OpenAI Names Uday Ruddarraju CTO of Compute

OpenAI has promoted Uday Ruddarraju to CTO of Compute. This places the former xAI infrastructure leader in charge of scaling systems for advanced artificial intelligence models. Ruddarraju joined OpenAI from xAI about a year ago. He now leads efforts to expand compute, networking, storage, and machine learning systems. This infrastructure supports the training of frontier models like GPT-5.6. His background includes work at Amazon Web Services, eBay, and Robinhood. He stated his team has brought capacity online quickly and reliably, while also handling deeper systems work. The goal is to build the world’s largest compute footprint, covering distributed systems, hardware, and data centers. This promotion is significant because his experience is now focused on OpenAI's drive to expand its compute capacity for new frontier models.
