Two high-ranking artificial intelligence researchers at Alphabet Inc. are leaving the company to join rival startup Anthropic PBC, a report on Wednesday from Bloomberg News said, citing people familiar with the matter.
The researchers identified by the report are Jonas Adler and Alexander Pritzel. Within Google, both men were regarded as central architects behind the company’s Gemini model. Adler’s move removes a prominent leader from Google’s AI coding efforts, while Pritzel’s departure takes away a core specialist who contributed to the teams that train foundational systems, the report said.
The timing compounds pressure on Alphabet. Although Google was an early entrant in AI research, much of the recent generative AI cycle left the company responding to advances from competitors such as OpenAI and Anthropic. Only in recent months has Google begun to show renewed momentum through newer models and investments in custom silicon. Still, that momentum appears fragile in light of the latest departures.
The report notes this defection follows other notable losses at Google in recent days, including Nobel laureate John Jumper’s move to Anthropic and prominent researcher Noam Shazeer’s decision to join OpenAI. Together, these moves contribute to investor concern over whether Google can maintain its competitive footing in AI development.
Investors are increasingly asking whether Alphabet can hold the line in the battle for AI leadership as these personnel changes accumulate. The Bloomberg report attributed its information to people familiar with the matter who spoke on the condition of anonymity.
Context and immediate implications
- Adler and Pritzel were viewed internally as important contributors to Google’s Gemini effort.
- The departures come alongside recent high-profile exits by other leading researchers to rival AI firms.
- Google has recently advanced new models and custom silicon but faces questions about sustaining momentum amid talent losses.
