## Integration with AI SDK
Use the model ID directly with OpenRouter:
```typescript
import { createOpenRouter } from "@openrouter/ai-sdk-provider";
const openrouter = createOpenRouter({ apiKey: process.env.OPENROUTER_API_KEY });
const model = openrouter("google/gemini-2.0-flash-exp:free");
```

## Data Freshness
Model data is synced from OpenRouter every 2 days. Last sync timestamp is in the `generated_at` field.
