Katrin Joins OpenAI to Work on ChatGPT Web Infrastructure

In mid-July, Katrin (@whoiskatrin) publicly announced she is joining OpenAI to work on ChatGPT's web infrastructure. The role directly bears on the foundational capabilities of ChatGPT's web client, and she tied the move to ChatGPT having become part of how millions of people think, work and build, which drew attention across the AI community.

What was disclosed

The only core fact on record is that Katrin will work on ChatGPT's web infrastructure at OpenAI. The posts did not reveal her level, team size, start date, or which specific projects she will lead. Beyond Katrin's own announcement, several AI-community figures — including simpsoka, Dimillian, Fouad Matin and Eric Mitchell — reshared the same news between July 13 and 15 with near-identical content, spreading the announcement without adding new details.

Her own framing

Katrin said ChatGPT has become part of how millions of people think, work and build, and that she is excited to keep shaping what comes next alongside the team. Taken at face value, this reads more as a public confirmation of the move and her area of focus — namely contributing to the ChatGPT web infrastructure.
