The change
On August 6, 2026, Google announced that Demis Hassabis is stepping back from day-to-day leadership of Google DeepMind. He becomes DeepMind chairman and Alphabet chief scientist. Koray Kavukcuoglu, formerly DeepMind CTO and Alphabet chief AI architect, takes over as senior vice president leading AI research and Gemini development, reporting to Sundar Pichai.
Context
Axios called it the biggest AI leadership shake-up since Sam Altman's brief 2023 ouster at OpenAI. The timing coincides with reported Gemini 3.5 Pro delays and senior researcher departures. Kavukcuoglu oversees Gemini, frontier research and the Gemini app and developer teams.
Why it matters
A frontier-lab CEO change often reshapes product priorities, release pace and regulator relations. For anyone watching Google in agents and models, the signal is: Hassabis stays on long-term vision; Gemini execution moves to Kavukcuoglu.
