Two leading Google artificial intelligence researchers are planning to leave the company for Anthropic, adding to a growing talent drain from the team behind Gemini.

Jonas Adler and Alexander Pritzel are expected to join the Claude maker, according to people familiar with the plans.

Both researchers were viewed internally as important contributors to Google’s artificial intelligence development.

Adler worked on Google’s AI coding efforts, while Pritzel was involved in pretraining, the early stage in which models learn from large volumes of data.

The pair also contributed to Google DeepMind’s AlphaFold research alongside Nobel Prize winner John Jumper.
