OpenAI Codex lead Tibo announces a Day 20 usage limit reset for Codex users, completing propagation ahead of midnight Pacific time
Day 20/ Rest and reset
Context
A global usage reset clears the five hour and weekly rate limit windows for paying Codex and ChatGPT users at once, giving developers a fresh quota heading into Sunday and the final week of OpenAI's 28 day October sprint.
Thibault Sottiaux, known as Tibo, leads Codex at OpenAI. On October 4 he committed to a 28 day daily series promising that each day the team would either ship a concrete improvement for Codex and ChatGPT Work users or trigger a global usage limit reset. Previous entries in the series included the Day 18 reset and Decisions API rollout on October 23 and the Day 19 cache preservation and CLI update later that evening.
Deep dive
At 11:39 PM Eastern on October 24, OpenAI Codex lead Thibault Sottiaux posted the Day 20 entry in his 28 day October series with the message Day 20/ Rest and reset. Rather than announcing a Saturday product feature, the team opted to give users a full usage limit reset under the rule Sottiaux set at the start of the month: every day without a substantive product improvement triggers a global quota reset. In a reply to developer Theo Browne later that night, Sottiaux joked that since the team did not ship a real improvement for the day, it was time to put the reset in the bag.
Thirty three seconds after the initial post, Sottiaux added a reply stating that the reset would finish rolling out by midnight Pacific time, which is 3:00 AM Eastern on October 25. At 2:06 AM Eastern, nearly an hour ahead of that target, he quoted his earlier reply to confirm that the reset had fully propagated across accounts, wishing developers happy coding for Sunday and teasing a fun week ahead.
A global reset clears active usage windows across Codex and ChatGPT plans simultaneously, though unlike a banked reset it takes effect immediately and cannot be saved for later. The third party tracker resets.pro logged the announcement at 03:39 UTC and marked the global reset live at 06:06 UTC upon Sottiaux's confirmation post, counting 16 days with product improvements and 10 days with usage resets so far in October.
What to expect next
With eight days remaining in OpenAI's 28 day October series, developers will watch what Sottiaux meant by teasing a fun week ahead after a quiet Saturday rest day. Users can verify their refreshed five hour and weekly usage windows in Codex Settings under Usage or by running the status command in the Codex CLI, and watch whether the final week brings larger feature launches or additional resets.
