Summary

American AI researcher — who co-invented the Transformer architecture (Attention Is All You Need, 2017) — left Google, founded Character.AI, sold it back to Google — whose technical contributions to language modeling are more fundamental than almost any other individual.

Core Contribution

Co-creates the Transformer architecture — Shazeer is one of the eight authors of Attention Is All You Need (2017), the most cited AI paper in history, which introduced the architecture underlying every major LLM including GPT-4, Claude, and Gemini.

Key Spikes & Highlights

Was offered a $1M+ retention bonus to stay at Google in 2021 and declined it to found Character.AI — his willingness to leave a very senior position at Google at peak LLM relevance shows unusual confidence in his own ability to build independently
Character.AI was acquired by Google for $2.7B in 2024, with Shazeer returning to Google — the arc (left Google, founded company, returned to Google at vastly higher valuation) is the most successful Google spin-out and re-acquisition in the company's history
