ANNOUNCED
OpenAI puts ChatGPT and Codex on one shared allowance from December — measured in tokens, with Instant chat exempt
2026-10-31
OpenAI will pool the usage allowance for ChatGPT and Codex on its Plus, Pro and Business plans starting in December, according to its help-centre article 'Understanding ChatGPT and Codex usage limits', updated on October 31. Chat and coding work will draw on a single token-measured budget instead of the separate limits users have today, so heavy Codex use will leave less room for advanced-model chat, and the other way round.
The change is tied to OpenAI folding the agentic capabilities of ChatGPT Work into the main ChatGPT experience. Usage will be measured in tokens, with more advanced models and more complex tasks consuming more of the allowance. Instant chat — the fast default model — will not draw from the shared allowance at all.
OpenAI has given no exact December start date and no allowance sizes per plan. Users who reach the shared limit will have three options: wait for the reset, upgrade their plan, or buy credits to keep using eligible features. OpenAI says it expects most users will not need to wait for resets more often than they do now — a claim subscribers who split their time between chat and Codex will be able to test once the combined balance appears in Settings under Usage.
On November 1, BleepingComputer reported further detail from an email OpenAI sent to subscribers: the combined Chat and Work experience will first be tested with a small group of users in the coming weeks before it expands, and Codex will remain a separate experience in the ChatGPT desktop app. The same report notes OpenAI has already doubled Work and Codex allowances for its Pro 100, Pro 200 and Pro 500 subscriptions, effective October 29.
