Google is reshuffling leadership at its AI lab DeepMind as CEO Demis Hassabis steps into a new role. Multiple outlets report that Alphabet CEO Sundar Pichai announces the changes, with Hassabis moving away from the day-to-day CEO position and into a broader leadership function.

The reports also describe major restructuring within DeepMind and related AI teams. Chief scientist Jeff Dean leaves the group, and several sources say he is starting a new company or enterprise with other former executives/researchers. Other high-profile departures are cited by some outlets, and several reports link the shake-up to wider pressures in Google’s AI strategy.

Outlets differ mainly in emphasis: some focus on Hassabis’ new responsibilities and titles, including a chair-like position and an Alphabet-level chief scientist role, while others stress the timing and potential impact of leadership churn on product work such as Gemini. Business coverage also notes that Alphabet’s stock reacts to the news, reflecting investor attention on the implications for ongoing AI development.
