# Model Selection

Switch between different AI models to optimize for speed, capability, or cost.

## What are Models?

Models are different versions of the AI with varying capabilities:

- **Larger models**: More capable, better reasoning, slower, higher cost
- **Smaller models**: Faster responses, lower cost, good for simpler tasks

## Changing Models

1. Open the chat panel
2. Look for the **model dropdown** below the input field
3. Select the desired model from the available options

## Model Persistence

The selected model persists for the current session. Your preference is remembered across sessions.

## Cost Considerations

When using API keys, different models have different pricing. Check your provider's pricing page for current rates.
