OpenAI has temporarily removed the five-hour usage interval limit for ChatGPT Work and Codex users on paid plans, according to a July 12 post by company executive Thibault Sottiaux on X.
The change applies to subscribers on Plus, Pro, and Business plans. It allows users to continue longer work sessions without being stopped by the previous five-hour interval cap. However, weekly usage limits are still in place, meaning access is not fully unlimited.
OpenAI has described the change as temporary. The company has not announced how long the relaxed limit will remain available or when the earlier restriction may return.
The change only removes the five-hour interval restriction for eligible paid users.
OpenAI’s own help pages state that Codex, ChatGPT Work, ChatGPT for Excel, and Workspace Agents draw from the same agentic usage and credit pool when these features are available on a user’s plan. This means users can still hit plan-based usage limits even without the five-hour cap.
OpenAI also says some Plus and Pro users can buy additional credits after reaching their limits, while others may need to upgrade or wait for their allowance to reset.
Morning. The last 48 hours of Codex and ChatGPT Work have been intense! Three important updates:
– Temporarily removing the 5 hour usage limit restriction for all Plus, Business and Pro plans
– Rolling out changes that will make GPT 5.6 Sol more efficient across the board and…— Tibo (@thsottiaux) July 12, 2026
Usage Quotas Reset
Sottiaux also said that usage quotas for ChatGPT Work and Codex had been reset.
He added that active users of the services had reached 6 million. OpenAI has not published a separate official blog post with further details about the reset or the temporary nature of the change.
GPT-5.6 Sol Improvements
OpenAI is also rolling out efficiency improvements for GPT-5.6 Sol, its high-performance model for coding, knowledge work, research, computer use, cybersecurity, science, and design.
The improvements are intended to reduce token consumption, allowing users to handle longer tasks and larger workloads within the same usage allocation.
OpenAI’s GPT-5.6 system card also says GPT-5.6 Sol showed better token efficiency than GPT-5.5 in certain tool-assisted vulnerability research tasks, including identifying useful leads and avoiding less promising paths.
Sottiaux said more detailed figures on the efficiency gains would be shared later.
