OpenAI's head of computing capacity Sachin Katti is leaving the company next month after about a year and is expected to stay on as an adviser

Context & Ripple Effects
Katti joined OpenAI from Intel in November 2025 to help guide infrastructure efforts, after leaving Intel's CTO and AI officer role. His departure ends a short tenure in a role central to OpenAI's industrial-compute planning.
The change follows a sequence of senior exits, including Chief Futurist Joshua Achiam's July departure, an ethics-lead exit in August, and the reported loss of the head of data centers. Katti has said he will remain an adviser, while OpenAI has appointed Uday Ruddarraju to lead its infrastructure and compute businesses.
First-order effects
- OpenAI's operational ownership of infrastructure and compute shifts to Uday Ruddarraju as Katti prepares to leave, with Katti retaining an advisory connection after November 15.
- Katti's departure removes a leader who publicly said his team had secured double-digit gigawatts of compute capacity across several projects.
Second-order effects
- The earlier departure of OpenAI's head of data centers means Ruddarraju's organization must absorb continuity across both capacity planning and data-center execution rather than relying on separate incumbent leaders.
- Keeping Katti as an adviser gives OpenAI a narrower continuity channel for the compute projects he helped guide, but day-to-day authority moves inside the new leadership structure.
Third-order effects
- A run of short senior tenures across infrastructure, data centers, safety, and strategy makes institutional handoffs a material execution issue for frontier labs building large physical-compute operations.
- If this staffing pattern persists, compute buildouts will depend less on individual dealmakers and more on durable operating teams able to carry procurement, site, and deployment knowledge through leadership changes.
The trend: Frontier AI labs are becoming compute-capacity operators whose ability to execute increasingly depends on organizational continuity around physical infrastructure.
