+## Normal Mode
+
+The initial version uses a single model to accomplish all tasks. This model needs to support function calling and must allow for a sufficiently large tool description length, ideally greater than 1754. If the model used in this mode does not support KV Cache, it will consume a significant number of tokens.
+
+![normal mode](https://github.com/musistudio/claude-code-reverse/blob/main/screenshoots/normal.png)
+
+## Router Mode
+
+Using multiple models to handle different tasks, this mode requires setting ENABLE_ROUTER to true and configuring four models: ROUTER_AGENT_MODEL, TOOL_AGENT_MODEL, CODER_AGENT_MODEL, and THINK_AGENT_MODEL.
+
+ROUTER_AGENT_MODEL does not require high intelligence and is only responsible for request routing. A small model is sufficient for this task (testing has shown that the qwen-coder-3b model performs well).
+TOOL_AGENT_MODEL must support function calling and allow for a sufficiently large tool description length, ideally greater than 1754. If the model used in this mode does not support KV Cache, it will consume a significant number of tokens.
+
+CODER_AGENT_MODEL and THINK_AGENT_MODEL can use the DeepSeek series of models.
+
+The purpose of router mode is to separate tool invocation from coding tasks, enabling the use of inference models like r1, which do not support function calling.
