OpenAI Codex head Tibo clarifies that Pro plans have no 5-hour limit
OpenAI Codex head Tibo (@thsottiaux) posted on X on November 7, 2026 (Pacific Time) that, amid recent confusion, all Pro plans have no 5-hour usage limit. Compared with the Plus plan, the usage multiples for the various Pro tiers are as follows: Pro 100 is 10x, Pro 200 is 20x, and Pro 500 is 50x, and Pro 500 can use ultrafast mode.
This post was an explanation of the existing plan rules and did not announce any new quota adjustment or price change. Earlier, Tibo posted on October 29, 2026, saying that starting that day, usage limits for all Pro 100/200/500 tiers and Business Premium would be doubled, and explicitly that Pro 200’s Work and Codex usage would not be cut.

Tibo’s post directly addresses users’ questions about whether Pro plans have a rolling 5-hour window. He made clear that all Pro tiers (100/200/500 dollars) do not have this limit, and that usage is measured on a weekly basis in multiples relative to Plus. Pro 500 additionally gets access to ultrafast mode.
This follows on from the October 29 quota-doubling announcement: at the time, Tibo said limits for all Pro tiers and Business Premium would be doubled, and that the plan to reduce Pro 200 would be removed. The current multiples (10X/20X/50X) are consistent with the post-doubling status, with Plus still serving as the 1x baseline. The 5-hour limit had previously been re-enabled for Plus users to smooth compute load and prevent light users from exhausting weekly quota at once, but Pro users remained exempt.
For developers, the actual usable amount in the Pro plans depends on how the weekly quota is measured (messages, tokens, or equivalent API consumption), not just the multiple label. Ultrafast mode is available only on Pro 500 and may be billed or counted against quota at a higher consumption rate. Differences between the official help center pages and personal posts may still leave users needing further confirmation of the exact figures.
The observable change is whether later user reports show that the actual weekly consumption of each Pro tier matches the claimed multiples, and whether use of ultrafast mode significantly increases the rate at which Pro 500 quota is consumed. The indicators to watch are whether OpenAI’s help center updates the exact figures in sync, and community feedback on exhausting weekly quota under the no-5-hour-limit setup.

No 5-hour window limit on the Pro plan does not mean unlimited weekly usage; the multiples are the weekly usage ratio relative to Plus.
When a product lead clarifies the rules in a personal post, the specific numbers on the official help page may still lag behind the wording in the post.
Higher tiers (such as Pro 500) additionally provide ultrafast access, while also potentially consuming the same weekly quota pool at a faster rate.
