Yang Zhilin, a Key Figure in AI in China

The Chinese internet is currently captivated by Yang Zhilin, a visionary entrepreneur and founder of Moonshot AI. This 34-year-old is becoming a true sensation on Weibo, the Chinese social media platform, where he is often referred to as a "millennial genius." This sudden fame is primarily due to the impact of his latest artificial intelligence model, the Kimi K3, which has shaken the tech world.

A Model That Disrupts Tech Giants

Yang Zhilin has caught the attention of Weibo users with his Kimi K3 model, which has quickly gained popularity. The hashtag "The Tsinghua post-90s genius has caused American stocks to plummet" has become the third most searched topic in the technology category on Weibo. In China, the term "post-90s" refers to individuals born between 1990 and 1999. This hashtag was viewed 32 million times in just 24 hours, illustrating the extent of the interest generated by Yang and his work.

A Weibo user based in Beijing expressed admiration by stating, "We once chased after Silicon Valley's AI, but now a post-90s entrepreneur from Tsinghua has unveiled a cutting-edge open-source model, directly shaking Wall Street." This statement reflects the sense of national pride and technological emergence that Yang embodies.

The Impact of Tsinghua University

Yang Zhilin is often described as one of the top students from Tsinghua University, a prestigious institution in Beijing. Tsinghua is globally recognized for its data science and artificial intelligence programs, ranking among the top ten universities in this field according to the QS World University Rankings 2026. This reputation further enhances Yang's credibility as a leader in the tech sector.

Yang's Personal Appeal

In addition to his professional achievements, Yang Zhilin is also admired for his youthful appearance, earning him the nickname "baby face" among some Weibo users. However, others adopt a more pessimistic perspective, in line with the "lying flat" movement in China, expressing the sentiment that the future belongs to geniuses like Yang, leaving little room for ordinary individuals.

Moonshot AI and the Kimi K3 Model

Yang's popularity on Weibo coincides with the recent launch of the Kimi K3 model by Moonshot AI. This model promises to compete with those from Anthropic and OpenAI in areas such as coding, reasoning, and knowledge-based tasks. Moonshot AI announced that the model weights would be released on July 27, allowing developers to improve and adapt it to their needs.

The launch of the Kimi K3 had immediate repercussions on the stock market, triggering a massive sell-off of shares from major American tech companies like Google and Nvidia. This situation recalls the upheaval caused by DeepSeek, another Chinese AI startup, the previous year.

Industry Reactions

Moonshot AI had to temporarily suspend subscriptions due to the massive influx of new users, which strained its computing resources. Industry leaders have taken note of the impact of the Kimi K3. Guillermo Rauch, CEO of the cloud platform Vercel, praised the model by stating, "This is the first time an open-source model is ahead of all proprietary models for this comprehensive web engineering benchmark."

Elon Musk, CEO of SpaceX, also reacted by claiming that the upcoming Grok model could surpass the Kimi K3 due to its training on two trillion parameters. Yang responded on Weibo by welcoming Grok to the "2 trillion+ club," highlighting the fierce competition in the field of AI.
