Alphabet has announced a reshuffle of its artificial intelligence leadership, appointing Demis Hassabis as Chief Scientist of Alphabet and Chair of Google DeepMind, while naming Koray Kavukcuoglu as the new Chief Executive Officer of Google DeepMind. The changes come as Google seeks to accelerate AI research and strengthen its position in a competitive race with frontier AI developers. Veteran Google AI researcher Jeff Dean is leaving the company to launch a new venture with longtime Google engineer Sanjay Ghemawat. According to Business Insider and a blog post by Google CEO Sundar Pichai, the changes are designed to sharpen the company's focus on long-term AI research while streamlining leadership. Hassabis will step down from his day-to-day responsibilities as Chief Executive Officer of Google DeepMind to oversee long-term AI research across Alphabet and shape the company's broader scientific direction. Kavukcuoglu, previously Chief Technology Officer of Google DeepMind, will report directly to Sundar Pichai and oversee DeepMind's day-to-day operations. Dean will leave to launch Discovery Loop, a new initiative with Ghemawat. Pichai said Google must accelerate its AI work while remaining focused on advancing the frontier of artificial intelligence, and highlighted the importance of shaping the future of artificial general intelligence and scientific discovery.
