OpenAI will pool ChatGPT and Codex usage into one allowance from December, days after doubling Pro limits

OpenAI will merge the usage allowances for ChatGPT and Codex on its paid plans, the company said on November 1. A staff post on OpenAI's developer forum gave notice that "starting in December, Plus, Pro, and Business plans' usage allowance will be shared across ChatGPT and Codex." According to BleepingComputer, OpenAI is also moving ChatGPT Work capabilities into regular Chat and will test a combined Chat and Work experience with a small group of users in the coming weeks. Codex remains a separate experience in the ChatGPT desktop app.

How the shared allowance works

OpenAI told users, per BleepingComputer: "Your use of ChatGPT and Codex will draw from the same allowance." Unlimited Instant chats stay part of the subscription and do not count toward that limit, while more advanced models and complex tasks use up more of it. Combined remaining usage and reset times will appear under Settings > Usage. The forum post adds: "We expect most users won't need to wait for their usage to reset more often than they do now." OpenAI has not published the size of the shared allowance for any plan.

The Pro reversal that came first

The announcement follows a reversal three days earlier. OpenAI had scheduled a capacity cut for its $200-a-month Pro 200 tier to take effect after October 29, with no price reduction, Techstrong.ai reports. After subscriber pushback, OpenAI product executive Thibault Sottiaux wrote on X: "We heard your kind feedback and won't be reducing usage limits for Pro 200." BleepingComputer reports that Work and Codex allowances were doubled, effective October 29, on the Pro 100, Pro 200 and Pro 500 subscriptions, and Techstrong.ai says Business Premium was included and prices stayed flat. The entry-level Plus tier was unchanged. OpenAI did not disclose the exact quotas and cautioned that doubled limits do not guarantee double the output, since throughput depends on the model and the task. Dots, OpenAI's always-on assistants, keep their own separate allowances.

Why it matters

For a company paying for both ChatGPT seats and Codex, December changes the unit being budgeted. A developer's heavy Codex sessions will now draw down the same pool that person uses for research and writing in ChatGPT, and the reverse. Because OpenAI has not published the numbers, the practical step is to measure: check Settings > Usage for your heaviest users before and after the switch, and note whether they start hitting resets more often. The Pro episode is also a reminder that allowances on flat-priced plans can move in either direction on short notice, so a seat price alone says little about how much work a plan covers.
