 ## 当前功能
 
-- **模型库**：启动时自动扫描模型目录（可手动重新扫描），支持导入本地 GGUF、添加 OpenAI 兼容在线 API 模型（聊天时可直接选用）
+- **模型管理**：启动时自动扫描模型目录（可手动重新扫描），支持导入本地 GGUF、添加 OpenAI 兼容在线 API 模型；本地模型可一键「部署」后台加载，部署成功后对话页可直接选用
 - **模型广场**：搜索 Hugging Face / ModelScope 上的 GGUF 模型，按量化版本一键下载（ModelScope 文件自动附带 SHA256 校验），下载进度实时显示
 - **聊天**：流式输出、Markdown/代码高亮、采样参数调节、多会话管理；本地模型与在线 API 模型统一入口
 - **本地 API 服务**：OpenAI 兼容端点（/v1/models、/v1/chat/completions、/v1/embeddings），仅本机监听，可选 API Key
