# ![Perplexity logo](https://models.dev/logos/perplexity.svg)당황

Mastra의 Model 라우터를 통해 4가지 Perplexity Model에 액세스하세요. 인증은 다음을 사용하여 자동으로 처리됩니다.`PERPLEXITY_API_KEY` environment variable.

자세한 내용은 다음에서 확인하세요.[Perplexity documentation](https://docs.perplexity.ai).

```bash
PERPLEXITY_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: "perplexity/sonar"
});

// 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);
}
```

## 고급 구성

### 맞춤 헤더

```typescript
const agent = new Agent({
  id: "custom-agent",
  name: "custom-agent",
  model: {
    id: "perplexity/sonar",
    apiKey: process.env.PERPLEXITY_API_KEY,
    headers: {
      "X-Custom-Header": "value"
    }
  }
});
```

### 동적 Model 선택

```typescript
const agent = new Agent({
  id: "dynamic-agent",
  name: "Dynamic Agent",
  model: ({ requestContext }) => {
    const useAdvanced = requestContext.task === "complex";
    return useAdvanced
      ? "perplexity/sonar-reasoning-pro"
      : "perplexity/sonar";
  }
});
```
