## Using Custom Models

For models not in the built-in list (fine-tuned, preview, or new releases), specify the provider explicitly:

```typescript theme={null}
// Fine-tuned OpenAI model
const result = await tracia.runLocal({
  model: 'ft:gpt-4o:my-org:custom:abc123',
  provider: 'openai',
  messages: [{ role: 'user', content: 'Hello!' }]
});

// New Anthropic model not yet in the list
const result = await tracia.runLocal({
  model: 'claude-5-opus-20260101',
  provider: 'anthropic',
  messages: [{ role: 'user', content: 'Hello!' }]
});
```

<Warning>
  When using custom models, always specify the `provider` parameter to ensure the correct SDK is used.
