Google chief scientist Jeff Dean is leaving after 27 years to launch Discovery Loop, an AI startup focused on automating scientific discovery. Three other Google veterans are reportedly joining Dean, while Alphabet will be a founding investor and Google Cloud partner for the venture. Demis Hassabis is moving from day-to-day leadership of Google DeepMind to become Alphabet chief scientist and chair of DeepMind, with Koray Kavukcuoglu taking responsibility for Gemini model development and frontier AI research.
