Access 21 NanoGPT models through Mastra's model router. Authentication is handled automatically using the `NANO_GPT_API_KEY` environment variable.

Learn more in the [NanoGPT documentation](https://docs.nano-gpt.com).

```bash
NANO_GPT_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: "nano-gpt/deepseek/deepseek-r1"
});

// 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);
}
```

Mastra uses the OpenAI-compatible `/chat/completions` endpoint. Some provider-specific features may not be available. Check the [NanoGPT documentation](https://docs.nano-gpt.com) for details.

## Advanced Configuration

### Custom Headers

```typescript
const agent = new Agent({
  id: "custom-agent",
  name: "custom-agent",
  model: {
    url: "https://nano-gpt.com/api/v1",
    id: "nano-gpt/deepseek/deepseek-r1",
    apiKey: process.env.NANO_GPT_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
      ? "nano-gpt/zai-org/glm-4.7:thinking"
      : "nano-gpt/deepseek/deepseek-r1";
  }
});
