OpenAI Day 13 resets Codex and ChatGPT Work usage limits

3 Key Points

  1. What happened

    On Day 13 of OpenAI's 28-day shipping event, Tibo Sottiaux announced a usage-limit reset for Codex and ChatGPT Work, saying it would land by EOD PST and later posting 'Done' about five hours afterward.

  2. Why it matters

    The reset is applied automatically to eligible usage pools rather than issued as a savable ticket, so users who had burned through their quota may get capacity back without spending a saved reset, though OpenAI did not publish which plans or how much was refreshed.

Context & Analysis

Day 13 sits inside OpenAI's self-described "28 days of Shipping" cadence, in which the company commits to shipping an improvement or a full reset every day. The reset follows a pattern: Day 10 was also a reset with a completion report, while Day 11 addressed capacity errors and Day 12 improved cache efficiency between sub-agents. Counting Day 2, 6, 8, 10 and 13, this is the fifth mass reset of the run, with Day 3 instead distributing a banked reset users could save.

The mechanics matter more than the headline. According to OpenAI's Help Center, ChatGPT Work and Codex share a usage pool that is not a simple message count — it shifts with the model used, reasoning level, token volume, multi-step tasks, fast mode and cloud tool use. Some plans layer a five-hour window on top of a weekly cap, while the Pro $100, $200 and $500 tiers have no five-hour window at all. That is why OpenAI's brief post did not translate into a clean "everyone gets 100% back" promise, and why it cautions against reading "Global" as a blanket wipe of all ChatGPT features and API quotas.

A practical distinction runs through the whole episode: the announcement, the 'Done' post and the refresh visible in your own account are three separate things. Sottiaux's 'Done' arrived at 06:12 JST, well before the 16:00–17:00 JST window implied by the original EOD PST guidance, but the reply context could not be directly verified and independent trackers are what recorded it as Day 13's completion. Users with heavy Codex workloads are therefore advised to refresh Settings → Usage before starting the next task rather than assume the reset has reached their workspace.

FAQ
Does this reset add a savable reset ticket to my account?
No. OpenAI's Day 13 post did not announce new banked reset tickets; this was an automatic reset applied directly to the targeted usage pools. Banked resets from Day 3 are a separate mechanism you activate manually and that carry their own expiry dates.
Will Pro $100, $200 or $500 plans get their five-hour window back?
Those Pro tiers currently do not have a Work/Codex five-hour window, so there is nothing of that kind to restore. Check Settings → Usage to see the weekly or plan-based limits that actually apply to your account.
If I had unused quota left, does it stack to 200%?
OpenAI did not announce any stacking. A reset refreshes the targeted pool up to its plan ceiling rather than adding unused capacity on top, so a user near 95% will see far less change than one near 20%.
Does this also reset normal ChatGPT messages or OpenAI API credits?
There is no announcement of a reset for the regular Chat tab, API rate limits or purchased credits. The Day 13 post covered the Codex and ChatGPT Work usage pools, which the two products share.
