A curated list of pages for anyone searching for open ai codex (written OpenAI Codex by the vendor): the coding agent that runs in ChatGPT, as a desktop app and in the cloud, plus the developer side where you build on the OpenAI API. Entries are grouped so the ChatGPT route, the developer route and the business pages do not get mixed up, and each link carries a one-line reason to open it.
