# 推理

> Responses API Beta 支援進階推理能力,讓模型在回答問題時展示其內部推理過程,推理強度可透過參數設定。

## 推理設定

您可以使用 `reasoning` 參數設定推理行為:

```shellscript theme={null}
curl -X POST https://aihubmix.com/v1/responses \
  -H "Authorization: Bearer YOUR_AIHUBMIX_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "glm-5",
    "input": "Plan a week-long trip to the US for me.",
    "reasoning": {
      "effort": "high"
    },
    "max_output_tokens": 5000
  }'
```

## 推理強度

`effort` 參數控制模型投入推理的運算資源量,實質上決定了推理強度。

| 推理強度    | 說明              |
| :------ | :-------------- |
| minimal | 基本推理,使用最少運算     |
| low     | 輕量推理,適合簡單問題     |
| medium  | 平衡推理,適合中等複雜度的問題 |
| high    | 深度推理,適合複雜問題     |

## 在對話中使用推理

推理功能也可以在多輪對話中使用:

```python theme={null}
import requests

url = "https://aihubmix.com/v1/responses"

headers = {
    "Authorization": "Bearer YOUR_AIHUBMIX_API_KEY",
    "Content-Type": "application/json",
}

data = {
    "model": "kimi-k2.5",
    "input": [
        {
            "type": "message",
            "role": "user",
            "content": [
                {
                    "type": "input_text",
                    "text": "What is your favorite animal?",
                }
            ],
        },
        {
            "type": "message",
            "role": "assistant",
            "id": "msg_123",
            "status": "completed",
            "content": [
                {
                    "type": "output_text",
                    "text": "I don't have a favorite animal.",
                    "annotations": []
                }
            ],
        },
        {
            "type": "message",
            "role": "user",
            "content": [
                {
                    "type": "input_text",
                    "text": "Why is the sky blue?",
                }
            ],
        },
    ],
    "reasoning": {
        "effort": "high"
    },
    "max_output_tokens": 5000,
}

response = requests.post(url, headers=headers, json=data)

print(response.status_code)
print(response.json())
```

## 包含推理資訊的回應

啟用推理後,API 傳回的結果會包含推理資料:

## 使用建議

1. **選擇合適的推理強度**:複雜問題使用 `high`,簡單任務使用 `low`。
2. **考量 token 使用量**:推理會增加 token 消耗。
3. **善用串流輸出**:對於較長的推理鏈,串流可以提升使用者體驗。
4. **提供上下文**:給模型足夠的上下文以實現有效推理。
