Jeff Dean, Google's chief scientist, is leaving the company after 27 years to co-found Discovery Loop, a public benefit corporation focused on applying AI to science and engineering, the company said in posts and a Google memo. Google senior fellow Sanjay Ghemawat will join Dean at the new startup, and Google told CNBC it will take a stake and invest in the venture. The New York Times reported Discovery Loop's seed backers include Radical Ventures and Khosla Ventures among others. The departures coincide with an AI reshuffle at Google: Demis Hassabis moves from CEO of DeepMind to a chairman and chief scientist role for Alphabet, and Koray Kavukcuoglu was promoted to head Google's AI division and will lead development of Gemini 4. Sundar Pichai described Dean's exit as amicable and said Dean and Ghemawat will work to "accelerate discoveries" in machine learning, science and engineering. The changes come as Google reports heavy capital expenditures and rapid cloud revenue growth driven by AI infrastructure and demand for its tensor processing units.
