OpenAI will merge ChatGPT and Codex token allowances in December 2026. The change applies to Plus, Pro, and Business plans. Both products will draw from one shared credit pool. Plus and Business plans retain a 5-hour usage limit. Pro plans have no 5-hour limit but may still face weekly caps. The shared pool is measured in credits per million tokens. Codex usage will now reduce the same allowance used for ChatGPT. Teams heavy on coding may find general chat usage squeezed. Business customers gain simpler tracking and forecasting. Open questions remain on how weekly caps interact with the new pool.
