Day 9 of Tibo's ship-or-reset: Codex and ChatGPT desktop apps cut on-disk state by 60%
Day 9 of Tibo's 28-day ship-or-reset series. The ChatGPT and Codex desktop apps now use optimized on-disk state storage that cuts stored state by about 60%, answering complaints from power users running out of disk space.
What happened
On October 13, Thibault "Tibo" Sottiaux, OpenAI's Codex product lead, posted "Day 9/" in his 28-day ship-or-reset series: the team rolled out optimizations to how the ChatGPT and Codex desktop apps store state on disk, reducing the amount stored on disk by 60%. Tibo called it a "small ship" and said it responds to feedback from power users who were running out of disk space. Under his 28-day commitment, each day the team must either ship an improvement that clearly benefits most Codex and Work users or perform a full usage-quota reset; Day 9 was a ship, not a reset.
Why it matters
Codex and ChatGPT Work have grown to tens of millions of users, and heavy desktop users have reported disk space being eaten by agent state. A 60% cut in stored state directly lowers the footprint of long-running agent sessions on developers' machines, reducing friction for the power users most affected by quota and resource limits.
