ChatGPT web app discloses shared usage limit across ChatGPT and Codex from December

A hidden disclaimer in the ChatGPT web app's checkout says plan usage will have a shared limit across all of ChatGPT and Codex starting in December.

Tibor Blaho (@btibor91) posted a screenshot of the text on X on October 29, 2026.

The screenshot does not describe the size of the limit or how it is calculated, and no statement from OpenAI on the change has been reported. Andrew Curran (@AndrewCurran_) speculates that the change is part of a project to merge the Chat and Work tabs, and that the project will finish in November. Curran's account is a guess, not a confirmed plan.
