OpenAI Compute Chief Sachin Katti Departs, Uday Ruddarraju Takes Over

KEY FACTS

Sachin Katti, OpenAI's head of infrastructure and compute, announced his resignation on X on October 14.
Uday Ruddarraju will fill Katti's vacancy; Ruddarraju was promoted to Chief Technology Officer of compute capacity this summer.
After leaving, Katti is expected to move into an advisory role and continue working with OpenAI.
Katti joined OpenAI in November 2025 from the CTO position at Intel, spending about one year at the company.
During his tenure, Katti led the Stargate data center program and struck compute partnerships with SoftBank, Oracle, and AWS.

PHYSIX OBSERVATION

Compute is OpenAI's most cash-hungry and most critical lifeline right now, and Katti exits just as Stargate partnerships are beginning to roll out, with his successor coming from an xAI background - a subtly telling signal. Combined with the recent exodus of multiple executives, OpenAI's management stability is being repeatedly scrutinized, and the execution continuity of its compute strategy deserves close attention.
