What Cat Wu posted
The full note (via the post’s long-form text) opens with: *Some news: I’m joining OpenAI to lead product management for Core Products!*
Cat wrote respect for OpenAI for showing that scaling works, for bringing AI to over a billion people, and for believing great products are core to the mission. The post names excitement to work with @thsottiaux, an “incredible PM team,” and everyone across OpenAI. On the product direction Cat named, the wording points at building agents that have a user’s and a team’s back, and that keep people in control, so more time remains for the people and work that matter. The close: *Lots to learn, and lots to build*—plus a request to keep feedback coming.
Those lines are Cat’s own public wording on X. DigIntoAI has not seen a separate OpenAI HR brief beyond what the post itself says.
Tibo’s welcome—and a short joke
At 08:29:41 Asia/Shanghai (2026-11-05T00:29:41Z), Tibo (@thsottiaux)—whose public bio lists Codex & ChatGPT at OpenAI—quoted Cat’s post and wrote: *Welcome Cat. Stoked to be building together soon.*
About half a minute later, at 08:30:09 Asia/Shanghai (2026-11-05T00:30:09Z), Tibo replied in the same thread with a one-word follow-up: CatGPT. That reply reads as a welcome joke in the thread—not a product name, feature launch, or model release.
