Two key AI researchers at Google, a subsidiary of Alphabet, are reportedly planning to join rival Anthropic PBC, according to informed sources. Jonas Adler and Alexander Pritzel, regarded as key contributors to Google’s Gemini large language model, are set to join Anthropic; Adler previously participated in Google’s AI programming initiatives, while Pritzel was involved in AI system training. This follows a recent wave of senior talent departures, including Nobel laureate John Jumper joining Anthropic and star researcher Noam Shazeer moving to OpenAI. These departures have unsettled investors and reignited market concerns about Google’s ability to remain competitive in the AI race. Two informed sources revealed that shortly before Shazeer announced his move to OpenAI, computing resources allocated to a project he led were reassigned to Google DeepMind’s team in London to enhance cross-team collaboration and optimize work during the pre-training phase. Adler, Pritzel, Jumper, and Shazeer did not respond to requests for comment; Anthropic declined to comment. A Google spokesperson stated the company remains confident in its competitive position, citing remarks by Google DeepMind CEO Demis Hassabis, who said, “There is significant talent movement among all leading labs, and we are attracting a substantial share of top-tier talent.” Two informed sources indicated that, prior to his departure, Shazeer had been actively involved in developing a new AI architecture based on Transformer technology.
