OpenAI is restructuring part of its compute organisation as three senior executives prepare to leave the company. Peter Hoeschele, who helped lead the early Stargate data center effort, has exited OpenAI. Meanwhile, Shamez Hemani and Anuj Saharan are also expected to depart soon.
Reports say all three executives are set to join the same startup. However, details about the new venture have not been disclosed. OpenAI has acknowledged the departures and, in parallel, pointed to an existing leadership change inside its industrial compute group.
OpenAI is also keeping Stargate UK on hold. As a result, attention is now on how the company is managing infrastructure planning while demand for AI compute capacity continues to rise.
Peter Hoeschele has left OpenAI, according to reports. He was one of the executives tied to the company’s early Stargate data center initiative. His work was linked to OpenAI’s effort to expand access to large-scale computing capacity.
Moreover, reports say Shamez Hemani and Anuj Saharan are expected to leave in the coming days. Both were part of OpenAI’s broader compute and strategy functions. Their departures come during a period of rapid expansion in AI infrastructure planning.
Reports also say the three executives are expected to join the same startup. Even so, OpenAI has not publicly named the company. In addition, no public description of the startup’s business has been released.
OpenAI said it appreciates the work done by the departing executives. An OpenAI spokesperson said, "We're grateful for the contributions Peter, Shamez, and Anuj have made to OpenAI and wish them the very best in what comes next." The statement sets out the company’s public response to the leadership changes.
At the same time, OpenAI pointed to the recent appointment of Sachin Katti to lead its industrial compute organization. His role places him at the center of OpenAI’s infrastructure planning as the company builds more capacity for training and deploying AI models. Accordingly, the appointment signals continuity inside a key part of the business.
Reports say OpenAI does not plan to directly replace Hoeschele’s role. Instead, responsibility for parts of his work may be distributed across the existing leadership structure. In turn, the move points to an internal reshuffle rather than a direct replacement.
Alongside the leadership shift, OpenAI has paused plans for Stargate UK, a proposed large data centre project in Britain. Earlier plans had presented the project as part of a wider effort to expand AI infrastructure across multiple regions. Britain had been part of those longer-term plans.
An OpenAI spokesperson said the company is waiting for the “right conditions” for a “long-term infrastructure investment.” The spokesperson also said, “We see huge potential for the UK’s AI future, and we support the government’s ambition to be an AI leader. We continue to explore Stargate UK.” So far, OpenAI has not said the project is cancelled.
Reports linked the pause to high energy costs and regulatory concerns in the UK. In addition, copyright rules tied to AI training have been part of the policy debate. OpenAI has not announced a new timeline for the next step on the project.
Stargate UK had been linked to data center builder Nscale and chipmaker NVIDIA. Earlier announcements described the project as an infrastructure platform designed to deploy OpenAI technology in the UK. The plan also included potential GPU capacity growth over time.
Reports said OpenAI had explored the offtake of up to 8,000 NVIDIA GPUs in the first quarter of 2026, with the possibility of scaling to 31,000 GPUs later. Cobalt Park was named as one possible site connected to the project. However, reports also said no confirmed construction progress had been announced for the location.
The UK plan was also tied to a memorandum of understanding signed in July 2025 between OpenAI and the British government. The agreement covered AI-driven growth, public sector use, and support for UK AI capability. Moreover, OpenAI described the commitments as non-binding, which meant no final investment obligation had been put in place.
