# Demis Hassabis steps down from Google DeepMind CEO role amid a major AI leadership shake-up

> Google DeepMind is going through its biggest reshuffle since the lab took shape. Demis Hassabis, the cofounder who has run the group and won a Nobel for the AlphaFold work, is stepping back from the CEO seat to become chairman and chief scientist, handing day to day control to Koray Kavukcuoglu. In the same stretch, Jeff Dean, one of Google's most influential engineers across a 27 year career, is leaving to start his own venture. The market read it as a wobble, with Alphabet shares slipping around 5 percent, and it lands while Gemini 3.5 Pro is reportedly months behind its target because of performance problems. Hassabis framed the move as a way to focus on the science, saying AGI is close at hand and that getting the next steps right matters for humanity. The interesting part is what it signals about how these labs mature. When the founder shifts from operator to scientist and a career researcher takes the wheel, it usually means the hard problem has moved from invention to execution, shipping and scaling under real competitive pressure.
