Noam Shazeer, one of Google’s best-known AI engineers and a vice president of engineering, is leaving the company for OpenAI, less than two years after Google paid an estimated $2.5 billion to $2.7 billion to bring him back with a 30-person research team and access to their technology. The move marks the second time the 50-year-old has left Google.
Shazeer first joined Google in 2000 and spent 17 years there. He helped write the 2017 research paper that helped trigger the modern AI boom and is credited with inventing the Transformer architecture, which became foundational to many AI systems. In 2021, he left Google and co-founded Character.AI, a popular but controversial chatbot startup.
At Google until Wednesday, he was co-lead of Gemini’s AI models and was seen as central to narrowing Google’s gap with OpenAI’s ChatGPT. He announced his departure on X, saying, “It was a difficult decision to move on. I am very proud of the amazing team at Google and everything we built together,” and said he was “excited” to join “the extraordinary team at OpenAI.” Google thanked him for his “significant contributions,” while OpenAI CEO Sam Altman said on X that Shazeer was “one of the people I most wanted to work with since OpenAI was founded.”
The article says Shazeer lives in Palo Alto, is married to Yael, a Google corporate development executive, and has three children. He is the grandson of Holocaust survivors who later moved to the United States after spending time in Israel. His father, Dov, was a math teacher who became an engineer, and his wife’s parents, Nachum and Hanna Shacham, moved from Israel to Silicon Valley long ago. Hanna, a Technion graduate, is described as one of Silicon Valley’s leading real estate agents. His sister, Shira, has rabbinic ordination from Hebrew College in Massachusetts.
Shazeer’s move is the latest in a broader talent war among AI giants, as Meta, Google, OpenAI and Anthropic offer huge pay packages to lure top researchers and engineers.
