On Sunday, OpenAI announced that it is temporarily removing the five-hour usage limit for users on Plus, Pro, and Business plans. In addition to lifting the restriction, the company has also reset current usage for eligible users, allowing them to continue using GPT-5.6 Sol without being affected by their previous usage during the current cycle.
"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."
Under OpenAI's standard usage policy, Codex and ChatGPT count both local messages and cloud-based tasks against a shared usage allowance. ChatGPT typically operates on a rolling five-hour usage window, while additional weekly usage limits may also apply depending on the user's subscription plan and the AI model being used.
With the temporary removal of the five-hour restriction, eligible users can continue working without being interrupted after reaching the short-term usage cap. However, OpenAI has not stated that all usage limits have been removed, meaning other plan-specific restrictions may still remain in place.
Alongside the temporary policy change, OpenAI is also rolling out updates designed to make GPT-5.6 Sol more efficient. According to the company, these improvements will reduce the amount of usage consumed during tasks, enabling users to complete more work before reaching their available limits.
"[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.
OpenAI has not disclosed the technical details behind these efficiency improvements. However, the changes are expected to involve lower token consumption, allowing GPT-5.6 Sol to process tasks more efficiently while using fewer resources.
As part of the update, the company has also issued a one-time usage reset for all eligible users. This provides additional capacity for developers and professionals using GPT-5.6 Sol for coding, automation, and agentic workflows. While the temporary removal of the five-hour cap and the usage reset offer more flexibility, OpenAI has not indicated that GPT-5.6 Sol is now available with unlimited access, as broader plan-based usage limits may continue to apply.
