Two More Key AI Researchers Want to Leave Google for Anthropic — Bloomberg

Two leading Google researchers, who are considered key developers of the Gemini artificial intelligence model, plan to join Anthropic, the industry’s most valuable startup. Bloomberg reported this, citing sources.

Jonas Adler worked on AI-powered code-writing technologies at the company, while Alexander Pritzel was involved in training artificial intelligence systems, according to Bloomberg. Their departure could continue a string of significant losses for the search giant following the departure of Nobel laureate John Jumper (who is also joining Anthropic) and researcher Noam Shazir (who left for OpenAI).

Adler, Pritzel, Jumper, and Shazir did not respond to Bloomberg’s requests for comment. Anthropic declined to comment. A Google spokesperson said the company is confident in its position in the AI talent market and cited statements by Google DeepMind CEO Demis Hassabis. He said that Google has a “fair share of talent” and noted that the company has “the longest and broadest research pipeline of any lab.”

Alphabet’s personnel losses have alarmed investors: the shake-up is raising doubts about Google’s ability to compete in the fierce race to develop the best AI models, according to Bloomberg. Furthermore, this reflects the pressure that tech giants are facing from startups on the verge of an IPO. The opportunity to acquire an equity stake before the listing is attractive even to highly paid employees of IT giants, the agency reports.

Google's stock has fallen 11.5% over the past month, although it remains up 10.3% year-to-date and up 99% compared to the end of June 2025.
