Sachin Katti, who joined OpenAI about a year ago to lead infrastructure, is stepping down. He announced the move on LinkedIn on Wednesday, saying he wants to "build something new." He will remain an advisor after his last day on Nov. 15.

OpenAI has named Uday Ruddarraju, currently CTO of compute, as Katti's replacement. Ruddarraju will lead the company's overall compute organization, according to a spokesperson. The change comes as OpenAI continues to scale its data-center and compute capacity.

Katti's departure is a notable shift in a key role, but his continued advisory role suggests a smooth handoff. The source does not indicate any reason beyond Katti's stated desire to build something new.
