# ![Bailing 標誌](https://models.dev/logos/bailing.svg)Bailing

透過 Mastra 的模型路由器存取 2 個 Bailing 模型。系統會自動使用 `BAILING_API_TOKEN` 環境變數進行驗證。

詳情請參閱[Bailing 文件](https://alipaytbox.yuque.com/sxs0ba/ling/intro)。

```bash
BAILING_API_TOKEN=your-api-token
```

```typescript
import { Agent } from '@mastra/core/agent'

const agent = new Agent({
  id: 'my-agent',
  name: 'My Agent',
  instructions: 'You are a helpful assistant',
  model: 'bailing/Ling-1T',
})

// 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)
}
```

> **資訊:** Mastra 使用與 OpenAI 相容的 `/chat/completions` 端點。部分 Provider 專屬功能可能無法使用，詳情請參閱[Bailing 文件](https://alipaytbox.yuque.com/sxs0ba/ling/intro)。

## 模型

| Model             | Context | Tools | Reasoning | Image | Audio | Video | Input $/1M | Output $/1M |
| ----------------- | ------- | ----- | --------- | ----- | ----- | ----- | ---------- | ----------- |
| `bailing/Ling-1T` | 128K    |       |           |       |       |       | $0.57      | $2          |
| `bailing/Ring-1T` | 128K    |       |           |       |       |       | $0.57      | $2          |

## 進階設定

### 自訂標頭

```typescript
const agent = new Agent({
  id: 'custom-agent',
  name: 'custom-agent',
  model: {
    url: 'https://api.tbox.cn/api/llm/v1/chat/completions',
    id: 'bailing/Ling-1T',
    apiKey: process.env.BAILING_API_TOKEN,
    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 ? 'bailing/Ring-1T' : 'bailing/Ling-1T'
  },
})
```
