Tian Keyu's lab raises $30M at a $200M valuation to build world models

On October 8, Bloomberg reported that Tian Keyu, a former ByteDance research intern and a PhD student at Peking University, has founded a stealth company betting on world models. The startup has raised close to $30 million at a post-money valuation of $200 million, and it has no name or product yet. The same report noted that Tian had been dismissed after entering ByteDance's training cluster and contaminating a colleague's model training, and that ByteDance sought RMB 8 million in damages, with a court ordering him to pay RMB 500,000.

On October 9, Leiphone reported that the lab has about 10 people and that Five Source Capital and IDG together provided the $30 million, valuing it at roughly $200 million. Leiphone also said the company has no product and no public name, and noted that Tian was involved in the ByteDance RMB 8 million claim while winning a NeurIPS 2024 Best Paper Award as first author. On the technical side, he argues that AI should invent its own language to understand the physical world, saying human language has too low an information dimension to fully describe physical reality, losing large amounts of physical information and wasting compute. That is the angle from which he is entering the world model race.

On October 10, OSChina repeated the Bloomberg report from October 8, citing the same figures: close to $30 million raised, a $200 million post-money valuation, and a company with no name or product. The two accounts agree on the funding amount, valuation, and the company's status, though they point to different disclosure dates, with Bloomberg on October 8 and Leiphone on October 9. They also differ in how they describe the ByteDance dispute: Leiphone frames it as a lawsuit seeking RMB 8 million, while OSChina says he was dismissed, faced the RMB 8 million claim, and was ordered by a court to pay RMB 500,000. Public information currently stops at the funding, with no name or product disclosed.
