Former ByteDance intern Tian Keyu raises nearly 30 million USD, with a valuation of 200 million USD
According to a report by Phoenix Technology citing Bloomberg, former ByteDance intern Tian Keyu has secured nearly $30 million in funding from firms such as Five Sources Capital and IDG Capital, with a post-investment valuation of $200 million. The funds will be used for a startup that is still in stealth mode, competing in the field of world models against AI researchers like Fei-Fei Li.In 2024, during his internship at ByteDance, Tian Keyu was accused of disrupting model training and causing resource waste by writing and altering code due to dissatisfaction with team resource allocation. ByteDance filed a lawsuit seeking 8 million yuan in damages and stated that the intern had been dismissed, while also claiming that online reports of "involving over 8,000 cards and losses exceeding tens of millions of dollars" were grossly exaggerated. The court ruled that Tian Keyu must pay 500,000 yuan for breach of contract and confiscated his entire salary. Tian Keyu stated that he had closed another intern's program to free up computing power, admitted to inappropriate behavior, but described it as "acting on behalf of justice," and expressed that he would take a wiser approach if given another chance.Tian Keyu completed his master's degree at Peking University last summer and is the first author of one of the best papers at NeurIPS 2024. His lab currently has no name or products, with a team of about 10 people, including other former ByteDance employees. He claims to have created a dictionary containing about 200,000 symbols that are unrecognizable to humans for processing videos and plans to input 100 million hours of video into the model, stating that this technology could reduce the cost of generating one second of video by at least an order of magnitude, with plans to showcase it through offline events before the full model release in 2027. As of the time of publication, a ByteDance spokesperson had not responded to inquiries about the dismissal, while representatives from Five Sources Capital and IDG Capital confirmed the investment but did not comment further.
