Access 17 Scaleway models through Mastra's model router. Authentication is handled automatically using the `SCALEWAY_API_KEY` environment variable.

Learn more in the [Scaleway documentation](https://www.scaleway.com/en/docs/generative-apis/).

```bash
SCALEWAY_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: "scaleway/bge-multilingual-gemma2"
});

// 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);
}
```
