Access 103 Pioneer models through Mastra's model router. Authentication is handled automatically using the `PIONEER_API_KEY` environment variable.

Learn more in the [Pioneer documentation](https://agent.pioneer.ai/llms.txt).

```bash
PIONEER_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: "pioneer/HuggingFaceTB/SmolLM3-3B-Base"
});

// 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);
}
```

> **Note:** Mastra uses the OpenAI-compatible `/chat/completions` endpoint. Some provider-specific features may not be available. Check the [Pioneer documentation](https://agent.pioneer.ai/llms.txt) for details.
