# AI Provider Setup Guide
Step-by-step setup for each AI provider with TheSys C1, including current model IDs, pricing, and specifications.
---
## OpenAI
```typescript
import OpenAI from "openai";
const client = new OpenAI({
baseURL: "https://api.thesys.dev/v1/embed",
apiKey: process.env.THESYS_API_KEY,
});
```
### Available Models
**Stable (Production)**:
- `c1/openai/gpt-5/v-20250930` - GPT 5
- Input: $2.50/M | Output: $12.50/M
- Context: 380K | Max Output: 128K
**Experimental**:
- `c1-exp/openai/gpt-4.1/v-20250617` - GPT 4.1
- Input: $4.00/M | Output: $10.00/M
- Context: 1M | Max Output: 32K
### Example Usage
```typescript
const response = await client.chat.completions.create({
model: "c1/openai/gpt-5/v-20250930",
messages: [
{ role: "system", content: "You are a helpful assistant." },
{ role: "user", content: "Create a product comparison table." }
],
stream: true,
temperature: 0.7,
max_tokens: 2000
});
```
---
## Anthropic (Claude)
```typescript
// Same OpenAI client! TheSys handles the conversion
const client = new OpenAI({
baseURL: "https://api.thesys.dev/v1/embed",
apiKey: process.env.THESYS_API_KEY,
});
```
### Available Models
**Stable (Production)**:
- `c1/anthropic/claude-sonnet-4/v-20250930` - Claude Sonnet 4
- Input: $6.00/M | Output: $18.00/M
- Context: 180K | Max Output: 64K
**Experimental**:
- `c1-exp/anthropic/claude-3.5-haiku/v-20250709` - Claude 3.5 Haiku
- Input: $1.60/M | Output: $5.00/M
- Context: 180K | Max Output: 8K
**Deprecated** (not recommended):
- `c1/anthropic/claude-sonnet-3-5`
- `c1/anthropic/claude-3.7-sonnet`
### Example Usage
```typescript
const response = await client.chat.completions.create({
model: "c1/anthropic/claude-sonnet-4/v-20250930",
messages: [
{ role: "system", content: "You are Claude, an AI assistant." },
{ role: "user", content: "Generate a data visualization chart." }
],
stream: true,
temperature: 0.8,
max_tokens: 4096
});
```
---
## Cloudflare Workers AI
### Option 1: Workers AI Only (No C1)
Use Workers AI directly for cost optimization on simple use cases.
```typescript
const aiResponse = await env.AI.run('@cf/meta/llama-3-8b-instruct', {
messages: [
{ role: "system", content: "You are a helpful assistant." },
{ role: "user", content: "Hello!" }
]
});
```
### Option 2: Hybrid Approach (Workers AI + C1)
Use Workers AI for processing, then TheSys C1 for UI generation.
```typescript
// Step 1: Process with Workers AI (cheap)
const analysis = await env.AI.run('@cf/meta/llama-3-8b-instruct', {
messages: [{ role: "user", content: "Analyze this data..." }]
});
// Step 2: Generate UI with C1 (interactive components)
const c1Response = await fetch("https://api.thesys.dev/v1/embed/chat/completions", {
method: "POST",
headers: {
"Authorization": `Bearer ${env.THESYS_API_KEY}`,
"Content-Type": "application/json"
},
body: JSON.stringify({
model: "c1/openai/gpt-5/v-20250930",
messages: [
{
role: "system",
content: "Create a chart visualization for this data."
},
{
role: "user",
content: analysis.response
}
]
})
});
```
**Cost Benefits**:
- Workers AI: Very low cost for text generation
- C1 API: Only used for final UI generation
- Combined: Best of both worlds
---
## Python Backend (FastAPI/Flask)
```python
import openai
import os
client = openai.OpenAI(
base_url="https://api.thesys.dev/v1/embed",
api_key=os.getenv("THESYS_API_KEY")
)
```
### Example with TheSys SDK
```python
from thesys_genui_sdk import with_c1_response, write_content
@app.post("/api/chat")
@with_c1_response
async def chat(request: dict):
stream = client.chat.completions.create(
model="c1/anthropic/claude-sonnet-4/v-20250930",
messages=[
{"role": "system", "content": "You are a helpful assistant."},
{"role": "user", "content": request["prompt"]}
],
stream=True
)
for chunk in stream:
content = chunk.choices[0].delta.content
if content:
yield write_content(content)
```
See `templates/python-backend/` for complete examples.
---
## Model Selection Guide
### When to Use Each Provider
**GPT 5** (`c1/openai/gpt-5/v-20250930`):
- Best for: General-purpose applications
- Pros: Large context window (380K), lower cost
- Cons: Less nuanced than Claude for some tasks
**Claude Sonnet 4** (`c1/anthropic/claude-sonnet-4/v-20250930`):
- Best for: Complex reasoning, code generation
- Pros: Superior code understanding, detailed responses
- Cons: Higher cost, smaller context window
**Experimental Models** (`c1-exp/...`):
- Best for: Testing new features, non-production use
- Pros: Access to cutting-edge capabilities
- Cons: May have unexpected behavior, pricing subject to change
---
## Environment Variables
```bash
# Required
THESYS_API_KEY=sk-th-your-api-key-here
# Optional (for CORS configuration)
ALLOWED_ORIGINS=http://localhost:5173,https://your-domain.com
```
Get your API key: https://console.thesys.dev/keys
---
## Version Notes
Model version identifiers (e.g., `v-20250930`) may change as new versions are released. Always check the [TheSys Playground](https://console.thesys.dev/playground) for the latest available versions.

# Common Errors & Solutions
Complete troubleshooting guide for TheSys C1 Generative UI integration.
---
## 1. Empty Agent Responses
**Symptom**: AI returns empty responses, UI shows nothing or blank content.
**Causes**:
- Incorrect streaming transformation
- Response not properly extracted from API
- Empty content in stream chunks
**Solutions**:
```typescript
// ✅ Correct - use transformStream with fallback
import { transformStream } from "@crayonai/stream";
const c1Stream = transformStream(llmStream, (chunk) => {
return chunk.choices[0]?.delta?.content || ""; // Empty string fallback
});
// ❌ Wrong - no fallback
const c1Stream = transformStream(llmStream, (chunk) => {
return chunk.choices[0].delta.content; // May be undefined
});
```
**Verification**:
```bash
# Check API response format
curl -X POST https://api.thesys.dev/v1/embed/chat/completions \
-H "Authorization: Bearer $THESYS_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"c1/openai/gpt-5/v-20250930","messages":[{"role":"user","content":"test"}]}'
```
---
## 2. Model Not Following System Prompt
**Symptom**: AI ignores instructions, doesn't follow guidelines in system prompt.
**Cause**: System prompt is not first in messages array or formatted incorrectly.
**Solution**:
```typescript
// ✅ Correct - system prompt FIRST
const messages = [
{ role: "system", content: "You are a helpful assistant." }, // MUST BE FIRST
...conversationHistory,
{ role: "user", content: userPrompt },
];
// ❌ Wrong - system prompt after user messages
const messages = [
{ role: "user", content: "Hello" },
{ role: "system", content: "..." }, // TOO LATE
];
// ❌ Wrong - no system prompt at all
const messages = [
{ role: "user", content: userPrompt },
];
```
---
## 3. Version Compatibility Errors
**Symptom**: `TypeError: Cannot read property 'X' of undefined`, component crashes.
**Cause**: Mismatched package versions between SDK and API.
**Compatibility Matrix**:
| C1 API Version | @thesysai/genui-sdk | @crayonai/react-ui | @crayonai/react-core |
|----------------|--------------------|--------------------|---------------------|
| v-20250930 | ~0.6.40 | ~0.8.42 | ~0.7.6 |
**Solution**:
```bash
# Check current versions
npm list @thesysai/genui-sdk @crayonai/react-ui @crayonai/react-core
# Update to compatible versions (October 2025)
npm install @thesysai/genui-sdk@0.6.40 @crayonai/react-ui@0.8.42 @crayonai/react-core@0.7.6
```
---
## 4. Theme Not Applying
**Symptom**: UI components don't match custom theme, default styles persist.
**Cause**: Missing `ThemeProvider` wrapper.
**Solution**:
```typescript
// ❌ Wrong - no ThemeProvider
<C1Component c1Response={response} />
// ✅ Correct - wrapped with ThemeProvider
<ThemeProvider theme={customTheme}>
<C1Component c1Response={response} />
</ThemeProvider>
// ✅ Also correct - for C1Chat
<C1Chat apiUrl="/api/chat" theme={customTheme} />
```
---
## 5. Streaming Not Working
**Symptom**: UI doesn't update in real-time, waits for full response.
**Causes**:
- `stream: false` in API call
- Missing proper headers
- Not passing `isStreaming` prop
**Solutions**:
```typescript
// 1. Enable streaming in API call
const stream = await client.chat.completions.create({
model: "c1/openai/gpt-5/v-20250930",
messages: [...],
stream: true, // ✅ IMPORTANT
});
// 2. Set proper response headers (Next.js)
return new NextResponse(responseStream, {
headers: {
"Content-Type": "text/event-stream",
"Cache-Control": "no-cache, no-transform",
"Connection": "keep-alive",
},
});
// 3. Pass isStreaming prop
<C1Component
c1Response={response}
isStreaming={true} // ✅ Shows loading indicator
updateMessage={(msg) => setResponse(msg)}
/>
```
---
## 6. Tool Calling Failures
**Symptom**: Tools not executing, validation errors, or crashes.
**Causes**:
- Invalid Zod schema
- Missing descriptions
- Incorrect tool format
- Arguments not parsed correctly
**Solutions**:
```typescript
import { z } from "zod";
import zodToJsonSchema from "zod-to-json-schema";
// ✅ Proper schema with descriptions
const toolSchema = z.object({
query: z.string().describe("Search query"), // DESCRIBE all fields!
limit: z.number().int().min(1).max(100).describe("Max results"),
});
// ✅ Convert to OpenAI format
const tool = {
type: "function" as const,
function: {
name: "search_web",
description: "Search the web for information", // Clear description
parameters: zodToJsonSchema(toolSchema), // Convert schema
},
};
// ✅ Validate incoming tool calls
try {
const args = toolSchema.parse(JSON.parse(toolCall.function.arguments));

}
}
```

## 7. Thread State Not Persisting
**Symptom**: Threads disappear on page refresh, conversation history lost.
**Cause**: Using in-memory storage instead of database.
**Solution**:
```typescript
// ❌ Wrong - loses data on restart
const messageStore = new Map<string, Message[]>();
// ✅ Correct - use database (D1 example)
import { db } from "./database";
export async function saveMessage(threadId: string, message: Message) {
await db.insert(messages).values({
threadId,
role: message.role,
content: message.content,
createdAt: new Date(),
});
}
export async function getThreadMessages(threadId: string) {
return db
.select()
.from(messages)
.where(eq(messages.threadId, threadId))
.orderBy(messages.createdAt);
}
```
---
## 8. CSS Conflicts
**Symptom**: Styles from C1 components clash with app styles, layout breaks.
**Cause**: CSS import order or global styles overriding.
**Solution**:
```typescript
// ✅ Correct import order
import "@crayonai/react-ui/styles/index.css"; // C1 styles FIRST
import "./your-app.css"; // Your styles SECOND
// In your CSS, use specificity if needed
.your-custom-class .c1-message {
/* Override specific styles */
background-color: var(--custom-bg);
}
// Avoid global overrides
/* ❌ Wrong - too broad */
* {
margin: 0;
padding: 0;
}
/* ✅ Better - scoped */
.app-container * {
margin: 0;
padding: 0;
}
```
---
## 9. TypeScript Type Errors
**Symptom**: TypeScript complains about missing types or incompatible types.
**Solutions**:
```bash
# 1. Update packages
npm install @thesysai/genui-sdk@latest @crayonai/react-ui@latest
# 2. Check tsconfig.json
{
"compilerOptions": {
"moduleResolution": "bundler", // or "node16"
"skipLibCheck": true, // Skip type checking for node_modules
"types": ["vite/client", "node"]
}
}
# 3. If still errors, regenerate types
rm -rf node_modules package-lock.json
npm install
```
---
## 10. CORS Errors
**Symptom**: `Access-Control-Allow-Origin` errors when calling API.
**Solutions**:
```typescript
// Next.js API Route
export async function POST(req: NextRequest) {
const response = new NextResponse(stream, {
headers: {
"Access-Control-Allow-Origin": "*", // Or specific domain
"Access-Control-Allow-Methods": "POST, OPTIONS",
"Access-Control-Allow-Headers": "Content-Type",
},
});
return response;
}
// Express
import cors from "cors";
app.use(cors({
origin: "http://localhost:5173", // Your frontend URL
methods: ["POST", "OPTIONS"],
}));
// Cloudflare Workers (Hono)
import { cors } from "hono/cors";
app.use("/*", cors({
origin: "*",
allowMethods: ["POST", "OPTIONS"],
}));
```
---
## 11. Rate Limiting Issues
**Symptom**: API calls fail with 429 errors, no retry mechanism.
**Solution**:
```typescript
async function callApiWithRetry(
apiCall: () => Promise<any>,
maxRetries: number = 3
) {
for (let i = 0; i < maxRetries; i++) {
try {
return await apiCall();
} catch (error: any) {
if (error.status === 429 && i < maxRetries - 1) {
const waitTime = Math.pow(2, i) * 1000; // Exponential backoff
console.log(`Rate limited. Waiting ${waitTime}ms...`);
await new Promise((resolve) => setTimeout(resolve, waitTime));
continue;
}
throw error;
}
}
}
// Usage
const response = await callApiWithRetry(() =>
client.chat.completions.create({...})
);
```
---
## 12. Authentication Token Errors
**Symptom**: `401 Unauthorized` even with API key set.
**Solutions**:
```bash
# 1. Verify environment variable is set
echo $THESYS_API_KEY # Should show your key
# 2. Check .env file location and format
# .env (in project root)
THESYS_API_KEY=your_api_key_here
# 3. For Vite, use VITE_ prefix for client-side
VITE_THESYS_API_KEY=your_key # Client-side
THESYS_API_KEY=your_key # Server-side
# 4. For Cloudflare Workers, use secrets
npx wrangler secret put THESYS_API_KEY
# 5. Verify in code
if (!process.env.THESYS_API_KEY) {
throw new Error("THESYS_API_KEY is not set");
}
```
---
## 13. Invalid Model ID Error
**Symptom**: API returns 400 error: "Model not found" or "Invalid model ID".
**Causes**:
- Using outdated model version identifier
- Typo in model name
- Using deprecated model
- Wrong prefix (`c1/` vs `c1-exp/`)
**Solutions**:
```typescript
// ❌ Wrong - old version
model: "c1/anthropic/claude-sonnet-4/v-20250617"
// ✅ Correct - current stable version (as of Oct 2025)
model: "c1/anthropic/claude-sonnet-4/v-20250930"
// ❌ Wrong - non-existent models
model: "c1/openai/gpt-5-mini" // Doesn't exist
model: "c1/openai/gpt-4o" // Not available via C1
// ✅ Correct - actual models
model: "c1/openai/gpt-5/v-20250930" // GPT 5 stable
model: "c1-exp/openai/gpt-4.1/v-20250617" // GPT 4.1 experimental
// ❌ Wrong - deprecated
model: "c1/anthropic/claude-sonnet-3-5"
model: "c1/anthropic/claude-3.7-sonnet"
// ✅ Correct - current stable
model: "c1/anthropic/claude-sonnet-4/v-20250930"
```
**Current Stable Models** (October 2025):
| Provider | Model ID | Status |
|----------|----------|--------|
| Anthropic | `c1/anthropic/claude-sonnet-4/v-20250930` | ✅ Stable |
| OpenAI | `c1/openai/gpt-5/v-20250930` | ✅ Stable |
| OpenAI | `c1-exp/openai/gpt-4.1/v-20250617` | ⚠️ Experimental |
| Anthropic | `c1-exp/anthropic/claude-3.5-haiku/v-20250709` | ⚠️ Experimental |
**How to Find Latest Models**:
1. Visit [TheSys Playground](https://console.thesys.dev/playground)
2. Check the model dropdown for current versions
3. Look for `v-YYYYMMDD` format in the model ID
4. Prefer stable (`c1/`) over experimental (`c1-exp/`) for production
**Verification**:
```bash
# Test if model ID works
curl -X POST https://api.thesys.dev/v1/embed/chat/completions \
-H "Authorization: Bearer $THESYS_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "c1/anthropic/claude-sonnet-4/v-20250930",
"messages": [{"role": "user", "content": "test"}]
}'
```

# Python Backend Templates for TheSys Generative UI
This directory contains production-ready Python backend templates for integrating TheSys C1 Generative UI API.
## Available Templates
### 1. FastAPI Backend (`fastapi-chat.py`)
Modern async web framework with automatic API documentation.
**Features**:
- Async streaming support
- Built-in request validation with Pydantic
- Automatic OpenAPI docs
- CORS middleware configured
- Type hints throughout
**Run**:
```bash
# Install dependencies
pip install -r requirements.txt
# Set environment variable
export THESYS_API_KEY=sk-th-your-key-here
# Run server
python fastapi-chat.py
# Or with uvicorn directly
uvicorn fastapi-chat:app --reload --port 8000
```
**API Docs**: Visit `http://localhost:8000/docs` for interactive API documentation
---
### 2. Flask Backend (`flask-chat.py`)
Lightweight and flexible web framework.
**Features**:
- Simple and familiar Flask API
- CORS support with flask-cors
- Streaming response handling
- Easy to customize and extend
**Run**:
```bash
# Install dependencies
pip install -r requirements.txt
# Set environment variable
export THESYS_API_KEY=sk-th-your-key-here
# Run server
python flask-chat.py
# Or with flask CLI
export FLASK_APP=flask-chat.py
flask run --port 5000
```
---
## Setup
### 1. Install Dependencies
```bash
# Create virtual environment
python -m venv venv
source venv/bin/activate # On Windows: venv\Scripts\activate
# Install all dependencies
pip install -r requirements.txt
# OR install only what you need
pip install thesys-genui-sdk openai python-dotenv
# For FastAPI
pip install fastapi uvicorn
# For Flask
pip install flask flask-cors
```
### 2. Environment Variables
Create a `.env` file:
```bash
THESYS_API_KEY=sk-th-your-api-key-here
```
Get your API key from: https://console.thesys.dev/keys
### 3. Choose Your Model
Both templates use different models by default to show variety:
**FastAPI**: Uses Claude Sonnet 4
```python
model="c1/anthropic/claude-sonnet-4/v-20250930"
```
**Flask**: Uses GPT 5
```python
model="c1/openai/gpt-5/v-20250930"
```
Change to any supported model:
- `c1/anthropic/claude-sonnet-4/v-20250930` - Claude Sonnet 4 (stable)
- `c1/openai/gpt-5/v-20250930` - GPT 5 (stable)
- `c1-exp/openai/gpt-4.1/v-20250617` - GPT 4.1 (experimental)
- `c1-exp/anthropic/claude-3.5-haiku/v-20250709` - Claude 3.5 Haiku (experimental)
---
## Frontend Integration
### React + Vite Example
```typescript
const makeApiCall = async (prompt: string) => {
const response = await fetch("http://localhost:8000/api/chat", {
method: "POST",
headers: { "Content-Type": "application/json" },
body: JSON.stringify({ prompt })
});
const reader = response.body?.getReader();
const decoder = new TextDecoder();
while (true) {
const { done, value } = await reader.read();
if (done) break;
const chunk = decoder.decode(value);
setC1Response(prev => prev + chunk);
}
};
```
### Next.js API Route (Proxy)
```typescript
// app/api/chat/route.ts
export async function POST(req: Request) {
const { prompt } = await req.json();
const response = await fetch("http://localhost:8000/api/chat", {
method: "POST",
headers: { "Content-Type": "application/json" },
body: JSON.stringify({ prompt })
});
return new Response(response.body, {
headers: {
"Content-Type": "text/event-stream",
"Cache-Control": "no-cache"
}
});
}
```
---
## Production Deployment
### Environment Variables
```bash
# Production
THESYS_API_KEY=sk-th-production-key
HOST=0.0.0.0
PORT=8000
ENVIRONMENT=production
ALLOWED_ORIGINS=https://your-frontend.com
```
### FastAPI (Recommended for Production)
```bash
# Install production server
pip install gunicorn
# Run with Gunicorn
gunicorn fastapi-chat:app \
--workers 4 \
--worker-class uvicorn.workers.UvicornWorker \
--bind 0.0.0.0:8000 \
--timeout 120
```
### Flask Production
```bash
# Install production server
pip install gunicorn
# Run with Gunicorn
gunicorn flask-chat:app \
--workers 4 \
--bind 0.0.0.0:5000 \
--timeout 120
```
### Docker Example
```dockerfile
FROM python:3.12-slim
WORKDIR /app
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt
COPY fastapi-chat.py .
ENV THESYS_API_KEY=""
ENV PORT=8000
CMD ["uvicorn", "fastapi-chat:app", "--host", "0.0.0.0", "--port", "8000"]
```
---
## Troubleshooting
### Common Issues
**1. Import Error: `thesys_genui_sdk` not found**
```bash
pip install thesys-genui-sdk
```
**2. CORS Errors**
Update CORS configuration in the template to match your frontend URL:
```python
allow_origins=["http://localhost:5173"] # Vite default
```
**3. Streaming Not Working**
Ensure:
- `stream=True` in the API call
- Using `@with_c1_response` decorator
- Proper response headers set
**4. Authentication Failed (401)**
Check that `THESYS_API_KEY` is set correctly:
```python
import os
print(os.getenv("THESYS_API_KEY")) # Should not be None
```
---
## Next Steps
1. Copy the template you want to use
2. Install dependencies from `requirements.txt`
3. Set your `THESYS_API_KEY` in `.env`
4. Run the server
5. Connect your React frontend
6. Customize the system prompt and model as needed
For more examples, see the main SKILL.md documentation.
