What it's for

  • use a cheaper model behind a coding CLI you already know
  • route different kinds of request to different models automatically
  • keep using Codex when the model you want is somewhere else

We have checked the project site of opencodex 157 times since 15 Sept 2026, and the site answered every time. The site's visible text last changed on 1 Nov 2026.

What it does

A provider proxy that sits between OpenAI Codex or Claude Code and the model actually answering, so either can run on a different LLM. It covers the Codex CLI, app, SDK and model picker, with model routing, provider combinations, sidecars for search and vision, image and video bridges, a web dashboard and a management API.

Evidence

Each bar is one request to the project's own site

This one is installed and run on your own machine, so what we re-check is the project’s site — whether it is still published and still reachable. We cannot tell you from here that the tool itself runs.
