ChatGPT and Codex will share one usage allowance from December as Work moves into Chat
OpenAI says that starting in December, Plus, Pro and Business plans will draw ChatGPT and Codex usage from one shared allowance measured in tokens, as it brings the agent features of the Work tab into the main ChatGPT experience.
What happened
- OpenAI's help center says Plus, Pro and Business usage allowances will be shared across ChatGPT and Codex starting in December.
- Usage will be measured in tokens, so more advanced models and complex tasks use more of the allowance, while Instant chat will not count against it.
- Combined remaining usage and reset times will show in Settings, Usage; at the limit, users can wait for a reset, upgrade or buy credits for eligible features.
- An email to users, reported by TechCrunch, says a merged Chat and Work experience in the ChatGPT desktop app will reach select users first, and Codex stays a separate section.
Why it matters: If you lean on both ChatGPT and Codex on the same plan, heavy use of one will now eat into the other. OpenAI says most users won't hit resets more often, but it's worth watching Settings, Usage once the change lands.
