Jumper, who served as a vice president at Google’s primary AI laboratory, gained international recognition alongside founder Demis Hassabis for pioneering AI models that predict complex protein structures. He confirmed his transition via a post on X, noting he will take a brief hiatus before joining the Anthropic team. This move follows the high-profile departure of Noam Shazeer, who left Google for OpenAI last week—a loss that underscored the aggressive talent war currently reshaping the industry. Alphabet shares responded to the broader market pressure and shifting personnel, sliding 5.9% to $345.71 by midday Monday.
