# Claude Code Router

> This is a repository for testing routing Claude Code requests to different models.

![demo.png](https://github.com/musistudio/claude-code-reverse/blob/main/screenshoots/demo.png)

## Warning! This project is for testing purposes and may consume a lot of tokens! It may also fail to complete tasks!

## Implemented

- [x] Using the qwen2.5-coder-3b-instruct model as the routing dispatcher (since it’s currently free on Alibaba Cloud’s official website)

- [x] Using the qwen-max-0125 model as the tool invoker

- [x] Using deepseek-v3 as the coder model

- [x] Using deepseek-r1 as the reasoning model

Thanks to the free qwen2.5-coder-3b-instruct model from Alibaba and deepseek’s KV-Cache, we can significantly reduce the cost of using Claude Code. Make sure to set appropriate ignorePatterns for the project. See: https://docs.anthropic.com/en/docs/agents-and-tools/claude-code/overview
