Key Gemini IMO Gold Contributor Nearly Became a Professional Pianist

帮Gemini拿下IMO金牌的关键先生，差点成了职业钢琴家

Yi Tay served as a modeling co-captain for Gemini Deep Think when it reached IMO gold-medal level, co-founded Reka AI in 2023, and returned to Google DeepMind after 639 days, while the article also notes his 2012 Trinity classical piano associate diploma.

Why it matters: HKR-H/K/R all pass, but this is a profile, not a Gemini capability launch. The concrete value is Yi Tay's role, Reka history, and 639-day return, so it sits in the 72–77 featured band.
