Former ByteDance Intern Tian Keyu Raises Nearly $30 Million for World-Model Lab

Tian Keyu, a former ByteDance intern and NeurIPS Best Paper-winning researcher, has raised close to $30 million for an unnamed AI lab pursuing world models, valuing the venture at about $200 million after the investment. The financing, backed by investors including 5Y Capital and IDG Capital, puts a still-stealth project with no public name or product into one of AI's most contested new fields: systems that model how physical and virtual environments look, change and respond to actions, according to details of the financing.
