 14. 🔄 支持Rerank模型，目前兼容Cohere和Jina，可接入Dify，[对接文档](Rerank.md)
 15. ⚡ **[OpenAI Realtime API](https://platform.openai.com/docs/guides/realtime/integration)** - 支持OpenAI的Realtime API，支持Azure渠道
 16. 支持使用路由/chat2link 进入聊天界面
+17. 🧠 支持通过模型名称后缀设置 reasoning effort：
+    - 添加后缀 `-high` 设置为 high reasoning effort (例如: `o3-mini-high`)
+    - 添加后缀 `-medium` 设置为 medium reasoning effort (例如: `o3-mini-medium`)
+    - 添加后缀 `-low` 设置为 low reasoning effort (例如: `o3-mini-low`)
