must disable them.
You may not run any background GPU processes for VMs to work (`nvidia-persitenced` is OK, it is managed by our hosting software).
### Enabling VMs
We will check/test your configuration when your machine is idle and enable VMs by default if your machine is capable of supporting VMs, and you have not set VMs to `off`.
If you have VMs set to off, and you'd like to retry enabling VMs, run `sudo python3 /var/lib/vastai_kaalia/enable_vms.py on -f` while your machine is idle.
