ChatGPT and Codex will share one usage allowance from December
OpenAI says that from December, Plus, Pro and Business plans will have one usage allowance shared across ChatGPT and Codex. The change comes as OpenAI brings the agent features of Work into the main ChatGPT experience. Usage will be counted in tokens.
How fast you use the allowance will depend on the model and the task. OpenAI says more advanced models and complex tasks generally use more, and that Instant chat will not count against it. The company expects most people will not wait for a reset more often than they do now.
You will see your combined remaining usage and reset times in Settings, under Usage. At the limit, you can wait for the reset, upgrade your plan, or buy credits for eligible features.
What it means for your work
- If you use both ChatGPT and Codex: Heavy coding in Codex can now use up the same allowance you need for long tasks in ChatGPT. Plan big jobs around your reset times.
- For quick questions: Use Instant chat, which will not draw from the allowance.
- If you buy seats for a team: Check Settings, then Usage, in the first weeks of December to see whether people hit the limit. That tells you whether a higher plan or credits pay off.
This follows OpenAI's larger Work and Codex allowance on Pro and Business Premium in late October.
