OpenAI said in its official help documentation that ChatGPT and Codex usage quotas will be unified starting in December for the Plus, Pro, and Business plans.

Why it matters

Tying chat and coding into one token budget means heavy use in one place directly reduces what is left for the other, and OpenAI has not yet said when the switch happens or how large each plan's allowance will be.

ChatGPT and Codex Will Share One Usage Quota Starting in December

Key Facts

  • OpenAI will unify ChatGPT and Codex usage quotas starting in December for the Plus, Pro, and Business plans.
  • Only chats through Instant will not consume usage under the unified quota.
  • Usage is measured in tokens, and more advanced models and complex tasks consume more of the quota.
  • Conversations and coding share one quota, so usage in one affects the remaining quota for the other.
  • Remaining usage and reset time can be checked under Usage in Settings.

Usage is counted in tokens, and more advanced models and complex tasks draw down more of the shared allowance. Chats through Instant will not consume usage. Remaining quota and the reset time can be checked under Usage in Settings.

The change covers the Plus, Pro, and Business tiers. Because conversations and coding draw from the same pool, time spent in one reduces the remaining quota for the other, and the help page does not yet give a switchover date or the size of each plan's quota.

OpenAI lists three ways to keep going after hitting the limit: wait for the reset, change plans, or buy credits for the feature in question. Usage is measured in tokens, the unit of information the model processes and generates, so heavier models and more complex tasks cost more of the allowance.
