Moonshot AI built Kimi K3 on 20,000 Nvidia chips from Alibaba

Chinese AI startup Moonshot has a computing power agreement with Alibaba ↗ 1.12% for the use of around 20,000 Nvidia ↗ 2.65% chips, Bloomberg reported on July 31, citing people with knowledge of the companies' operations. The hardware forms a substantial chunk of the overall computing capacity Moonshot uses for its Kimi models, underscoring China's continued dependence on Western semiconductors to power its AI ambitions.bloomberg

A Model That Shook the Market

Moonshot released Kimi K3 on July 16, a 2.8 trillion-parameter open-source model that rivals top systems from OpenAI and Anthropic on several benchmarks. Demand overwhelmed the company's servers within 48 hours, forcing it to pause new subscriptions. Semiconductor stocks sold off sharply in the aftermath, with the Philadelphia Semiconductor Index falling more than 20 percent from its June peak, according to Bloomberg.thestreet+2

The revelation of the Alibaba deal adds new detail to questions about how Chinese AI firms source the computing power needed to train frontier models. Alibaba, which has pledged more than $53 billion to AI and cloud infrastructure, is one of China's largest cloud providers and a major Moonshot backer.linkedin+1

Washington Turns Up the Pressure

The Bloomberg report lands amid escalating U.S. scrutiny of Moonshot's hardware access. On July 22, White House science and technology adviser Michael Kratsios accused Moonshot of conducting "large-scale, covert industrial distillation" of Anthropic's Fable model to build K3. He also alleged the company had acquired servers equipped with Nvidia GB300 Blackwell chips and was operating them in Thailand — hardware whose sale to Chinese firms is prohibited under U.S. export controls. Treasury Secretary Scott Bessent warned that "sanctions and Entity List designations will be on the table" if Chinese firms engage in IP theft.thinkchina+3

The accusations have drawn pushback. A Moonshot employee noted on X that Fable launched on July 1 and K3 on July 15, calling a two-week training timeline implausible. AI researchers have called the claims political, arguing that distillation alone cannot explain K3's capabilities.scmp

Broader Fallout Across China's AI Industry

The Moonshot controversy has become entangled with a separate leak involving DeepSeek founder Liang Wenfeng, whose transcript from a May investor meeting surfaced on Chinese social media on July 22. In it, Liang discussed DeepSeek's reliance on Nvidia chips and the computing power gap between China and the United States, stating that "four Huawei GPUs equal one Nvidia GPU, while still trailing by two years". The transcript was quickly censored on the Chinese internet amid fears it could aid U.S. enforcement of export controls.thinkchina

As AI becomes a flashpoint in U.S.-China competition, Meta ↘ 7.95% CEO Mark Zuckerberg pushed back against calls to ban Chinese models, telling the Financial Times on July 28 that restrictions would not be "an effective solution". More than 50 companies signed a letter on July 24 opposing open-weight AI bans, though neither OpenAI nor Anthropic joined.thestreet
