OpenAI announced that, beginning in December, a portion of the usage quota for ChatGPT Plus, Pro, and Business plans will be shared between ChatGPT and Codex, enabling Work agents to integrate into ChatGPT’s main interaction interface. User conversations, programming tasks, and agent operations will gradually be brought under unified quota management, measured in tokens; consumption depends on model type and task complexity, with more complex tasks consuming more; scenarios such as instant chat are also being closely monitored.
