# ![Lilac 标志](https://models.dev/logos/lilac.svg)Lilac

通过 Mastra 的模型路由器访问 4 个 Lilac 模型。系统会自动使用 `LILAC_API_KEY` 环境变量完成身份验证。

更多信息请参阅[Lilac 文档](https://docs.getlilac.com)。

```bash
LILAC_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: 'lilac/google/gemma-4-31b-it',
})

// 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)
}
```

> **信息:** Mastra 使用兼容 OpenAI 的 `/chat/completions` endpoint。部分 Provider 特有功能可能不可用，详情请参阅[Lilac 文档](https://docs.getlilac.com)。

## 模型

| Model                         | Context | Tools | Reasoning | Image | Audio | Video | Input $/1M | Output $/1M |

## 高级配置

### 自定义请求头

```typescript
const agent = new Agent({
  id: 'custom-agent',
  name: 'custom-agent',
  model: {
    url: 'https://api.getlilac.com/v1',
    id: 'lilac/google/gemma-4-31b-it',
    apiKey: process.env.LILAC_API_KEY,
    headers: {
      'X-Custom-Header': 'value',
    },
  },
})
```

### 动态选择模型

```typescript
const agent = new Agent({
  id: 'dynamic-agent',
  name: 'Dynamic Agent',
  model: ({ requestContext }) => {
    const useAdvanced = requestContext.task === 'complex'
    return useAdvanced ? 'lilac/zai-org/glm-5.2' : 'lilac/google/gemma-4-31b-it'
  },
})
```
