OpenAI is set to introduce a shared usage allowance for ChatGPT and Codex in December, according to reports published on 2 November 2026. The change is expected to apply to Plus, Pro and Business plans.
The reported policy would combine the usage limits for OpenAI's ChatGPT assistant and Codex coding tool. Instead of managing separate allowances, eligible subscribers would use a common pool across both products.
What the reported change means
The available reports do not provide the size of the shared allowance or explain how usage will be calculated. They also do not state whether the change will alter the price of any plan.
For users who move between ChatGPT and Codex, a combined limit could make the allowance easier to track. However, activity in one service could also affect the amount available for the other, depending on the final rules.
Reports from Unite.AI, XenoSpectrum and Pasquale Pillitteri all describe the December change as a merger of ChatGPT and Codex usage limits. The reports identify Plus, Pro and Business users as the groups affected.
Wider OpenAI usage controls
OpenAI's earlier research-listed updates include new usage analytics and updated spend controls for enterprises, published by OpenAI on 18 June 2026. That earlier item concerns enterprise controls, while the December development concerns shared usage limits for ChatGPT and Codex.
The supplied material does not establish whether the two developments are part of the same policy programme. It also does not confirm whether other plans or products will be included in the shared allowance.
The next important details will be OpenAI's final allowance figures, the precise start date in December and the rules governing how ChatGPT and Codex activity is counted. None of those details is provided in the available reporting.
Conclusion
OpenAI is reported to be combining ChatGPT and Codex usage allowances for Plus, Pro and Business users in December. The final allowance size, counting method and exact launch date remain unspecified in the available material.
