OpenAI Appoints Former xAI Executive Uday Ruddarraju to Lead Infrastructure

OpenAI has announced a significant leadership transition within its core technical operations, appointing former xAI executive Uday Ruddarraju to head its infrastructure and computing power business. This move comes as the artificial intelligence leader intensifies its efforts to scale hardware capabilities and manage the vast computational resources required for next-generation large language models. As part of the restructuring, the previous head of infrastructure, Sachin Katti, will depart his current post in the coming weeks to serve as an advisor to the company.

Strategic Shifts in Computing Power Management

The leadership change marks a pivotal moment for OpenAI’s hardware strategy. Uday Ruddarraju, who joined the company in 2025 after a stint at Elon Musk’s xAI, had already been serving as the Chief Technology Officer of the computing power department since July of this year. His promotion centralizes control over the physical and virtual systems that power the GPT-4 and upcoming o1 model series.

Under the new structure, the following responsibilities have been clarified:

• Uday Ruddarraju will oversee the broader infrastructure and computing power business.
• Richard Ho, the current chip lead, will assume direct responsibility for GPT-Infra related workflows.
• Sachin Katti will facilitate the transition by moving into an advisory capacity.

Stability Amidst High-Level Personnel Turnover

This reshuffling follows a period of notable volatility within the teams responsible for data center procurement, financing, and construction. In recent months, several high-ranking officials involved in the ambitious Stargate project—a rumored $100 billion supercomputer initiative in partnership with Microsoft—have resigned. These departures have raised questions regarding the long-term execution of OpenAI's massive infrastructure roadmap. The Stargate project is considered a cornerstone of OpenAI's plan to achieve Artificial General Intelligence (AGI) through unprecedented scaling of GPU clusters.

According to reports from Bloomberg, the recent changes reflect an ongoing effort to stabilize the teams tasked with securing the immense financial and physical resources required for future AI development.

By integrating Ruddarraju’s expertise from xAI, OpenAI appears to be prioritizing veteran leadership to navigate the competitive landscape of AI chips and cloud computing. The reorganization is expected to streamline the development of custom hardware and enhance the efficiency of the Azure-based clusters that remain critical to the company’s operations. This internal alignment is vital as the firm continues to compete with rivals like Google and Anthropic for dominance in the high-stakes generative AI market.
