OpenAI Codex Update Tracker

OpenAI Codex is turning into a super app. When Google announced 3.5, the OpenAI team immediately implemented a code red in the company and launched several updates. With GPT-5.5, or possibly 5.6, coming in the next few months, GPT is currently one of the best models. OpenAI Codex is also one of the best tools you can use.

Moreover, OpenAI is rolling out Codex updates every week, adding new features and new functionalities. In this AI era, it is hard to keep track of every update from these apps. So to make it easy for you, we have been tracking all the updates coming to OpenAI Codex.
