is undergoing a major restructuring.
CEO Demis Hassabis is giving up the title to become chairman of the unit and chief scientist of Alphabet, the company said Wednesday, formalizing a shift away from day-to-day management and toward AGI (artificial general intelligence) strategy and scientific applications of AI.
Koray Kavukcuoglu, DeepMind’s chief technology officer and Alphabet’s chief AI architect, is taking over daily operations as senior vice president of Google DeepMind. He will report to CEO Sundar Pichai rather than holding a stand-alone CEO title and will oversee Gemini model development going forward.
Hassabis, who shared the 2024 Nobel Prize in chemistry for his AlphaFold work, wrote to staff that he believes AGI is close at hand and that getting the next steps right is critical for humanity. He added he’ll spend more time at Isomorphic Labs, Alphabet’s AI drug discovery unit, which he has called the top application of AI for improving human health.
Alphabet shares fell around 5% on the news.
The reshuffle lands alongside another departure: Jeff Dean, Google’s chief scientist and a 27-year veteran at the company, is leaving to cofound Discovery Loop, a public benefit corporation aimed at automating machine learning, science, and engineering research. He’s joined by former Googlers Sanjay Ghemawat, Oriol Vinyals, and Quoc Le.
Alphabet is a founding investor in the new company and will supply cloud compute.
The timing comes at a difficult time for Google. Gemini 3.5 Pro, the next flagship model, is months behind its original June launch target. The company has also suffered from a string of exits from Gemini’s leadership and research ranks, including losing Gemini co-lead Noam Shazeer to OpenAI and Nobel laureate John Jumper to Anthropic.
