OpenAI is temporarily relaxing GPT-5.6 Sol usage limits after demand for the company’s most powerful model surged over the past 48 hours.
On Sunday, OpenAI confirmed that it is temporarily removing the five-hour usage restriction for Plus, Pro, and Business plans, while also resetting current usage for everyone.
“The last 48 hours of Codex and ChatGPT Work have been intense,” OpenAI product lead Tibo said in a post on X.
“[We’re] temporarily removing the 5 hour usage limit restriction for all Plus, Business and Pro plans.”
For those unaware, Codex and ChatGPT count local messages and cloud-based tasks against a shared usage limit. ChatGPT normally uses a rolling five-hour window, while weekly limits can also apply depending on the plan and model. With the shorter restriction removed, users are no longer forced to stop working simply because they have exhausted that five-hour window.
GPT-5.6 Sol to Become More Efficient
OpenAI is also making GPT-5.6 Sol more efficient, so it consumes less of a user’s available usage and can handle more work before hitting the limit.
“[We are] rolling out changes that will make GPT-5.6 Sol more efficient across the board and that will be reflected in less usage being used so that it can take you further,” Tibo said.
The exact mechanism behind the efficiency improvement is not detailed, but it likely stems from lower token consumption. In addition, OpenAI issued a one-time usage reset, giving users significantly more room to use its flagship model for coding and agentic work, though GPT-5.6 Sol does not become completely unlimited as a result.
