Day 10 of OpenAI's 28-day improvement-or-reset sprint is another full reset. Tibo Sottiaux posted the reset on October 15 at 04:55 UTC, and community trackers list it as the Day 10 outcome for Codex and ChatGPT Work users.

It follows Day 9, which shipped desktop storage optimizations cutting on-disk state by about 60%, and Day 8, which was also a full reset on October 12. Trackers count the sprint so far as a mix of shipped improvements and resets, with Day 11 still pending at sweep time.

For users, the practical effect is the same as earlier resets: paid Codex and ChatGPT Work allowances are restored without waiting for the normal window.
