OpenAI to merge ChatGPT and Codex usage limits in December
OpenAI's help center says Plus, Pro and Business subscribers will share a single usage allowance across ChatGPT and Codex starting in December.

The help article, updated on November 2, does not give the exact switchover date in December. Instant chats will not count against the shared allowance. Users can track remaining usage and reset times under Settings, Usage. Limits may apply over five-hour and weekly windows. Work and Codex already share the allowance included with each plan; the December change extends that pooling to ChatGPT itself.
