CodeMux

CodeMux is a VS Code extension that helps developers plan, implement, and review coding tasks using multiple AI models, including GPT, Claude, DeepSeek, and Grok. It routes each step of a task to the model best suited for it, then presents the resulting diff, checks performed, and cost in one place. Users can fund a managed balance or connect their own API. The extension is free to install, with no subscription or seat fee, and charges only for model usage. It's designed to keep developers in control, letting them inspect changes and verify results before accepting them.
