Google is adjusting its artificial intelligence leadership structure following a major announcement on Wednesday. Jeff Dean, a veteran chief scientist, departs the company after 27 years of service. He plans to launch a new venture named Discovery Loop, which is structured as a public benefit corporation focused on science and engineering.

Demis Hassabis, who founded DeepMind, transitions from his role as CEO of that unit to become its chairman. He also takes on the title of chief scientist for the parent company, Alphabet. Hassabis noted that he intends to step back from daily operational duties to focus on strategic, high-level objectives.

The search giant is also promoting Koray Kavukcuoglu to lead the AI division, where he will oversee the development of the next iteration of the company's AI models. This shift occurs as the organization faces significant pressure to remain competitive against other major players in the generative intelligence sector.

Alphabet shares saw a decline of approximately 4% following the news. The company continues to direct massive capital expenditure toward infrastructure and cloud capacity to support its internal and external workloads. These changes reflect an ongoing effort to prioritize AI development while managing high operational costs.
