@thsottiaux is the X account of Thibault Sottiaux, "Tibo", whose commits under the GitHub account tibo-openai appear in OpenAI's openai/codex repository. Every account-wide Codex reset on this board was announced from this account: DidReset has recorded 63 announcements from it, the latest on Sep 12, 2026. Each row below links the original post; nothing on this page is inferred from screenshots or from an X bio.
Who is @thsottiaux?
Thibault Sottiaux posts on X as Tibo (@thsottiaux) [1]. The same name signs 89 commits (as of 2026-09-18) to OpenAI's openai/codex repository under the GitHub account tibo-openai, between 2025-04-16 and 2026-04-26 [2]. That repository record is why this page lists OpenAI as his employer. It lists no job title, because no OpenAI page we could check states one, and an X bio is not a source.
OpenAI's help center describes the mechanism his posts announce: "An automatic or global reset refreshes the eligible usage limits specified in the announcement." [3] The announcement itself is usually one short post, such as "All reset for everyone. Enjoy the week with Astra." on 2026-09-08 [5] or "Reset all propagated. Sweet dreams." on 2026-09-12 [4].
Why do posts from @thsottiaux count as reset signals?
DidReset records official, account-wide announcements only. A post from this account is classified by what it says: a reset applied to everyone becomes a Reset row, a banked reset hand-out becomes a Reset card row, a capacity change becomes a Boost, a promotion a Promo, and a heads-up about a coming reset a Tease. Replies, screenshots and other people's summaries are not recorded.
Every row keeps the URL of the original post, so the wording can be checked. The board and the estimate on the Codex page are computed from these rows; the estimate is a cadence figure, not a schedule Tibo has announced.

FAQ
Is @thsottiaux an official OpenAI account?
It is a personal account, not a company account. The name behind it, Thibault Sottiaux, signs commits in OpenAI's openai/codex repository under the GitHub account tibo-openai, and OpenAI's help center describes the global resets his posts announce. This page lists no job title because no OpenAI page we checked states one.
How many Codex resets has @thsottiaux announced?
DidReset has recorded 63 announcements from this account, 47 of them account-wide resets; the first recorded is from Sep 17, 2025 and the latest from Sep 12, 2026. The Codex page lists every one with a link to the original post.
Does a post from @thsottiaux reset my own 5-hour window?
Only if the post says so. OpenAI's help center says a global reset "refreshes the eligible usage limits specified in the announcement"; run /status in the Codex CLI or open Settings → Usage to see what changed for your account.
