# ![Model Oracle AI logo](https://models.dev/logos/model-oracle-ai.svg)Model Oracle AI

Access 15 Model Oracle AI models through Mastra's model router. Authentication is handled automatically using the `MODEL_ORACLE_API_KEY` environment variable.

Learn more in the [Model Oracle AI documentation](https://modeloracle.com/setup/).

```bash
MODEL_ORACLE_API_KEY=your-api-key
```

```typescript
import { Agent } from "@mastra/core/agent";

const agent = new Agent({
  id: "my-agent",
  name: "My Agent",
  instructions: "You are a helpful assistant",
  model: "model-oracle-ai/auto"
});

// Generate a response
const response = await agent.generate("Hello!");

// Stream a response
const stream = await agent.stream("Tell me a story");
for await (const chunk of stream) {
  console.log(chunk);
}
```

> **Info:** Mastra uses the OpenAI-compatible `/chat/completions` endpoint. Some provider-specific features may not be available. Check the [Model Oracle AI documentation](https://modeloracle.com/setup/) for details.
