Mastra의 Model 라우터를 통해 21개의 Snowflake Cortex Model에 액세스하세요. 인증은 `SNOWFLAKE_CORTEX_PAT` 환경 변수를 사용하여 자동으로 처리됩니다. `SNOWFLAKE_ACCOUNT`도 구성하세요. 자세한 내용은 다음에서 확인하세요.[Snowflake Cortex documentation](https://docs.snowflake.com/en/user-guide/snowflake-cortex/cortex-rest-api).

```bash
SNOWFLAKE_ACCOUNT=your-value
SNOWFLAKE_CORTEX_PAT=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: "snowflake-cortex/claude-fable-5"
});

// 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);
}
```

> **정보:** Mastra는 OpenAI 호환 `/chat/completions` 엔드포인트를 사용합니다. 일부 Provider별 기능은 제공되지 않을 수 있습니다. 자세한 내용은 [Snowflake Cortex 문서](https://docs.snowflake.com/en/user-guide/snowflake-cortex/cortex-rest-api)를 확인하세요.

## 고급 구성

### 맞춤 헤더

```typescript
const agent = new Agent({
  id: "custom-agent",
  name: "custom-agent",
  model: {
    url: "https://${SNOWFLAKE_ACCOUNT}.snowflakecomputing.com/api/v2/cortex/v1",
    id: "snowflake-cortex/claude-fable-5",
    apiKey: process.env.SNOWFLAKE_CORTEX_PAT,
    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
      ? "snowflake-cortex/snowflake-llama3.3-70b"
      : "snowflake-cortex/claude-fable-5";
  }
});
```
