Starting in December, OpenAI's Plus, Pro and Business plans will share a single usage allowance across ChatGPT and Codex. The change appears in OpenAI's help page on ChatGPT and Codex usage limits, updated on October 31, 2026.
In practice, chats in ChatGPT and coding sessions with the Codex agent will draw on the same balance. Usage is measured in tokens, the units of information a model processes and generates, and more advanced models and more complex tasks consume more of the allowance. Instant chat stays outside the meter: according to OpenAI, it does not draw from usage.
Combined remaining usage and reset times appear in Settings, under Usage. When the limit is reached, a subscriber can wait for the reset, upgrade the plan, or buy credits to keep using eligible features.
What has not been disclosed yet
OpenAI has not published an exact day in December for the change or the allowance amounts per plan. It has also not detailed how each plan's current limits will convert to the new single balance. Until those figures are published, the only reliable planning reference is each subscriber's own measured consumption.
OpenAI says it expects most users will not need to wait for a reset more often than they do today. That is the company's forecast, not a guarantee, and it matters most for people who alternate between chat and long agent coding sessions, which tend to burn many tokens quickly.
Why the change is happening now
The unification follows the convergence of ChatGPT and Codex: OpenAI is bringing the agentic capabilities of ChatGPT Work into the main ChatGPT experience. With a single balance, an agent's work of researching, writing and running code competes with everyday questions, making usage planning more important for developers and teams.
The change comes shortly after another limits adjustment: on October 30, OpenAI doubled usage limits on Pro plans after user feedback. These are distinct measures: one increased the allowance, the other changes how it is counted across two products.
