Overview
- OpenAI says the London group will own key work on model safety, reliability and performance evaluation.
- The office, now about 30 researchers, will grow substantially, with no headcount or investment figures disclosed.
- London teams will continue contributing to products including Codex and GPT-5.2.
- The expansion heightens competition for UK researchers with Google DeepMind’s roughly 2,000-person workforce, with OpenAI promising very competitive pay.
- UK ministers and London’s mayor welcomed the move as bolstering national AI leadership, as the country works to expand data center and power capacity for advanced compute.
