1. 双模型服务 (llm + smallLLM) - 增加 get_small_llm_service() 函数 - 支持智谱/DeepSeek 小模型作为轻量级选项 2. 前置混合路由 - 规则快速分流(无 LLM,超快速) - 轻量级意图分类(smallLLM) - 快速路径:fast_chitchat, fast_rag, fast_tool 3. 自动升级机制 - 快速路径失败 → 自动回到 React 循环 - SSE 事件增强:intent_classified, path_decision, fast_path_*, escalation 4. 向后兼容 - build_react_main_graph(use_hybrid_router=True/False) - 可选择启用或禁用混合路由 5. 更新 intent.py - 支持 use_small_llm 参数 - 保留原有完整功能供 React 循环使用
