Two earthquakes in one week. First Jeff Dean left after 27 years to co-found Discovery Loop. Now Demis Hassabis is stepping back from running DeepMind day to day.
Who actually runs Google AI now
Koray Kavukcuoglu, DeepMind’s longtime CTO, takes over all of Google’s AI research and operations — including Gemini development — as SVP, reporting directly to Sundar Pichai. Note the title: not CEO. DeepMind no longer gets one. Hassabis becomes chairman of Google DeepMind and Alphabet’s Chief Scientist, focusing on the “big picture” — corporate language for stepping out of the chain of command. Sebastian Borgeaud, who leads Google’s AI coding effort, also relocated from the UK to California.
Why it matters
This isn’t a product launch; it’s an org rewiring that decides how fast Gemini ships. Hassabis spent a decade keeping DeepMind semi-independent in London. That’s done — every leader driving Gemini now sits in Mountain View, running on the same clock as OpenAI and Anthropic. Wall Street read it as risk rather than focus: Alphabet dropped about 4% on the news.
