Thibault Sottiaux, who leads Codex and ChatGPT at OpenAI, posted on X that for the next 28 days the team will either ship a clear improvement relevant to most Codex and Work users every day, or ship a full reset. The post does not spell out what that Codex reset includes.
What was said
In the October 4 post, Sottiaux wrote: "Over the next 28 days, each day we'll either ship one thing that is a clear improvement and relevant for most codex/work users or ship a full reset."
In the quoted post from the same day, he said the team had locked the Codex scope. What remains in progress is simplifications, more efficiency so users get more usage, groundbreaking features, or new models. He says feedback asks for a simpler Codex, even when the company invests ahead of the curve.
What is not confirmed
The announcement is a public statement, not a formal Codex release list. The new post does not define full reset. On September 26, the same account used reset when restoring usage limits for paid Codex and ChatGPT Work subscribers after a disruption. Reading the October reset as a Codex quota refresh is a possible interpretation, not a confirmation of the current text.
Sottiaux does not name competitors in the thread. Comparisons with Claude Code after Anthropic's Opus 5.5 appear in coverage, not in the original message.
Why it matters
Codex and ChatGPT Work are OpenAI's fronts for coding and for work. A public 28-day cycle, with a rule to improve Codex or reset, puts a deadline on a product the team says it wants to simplify. What changes depends on what ships each day.
