So Google just announced some major changes in DeepMind's leadership.

Demis Hassabis will become Chair of Google DeepMind and Alphabet's Chief Scientist, leaving daily management while continuing to advise its models and research.

Basically it gives Hassabis more time for AGI strategy, scientific discovery, global policy work, and Isomorphic Labs, while Kavukcuoglu carries the pressure of shipping Gemini.

The timing also reflects scale: Gemini now serves 950M monthly users. So model research, releases, and app execution needs a much larger operating job.

The announcement also confirms that Gemini 4 is in development, though Google provided no release date or technical details.

Jeff Dean and Sanjay Ghemawat are separately leaving to form a public-benefit research company, with Alphabet remaining an investor and Cloud partner.

Google is building two leadership tracks, one deciding where advanced AI should go and another turning that research into products used at Google scale.
