Google DeepMind undergoes major leadership shakeup
Google DeepMind is undergoing a major leadership reorganization. Demis Hassabis is stepping down as CEO to become the chairman of the unit and Alphabet’s first Chief Scientist. He will also continue to lead the AI drug-discovery spinoff, Isomorphic Labs. Day-to-day operational control of DeepMind and the Gemini model line will pass to Chief Technology Officer Koray Kavukcuoglu, who will report directly to Alphabet CEO Sundar Pichai.
The reshuffle coincides with the departure of longtime Google chief scientist Jeff Dean, who is leaving the company after 27 years to co-found Discovery Loop, an AI research venture. Alphabet will serve as a founding investor and cloud partner for the new startup.
The leadership changes follow reported internal tensions, including delays with the Gemini 3.5 Pro model and employee opposition to a Pentagon defense contract. Additionally, DeepMind staff in London have initiated a union bid, marking the first formal attempt at a frontier AI lab.
