ChatGPT and Codex to share the same usage limit starting in December

If you use both ChatGPT and the coding tool Codex, you will have to draw on the same usage limit for both starting in December. OpenAI announced the change in a newsletter to users and in a post on the company's developer forum.

The shared limit applies to the Plus, Pro and Business plans. According to OpenAI, it is part of the effort to bring Work into Chat. Codex will remain a separate experience in ChatGPT's desktop app, however.

How the limit is used

How much of your limit you use depends on the model and the task. More advanced models and complex tasks eat up more of the limit than simple ones. Unlimited use of Instant, which is included in the plan, does not count against the limit.

You can see your total remaining limit and the reset times under Settings → Usage.

If you use up your entire limit, you can wait for it to reset, upgrade your plan or buy credits to keep using the features it covers.

OpenAI expects that most users will not have to wait for a reset any more often than they do today. The company also says it is preparing the transition carefully so that it does not disrupt users' work.

Chat and Work combined in test

In the coming weeks, OpenAI will begin testing a combined experience of the Chat and Work tabs with a small group of users. The feedback will be used to improve the experience before it is rolled out more widely.

In the combined experience, you can bring your files and plugins along and ask ChatGPT to build a website, create a presentation or carry out tasks on the web while you follow and guide the work. According to OpenAI, this makes it possible to go from exploring an idea to having ChatGPT bring it to life, all in one place.

Size unclear

OpenAI has not said how large the shared limit will be for each plan, or on which day in December the switch will happen.
