According to reports, Tian Yuandong, co-founder of Recursive and former director of Meta FAIR research, recalled that Wu Yuxin, co-founder of Moonshot AI, was once his intern in 2015. To persuade his superiors to hire Wu Yuxin, Tian spent an hour arguing on the rooftop of a Facebook office building, ultimately betting his own reputation on the decision.

Subsequently, Wu joined FAIR, where he co-developed Group Normalization with He Kaiming and created Detectron2. Today, he is involved in the development of Kimi’s foundational model at Moonshot AI. Tian also emphasized that in the era of large models, technical doers who personally inspect data, write code, and rapidly iterate through experiments are more critical than ever—even founders must be hands-on.
