Demis Hassabis steps back from running DeepMind as Alphabet reorganizes AI
Alphabet shares fell 4% after the changes, as investors weighed whether the move fixes missed Gemini release deadlines.
Alphabet is reorganizing its AI leadership, with DeepMind co-founder Demis Hassabis stepping back from day-to-day operations and taking on roles including chairman of DeepMind and chief scientist at Alphabet, while Koray Kavukcuoglu becomes senior vice president for day-to-day operations reporting to CEO Sundar Pichai, according to Yahoo Finance.
The leadership shake-up follows setbacks in Gemini development, with Gemini 3.5 Pro having missed three release deadlines. The timing has prompted questions from investors about whether the restructuring is intended to address stalling progress or signals deeper disruption in Google’s AI execution, the outlet said.
Yahoo Finance also pointed to a separate personnel exodus, noting that longtime chief scientist Jeff Dean left along with three other senior researchers to launch a new startup called Discovery Loop. Alphabet shares reportedly dropped 4% on the news.
The article links the changes to broader debate inside the company, including reports of frustration from some employees over sustained 60-hour work weeks and fallout from a controversial Pentagon defense deal, which helped trigger resignations and sparked the first unionization drive at a frontier AI lab. More than 580 employees signed an open letter urging Pichai to reconsider the deal, the outlet reported.
