“Baby-faced” billionaire Yang Zhilin recently dealt the biggest shock to Western markets since DeepSeek, wiping hundreds of billions of dollars off the valuations of AI and chip stocks.
Kimi K3, developed by Yang’s Moonshot AI, is the most advanced “open-weight” large language model to emerge from China yet, topping many benchmarks with its capabilities “at a third of the cost”.
At a stroke, notions of Silicon Valley’s technical dominance have been swept away, with its developer, Moonshot AI, challenging the likes of Anthropic and OpenAI at the frontier – prompting questions about their mega-valuations.

Moonshot’s founder has a good story to tell too, says The Telegraph. Yang Zhilin is a prog-rock devotee who named his firm in honour of Pink Floyd’s The Dark Side of the Moon, seemingly in tune with Western ideas and culture.
The 34-year-old has built a “mythology” that has “helped distinguish Moonshot from China’s otherwise austere AI industry”, says the Financial Times. Employees describe an intense culture of long hours in Moonshot’s headquarters in Beijing’s Haidian district. “But Yang has also infused the company with his own… obsession with rock music… A white piano stands prominently in the office.”
Yang Zhilin heads to China’s MIT
Yang Zhilin was born in 1992 and grew up in Shantou in the southern state of Guangdong – China’s industrial heartland. Former classmates recall that he was always “unusually gifted”. Having started coding in high school, he won first prize in the National Olympiad in Informatics, earning him direct admission to Tsinghua University, often dubbed “China’s MIT”.
Even in that specialised atmosphere, he was known as “Yang the genius” because of the way he managed to balance elite academic performance with his musical interests. He was a drummer in a campus band called Splay, organised music competitions and gained a reputation for being “romantic and idealistic”. Some reports suggest that he switched his undergraduate degree from thermal engineering to computer science, having been inspired by a Haruki Murakami novel.
In 2015, Yang Zhilin completed his PhD at Carnegie Mellon University, where he studied under AI gurus Ruslan Salakhutdinov and William Cohen, worked at Google Brain and Meta, and founded a retailer-focused start-up, Recurrent AI, before returning to China in 2019.
In 2023, he co-founded Moonshot AI with Tsinghua University classmates. “Recurrent AI taught him how to woo investors and scale a business,” says The Telegraph. “But he learned painful lessons too.” Moonshot’s early years, when he attempted to build a “Chinese-first version of ChatGPT”, were marred by a lawsuit from investors in Recurrent AI that saw him hauled before the Hong Kong International Arbitration Centre before a settlement was reached.
Moonshot’s chatbot Kimi was an instant hit, but also “plagued by outages and… overtaken by larger rivals”, says the FT. Rival DeepSeek’s successful R1 model was another “existential test”. Yang Zhilin returned to the laboratory to focus on model training. He also made the pivotal decision to make Moonshot’s AI models available to developers globally.
Moonshot’s open approach has enabled China to “cast itself as a champion of low-cost, open-source AI”, says The New York Times. But that openness has raised concerns in Beijing about “the potential threats the technology might pose” to Communist Party rule. “[He] may be wise to moderate his views,” says The Telegraph. “Other tech billionaires in China have found… that the Party likes its economic champions on a short leash.”
