Hassabis steps back from running Google DeepMind — Kavukcuoglu takes the controls, reporting to Pichai

Sundar Pichai announced on 5 August 2026 that Demis Hassabis is stepping back from day-to-day leadership of Google DeepMind. Hassabis becomes Chair of Google DeepMind and takes a newly created role as Chief Scientist of Alphabet; he remains chief executive of Isomorphic Labs, the drug-discovery spin-off. Operational command passes to Koray Kavukcuoglu, who becomes Senior Vice President of Google DeepMind and reports directly to Pichai. His remit covers Gemini model development, frontier AI research and the Gemini app and developer teams. Kavukcuoglu is not an outside hire: he has been at DeepMind for thirteen years, started its deep learning team and led work behind WaveNet and DQN. The timing matters more than the titles. The reshuffle lands in the same week as the departure of Jeff Dean after 27 years at Google, together with Gemini co-lead Oriol Vinyals — a subject this catalogue covered separately. Within roughly a month Google has also shipped Gemini 3.6 Flash into general availability, put Gemini Omni Flash into public preview as its recommended video model, and released the Gemini Robotics ER 2 endpoints. A laboratory does not usually change its command structure in the middle of a release run unless the change is meant to separate two jobs that had grown too big for one person: setting the research direction, and shipping products on a quarterly clock. Hassabis has led DeepMind since he co-founded it in 2010, through AlphaGo, AlphaFold and the Nobel Prize in Chemistry that followed. Google's announcement gives no effective date for the transition. Reports of the market's reaction to the news come from press coverage rather than from the memo itself.
