the ex-intern just raised thirty million. tian keyu, fired and sued by bytedance for tampering with its model training, launched his own ai lab valued at 200 million dollars, per oct 10 reports.
the firing now reads as a credential.
Context
Bloomberg reported on Oct 7, 2026, and The Star on Oct 9, that former ByteDance intern Tian Keyu raised close to 30 million dollars from investors including 5Y Capital for a stealth world-models lab. Dealroom says the round values the 10-person company at 200 million dollars post-money.
Reuters reported in Nov 2024 that ByteDance sued a former intern for 8 million yuan, about 1.1 million dollars, alleging he deliberately attacked its model training infrastructure.
The roughly 30 million dollars and the 200 million dollar valuation match the sources, which say nearly 30 million. Reports are dated Oct 7 to 9, not Oct 10. The Reuters report of the ByteDance suit does not name him in the excerpt read, so the link between the suit and Tian rests on Dealroom's backstory line saying ByteDance dismissed him. 'Fired' matches that line; whether the firing is a credential is the author's view.
'the firing now reads as a credential' is the author's opinion.
