CodeMuxHow does multi-model routing work?
Planning, implementation, and review can each run on a different model. Routing is automatic by default, so you never have to switch providers by hand between steps.
Models & providers
GPT, Claude, DeepSeek, and Grok in one coding workflow.
CodeMux ships with a managed catalog from OpenAI, Anthropic, DeepSeek, and xAI. Automatic routing picks a suitable model for each step of a task; set preferences when you want to decide yourself.
Catalog snapshot reviewed . The catalog inside the extension is always the current one.
Managed model catalog

Availability, limits, and compatibility can change. A model being listed does not mean every task or step will use it.
Can I use my own API provider?
Yes, if the endpoint is compatible. Compatibility depends on the endpoint and model, so not every API service is supported. Your provider bills those requests directly. See how managed and API billing differ.
Is CodeMux made by a model provider?
No. CodeMux is an independent product, not affiliated with or endorsed by OpenAI, Anthropic, DeepSeek, xAI, or Microsoft. Read the product facts and privacy notice.
