 | **云端SaaS版** | (默认) 产品部署在公有云，用户通过浏览器按需订阅使用。 | 必须支持多租户、高可用。 |
 | **私有化部署** | (医院/机构) 将**整个平台**或**指定模块**（如DC, SSA）部署在客户的内网服务器上。 | 必须提供容器化（Docker/K8s）的一键部署方案。数据100%不出内网。 |
-| **混合部署** | (私有化客户) 客户在内网使用"私有化"的DC/SSA模块，同时能调用我们"云端"的ASL/AIA模块。 | 平台必须支持这种"本地+云端"的混合调用模式，前端需智能路由。 |
 | **单机版** | (个人医生) 提供**可安装的桌面应用(Windows/Mac)**，针对DC、SSA、ASL等核心模块。 | **数据100%本地化**。文献、病例原始文件严禁上传。必须支持离线运行（如DC, SSA）。 *(例外：ASL模块可受控调用云端LLM，但仅限发送"摘要"而非"原文")* |
