+# AI 答题配置接口文档
+
+## 概述
+
+AI 答题功能用于在刷课过程中自动完成作业任务点。系统支持多种 AI 服务商，管理员可以通过配置接口设置 AI 参数。
+
+核心代码位于 `internal/application/quesbank` 包，提供通用的题库答题能力，可被不同平台（学习通、智慧教育等）复用。
+

+## AI 服务商配置指南
+
+### 智谱AI (ChatGLM)
+
+1. 访问 [智谱AI开放平台](https://open.bigmodel.cn/)
+2. 注册并创建 API Key
+3. 配置参数：
+   - type: `chatglm`
+   - model: `glm-4` 或 `glm-3-turbo`
+   - apiKey: 你的 API Key
+
+### 讯飞星火
+
+1. 访问 [讯飞开放平台](https://www.xfyun.cn/)
+2. 创建应用并获取 API Key
+3. 配置参数：
+   - type: `xinghuo`
+   - model: `generalv3.5` 或其他版本
+   - apiKey: 你的 API Key
+
+### 通义千问
+
+1. 访问 [阿里云百炼](https://dashscope.aliyun.com/)
+2. 开通服务并获取 API Key
+3. 配置参数：
+   - type: `tongyi`
+   - model: `qwen-plus` 或 `qwen-turbo`
+   - apiKey: 你的 API Key
+
+### 豆包
+
+1. 访问 [火山引擎](https://www.volcengine.com/)
+2. 开通豆包大模型服务
+3. 配置参数：
+   - type: `doubao`
+   - model: 你的模型端点 ID
+   - apiKey: 你的 API Key
+
+### OpenAI
+
+1. 访问 [OpenAI Platform](https://platform.openai.com/)
+2. 创建 API Key
+3. 配置参数：
+   - type: `openai`
+   - model: `gpt-3.5-turbo` 或 `gpt-4`
+   - apiKey: 你的 API Key
+
+### 其他兼容服务
+
+支持任何兼容 OpenAI API 格式的服务（如 DeepSeek、Moonshot 等）。
+
+配置参数：
+- type: `other`
+- url: API 地址（如 `https://api.deepseek.com/v1/chat/completions`）
+- model: 模型名称
+- apiKey: 你的 API Key
+
+---
+
+## 使用说明
+
+1. 配置 AI 后，系统在执行刷课任务时会自动使用 AI 完成作业任务点
+2. 作业答案默认仅保存不提交，需要用户手动确认后提交
+3. 如果未配置 AI，作业任务点将被跳过
+4. 建议先使用测试接口验证配置是否正确
+
+## 错误码
+
+| 错误码 | 说明 |
+|--------|------|
+| 400 | 参数错误或配置不完整 |
+| 403 | 无权限操作 |
+| 500 | 服务器内部错误 |
