Trader sentiment for Codex usage limit resets in the week of October 12 reflects the ongoing 28-day OpenAI challenge, where Tibo (@thsottiaux) has committed to daily shipments of either model improvements or full global resets for paid Codex and ChatGPT Work accounts. The most recent global reset landed October 11, following clustered events on October 7–8 tied to feature drops and community polls, amid a historical median cadence of roughly 3–6 days. This irregular pattern—driven by bug fixes, context length expansions like the GPT-6.1 Sol update to 500K tokens, and user milestones—creates uncertainty between one or three resets, as announcements depend on internal progress rather than fixed schedules. Banked resets add flexibility but do not count toward global tallies. Traders weigh recent acceleration against the risk of quieter stretches.
