OpenAI Announces Major Expansion of London Office

OpenAI has announced plans to turn its London office into its largest research hub outside of the United States.

The company—which established a UK office in 2023—says it will expand its London-based research team, scooping up talent emerging from leading British universities. It has not indicated how many researchers it will hire.

“The UK brings together world-class talent and leading scientific institutions and universities, making it an ideal place to deliver the important research which will ensure our AI is safe, useful, and benefits everyone,” said Mark Chen, chief research officer at OpenAI, in a statement.

The plans bring OpenAI into direct competition for top research talent with Google DeepMind, the AI lab run by British researcher Demis Hassabis, which is headquartered in London. DeepMind has long-running partnerships with Oxford University and the University of Cambridge, where it sponsors professorships, funds research, and works alongside researchers.

At the latest careers fair at Oxford University, the floor was packed with undergraduates looking for technical roles and recruiters hiring for AI-related positions. “The demand and supply is increasing on both sides, even within a year,” says Jonathan Black, director of the careers service at Oxford University. “To have something like this turn up is a really positive sign.”

OpenAI’s team in London will continue to contribute to products like Codex and GPT-5.2, the company says, but will now “own” certain aspects of model development relating to safety, reliability, and performance evaluation.

In a statement, the UK’s science and technology secretary, Liz Kendall, described the announcement as “a huge vote of confidence in the UK’s world-leading position at the cutting edge of AI research.”

The announcement coincides with a push in the UK to scale the nation’s data center and power infrastructure to meet the voracious demand for compute among AI companies, including OpenAI.
