Sources: Google AI researchers Jonas Adler and Alexander Pritzel, both viewed internally as key contributors to Gemini, are planning to leave for Anthropic
Bloomberg
Context & Ripple Effects
This follows the reported departure of John Jumper from Google’s AI coding effort, another loss described as straining Google’s ability to compete with Anthropic and OpenAI. Related coverage also says Google widened an AI coding strike team into midtraining after major executive departures.
The planned moves matter because Adler and Pritzel are described as key Gemini contributors, while Anthropic is simultaneously extending its reach through implementation and education initiatives.
First-order effects
Google risks losing two researchers with material Gemini context and continuity; Anthropic would add that experience to its own research organization.
The departures add immediate pressure to Google’s AI leadership and teams already reorganizing around coding and model-training work.
Second-order effects
Google may need to devote more management attention to retention, team continuity, and accelerating its expanded coding and midtraining effort rather than solely product execution.
Anthropic’s ability to recruit from a direct rival reinforces its position in the competition for frontier-model and AI-coding talent, raising the cost of retaining comparable specialists across the field.
Third-order effects
If repeated departures persist, the competitive gap may increasingly turn on the ability to assemble and retain tightly coordinated research teams, not just on access to compute or distribution.
The pattern points toward greater concentration of scarce AI research expertise among a small set of labs; whether that translates into durable product advantage depends on how effectively each lab converts talent into models and deployed systems.
The trend: This is another data point in an AI-lab talent consolidation cycle, where researcher mobility is reshaping the relative capacity of the leading model developers.
Summer 2025: Meta raids OpenAI Summer 2026: Anthropic raids Google Here's what's important to remember: AI researchers are motivated by a range of things that shift very quickly — working on what's perceived as best models, access to compute, then maybe money. I think a ton of t…
$GOOGL is reportedly losing two more key Gemini researchers to Anthropic. Jonas Adler and Alexander Pritzel are expected to join the Claude maker following other high-profile exits like John Jumper to Anthropic and Noam Shazeer to OpenAI. [image]
IF this is true, then one thing i notice with the big departures lately is that most of them are long time Londoners leaving GDM. This would also be consistent with laments I've heard about the center of gravity for pretraining slowly but surely shifting to MTV.
Bloomberg reported that two more Google AI employees are leaving Google for Anthropic, Jonas Adler and Alexander Pritzel. Not to mention these two individuals who recently left as well. Typically this is always a sign when a company is about to release a sub-par model. This ha…
