this is the actual build for a second Codex app that can run the AI models you choose.

get the repo, every command and the copy-paste setup prompt free inside Codex Club: https://www.skool.com/codexclub

someone copied my post word for word, including the same screenshot, so Episode Zero shows the method they left out.

in the video, i build the three parts that make it work:

- an isolated second Codex app on Mac, or separate profiles on Windows and Linux

- a local proxy that translates the Responses API for other model providers

- a model catalog for OpenRouter and Ollama

OpenRouter gives you more cloud-model choice, but you still pay and your data travels. Ollama gives you a local, private and per-token-free path, but your hardware decides how usable it is.

no magic. no “trust me.” just the build.
