Access 25 TensorX models through Mastra's model router. Authentication is handled automatically using the `TENSORX_API_KEY` environment variable.

Learn more in the [TensorX documentation](https://docs.tensorx.ai/).

```bash
TENSORX_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: "tensorx/deepseek/deepseek-chat-v3.1"
});

// 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 [TensorX documentation](https://docs.tensorx.ai/) for details.

## Advanced configuration

### Custom headers

```typescript
const agent = new Agent({
  id: "custom-agent",
  name: "custom-agent",
  model: {
    url: "https://api.tensorx.ai/v1",
    id: "tensorx/deepseek/deepseek-chat-v3.1",
    apiKey: process.env.TENSORX_API_KEY,
    headers: {
      "X-Custom-Header": "value"
    }
  }
});
```

### Dynamic model selection

```typescript
const agent = new Agent({
  id: "dynamic-agent",
  name: "Dynamic Agent",
  model: ({ requestContext }) => {
    const useAdvanced = requestContext.task === "complex";
    return useAdvanced
      ? "tensorx/z-ai/glm-5v-turbo"
      : "tensorx/deepseek/deepseek-chat-v3.1";
  }
});
