Access 3 Morph models through Mastra's model router. Authentication is handled automatically using the `MORPH_API_KEY` environment variable.

Learn more in the [Morph documentation](https://docs.morphllm.com).

```bash
MORPH_API_KEY=your-api-key
```

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

const agent = new Agent({
  name: "my-agent",
  instructions: "You are a helpful assistant",
  model: "morph/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 [Morph documentation](https://docs.morphllm.com) for details.
