#OpenAI取消Codex5小时限制 OpenAI announced on July 13, 2026 that it is temporarily removing the 5-hour usage limit for Codex (and ChatGPT Work). The change mainly affects paid subscribers: Plus, Business, and Pro. The free tier is not included in this update. Note that the “5 hours” here does not mean you can only use it for 5 hours per day. Instead, it refers to a short usage window that resets every 5 hours, used to control high-frequency task consumption; after removal, that short-cycle quota ceiling will no longer interrupt long sessions or complex tasks. There are also two other changes:

OpenAI is optimizing the underlying model efficiency: tasks based on GPT‑5.6 Sol will reduce resource consumption, allowing the same quota to support longer conversations or more tasks.
Since the number of active users for the relevant products surpassed 6 million, the company carried out a one-time weekly quota reset about an hour after the announcement was published. But don’t take it as completely unlimited. The total weekly quota still applies: once you reach the maximum total quota within your plan, you may still need to buy additional credits to keep using it; the “fair use mechanism,” abuse-prevention rules, and other regulations also remain in place.
