## Parameter Guidelines

### temperature
- **0.0**: Deterministic, focused
- **1.0**: Balanced (default)
- **2.0**: Very creative, random

### topP (nucleus sampling)
- **0.95**: Default, good balance
- Lower = more focused

### topK
- **40**: Default
- Higher = more diversity

### maxOutputTokens
- Always set this to prevent excessive generation
- Max: 65,536 tokens

## Use Cases

**Factual tasks**: temperature=0.0, topP=0.8
**Creative tasks**: temperature=1.2, topP=0.95
**Code generation**: temperature=0.3, topP=0.9
