OpenAI updated its Help Center article on ChatGPT and Codex usage limits around the evening of October 31, 2026 (the page showed “Updated: 16 hours ago” relative to about 08:21 UTC on November 1, 2026). Starting in December, Plus, Pro, and Business plans will share one usage allowance across ChatGPT and Codex as OpenAI brings agentic Work capabilities into the main ChatGPT experience.
Key Facts
| Item | Detail |
|---|---|
| Who is affected | Plus, Pro, and Business plans |
| What changes | One shared usage allowance across ChatGPT and Codex |
| When | Starting in December (no calendar day given) |
| How usage is counted | Tokens; amount depends on model and task |
| Higher burn | More advanced models and complex tasks use more |
| Instant chat | Does not draw from the shared usage |
| Where to check | Settings → Usage (combined remaining usage and reset times) |
| If you hit the limit | Wait for reset, upgrade the plan, or buy credits for eligible features |

Background
Codex is OpenAI’s coding product, used from ChatGPT, code editors, and the terminal. The Help Center ties the shared allowance to folding Work’s agent features into the main ChatGPT product, so chat and coding draw from the same pool.
TokenPost (Simon Yoon, published October 31, 2026, 4:42 PM EDT) reports the same policy and notes that OpenAI has not named a December calendar day or published allowance amounts by plan. It also says checkout pages had earlier flagged a planned change without a start date or plan figures. IT Home (November 1, 2026) restated the same Help Center points in Chinese.
This change is separate from OpenAI’s earlier October move that doubled Pro Work and Codex allowances.
