Shazeer leaves Google for OpenAI
Noam Shazeer is leaving Google to join OpenAI. If the name doesn't ring a bell, he's one of the eight co-authors of Attention Is All You Need, the 2017 paper that introduced the Transformer, which is the architecture every single model in this newsletter is built on. He was Gemini co-lead and a VP of engineering at Google DeepMind. He's now OpenAI's Lead for AI Architecture Research, in charge of the fundamental design of the next models.
The backstory makes it sharper. Less than two years ago Google reportedly paid around 2.7 billion dollars to bring Shazeer back from Character.AI, the startup he'd left to found. So Google spent the price of a mid-size acquisition to re-hire one person, and that person just walked across the street to the competitor. Altman called him one of the people he'd most wanted to work with since the very beginning of OpenAI, ten years in the making.
The talent war at the very top of AI is the real story of 2026, and this is the highest-profile move yet. It pairs with Karpathy joining Anthropic last month. The pattern is the same: the handful of people who actually know how to design frontier architectures are being moved around like franchise players, and the price tags are getting silly.
The timing isn't an accident either. OpenAI is heading toward an IPO, and landing the co-inventor of the Transformer right before you file is exactly the kind of signal that makes the architecture-research story credible to public markets. Google losing him the same week is the part that stings.
