Access 7 ModelScope models through Mastra's model router. Authentication is handled automatically using the `MODELSCOPE_API_KEY` environment variable.

Learn more in the [ModelScope documentation](https://modelscope.cn/docs/model-service/API-Inference/intro).

```bash
MODELSCOPE_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: "modelscope/Qwen/Qwen3-235B-A22B-Instruct-2507"
});

// 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 [ModelScope documentation](https://modelscope.cn/docs/model-service/API-Inference/intro) for details.
