OpenAI ChatGPT and Codex token pool merger

The gist

Latest: OpenAI to Unify ChatGPT and Codex Under One Token Pool in December

The shift moves Plus, Pro, and Business users from per-model message caps to a unified token budget, meaning heavy use of one product will reduce availability in the other. Developers and general users on the same plans will draw from the same pool.

The full picture

OpenAI will consolidate ChatGPT and Codex onto a single shared token allowance for Plus, Pro, and Business plan subscribers starting in December. The change coincides with OpenAI integrating the agentic features of ChatGPT Work into the main ChatGPT product. Currently, ChatGPT chats run on a separate per-model message cap system while ChatGPT Work already shares Codex's token limits. After December, every request across both products will be priced by tokens rather than by per-model message counts. Instant chats will not count against the shared limit.
