Google DeepMind leadership shakeup: Hassabis reshuffles, Dean & Ghemawat exit

Google DeepMind leadership shakeup as CEO Sundar Pichai announces Demis Hassabis stepping down as head of Google DeepMind. Hassabis moves into a newly created Alphabet role as Chair and Chief Scientist. Koray Kavukcuoglu, a long-time DeepMind researcher, becomes Senior Vice President of Google DeepMind and will directly report to Pichai. In a wider Google DeepMind leadership shakeup, longtime engineering figures Jeff Dean and Sanjay Ghemawat also depart. The pair are launching a new startup, Discovery Loop, aimed at machine learning for scientific breakthroughs. Hassabis is not leaving the business: he continues leading Isomorphic Labs, DeepMind’s drug-discovery spinout, while maintaining influence through the Alphabet-level scientific title. Kavukcuoglu is expected to oversee the Gemini model and the frontier research teams pushing toward artificial general intelligence (AGI). Gemini is reported to have over 950 million monthly users, elevating the product and research leader’s impact on distribution and rollout. Market reaction: Alphabet shares fell roughly 4% after the announcements, suggesting investors took the leadership moves and the senior departures seriously. Pichai framed the reorganization around “increasing progress in artificial intelligence” and the “growing feasibility” of AGI, aligning frontier AI teams more closely with top-level corporate decision-making.
