# ![Mistral 標誌](https://models.dev/logos/mistral.svg)Mistral

透過 Mastra 的模型路由器存取 33 個 Mistral 模型。系統會自動使用 `MISTRAL_API_KEY` 環境變數進行驗證。

詳情請參閱[Mistral 文件](https://docs.mistral.ai/getting-started/models/)。

```bash
MISTRAL_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: 'mistral/codestral-latest',
})

// 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)
}
```

## 進階設定

### 自訂標頭

```typescript
const agent = new Agent({
  id: 'custom-agent',
  name: 'custom-agent',
  model: {
    url: 'https://api.mistral.ai/v1',
    id: 'mistral/codestral-latest',
    apiKey: process.env.MISTRAL_API_KEY,
    headers: {
      'X-Custom-Header': 'value',
    },
  },
})
```

### 動態選擇模型

```typescript
const agent = new Agent({
  id: 'dynamic-agent',
  name: 'Dynamic Agent',
  model: ({ requestContext }) => {
    const useAdvanced = requestContext.task === 'complex'
    return useAdvanced ? 'mistral/voxtral-small-latest' : 'mistral/codestral-latest'
  },
})
```

## 直接安裝 Provider

此 Provider 亦可直接安裝為獨立套件，用來取代 Mastra 模型路由器字串。詳情請參閱[套件文件](https://www.npmjs.com/package/@ai-sdk/mistral)。

**npm**:
