Is China replacing the U.S. as the world’s AI touchpoint thanks to Kimi K3?

The release of Kimi K3, an artificial intelligence model created by a former computer science graduate student at Carnegie Mellon University, has rocked parts of social media and the AI commentariat. The model, developed by Moonshot AI—a Chinese lab cofounded by that ex-student, Yang Zhilin—has wowed many observers with its capabilities. “Kimi K3 demonstrates the U.S. moat in building frontier AI software is not as durable as many of us had hoped,” says Ryan Fedasiuk, a fellow at the American Enterprise Institute. “We should expect Chinese AI labs to continue distilling and freely releasing a version of the American frontier at a pace just weeks behind U.S. labs.” Social media has been ablaze with eye-popping demonstrations of the model’s prowess, including its ability to spin up a convincing browser-based version of macOS in a matter of minutes. The demonstrations have led some observers to conclude that Chinese AI models have caught up with their U.S. counterparts. But Yang, and Moonshot itself, recognize what K3 is not. It is no Claude Fable or GPT-5.6 killer. The company’s CEO even added a line to the model’s release notes acknowledging a “noticeable gap” between K3 and the leading U.S. models. That gap, however, is closing. The U.K.’s AI Safety Institute published a report last week suggesting that open-weight models, such as those emerging from China, are now at most four to seven months behind the frontier, compared with a lag of six to 10 months throughout most of 2025. Nevertheless, the gap remains, and it was evident on the first day K3 became available to the public. “K3 is an extremely large and computationally demanding model. At nearly 3 trillion parameters, it requires nearly an entire server rack of high-end AI chips to run on,” says Fedasiuk. “Moonshot had serious issues with uptime on the day of K3’s release—the service was down and rendered errors for more than 60% of users who logged onto Kimi’s web portal—likely because Moonshot did not have sufficient access to compute.” Computing infrastructure is one area in which China and its leading AI companies may continue to lag behind the United States. “As models get even bigger and more performant, the real race is about building the computing infrastructure needed to run and serve AI to billions of weekly active users,” says Fedasiuk. It is notable that, during the same week Kimi struggled to meet its initial demand, OpenAI reset the rate limits for Codex and ChatGPT users twice, while Anthropic offered a reset of its own, even as both companies provided access to more powerful models. K3’s apparent success has prompted questions about whether Trump-era export controls designed to restrict China’s access to GPUs, the chips needed to train enormous AI models to a world-leading standard, have backfired by catalyzing Chinese AI development. Experts say they have not. “People often confuse there being some downsides of export controls, which export control hawks agree with, such as they encourage efficiency, with export controls being net harmful,” says Miles Brundage, an AI policy researcher. “There is every reason to think China would have stronger AI capabilities with no export controls and thus more compute,” he says. China’s success has come despite U.S. export controls, as well as comparatively weak enforcement in some areas. K3 does, however, demonstrate that it remains possible to approach the technological frontier outside U.S. control, which increasingly appears capricious. For countries worried that they could incur Donald Trump’s wrath and lose access to leading models such as Mythos and GPT-5.6, as has happened before (albeit temporarily), China may appear to offer a tempting alternative. Last week, China’s president, Xi Jinping, spoke at the World AI Conference in Beijing. As part of a four-point plan for the development of AI worldwide, Xi said that “we must uphold openness and win-win cooperation to drive innovative development.” Kyle Chan, a research fellow at the Brookings Institution, has compared the competition to the Apple-Android battles of previous generations. “The US is Apple and China is Android. That’s Beijing’s framing of the world,” he wrote on X . “The US offers a closed system where power and profits flow back to American corporations. China offers an open system where everyone, including the Global South, can participate and benefit.” How to read Xi Jinping’s speech at the World AI Conference: It’s not really about AI. It’s about seizing a moment of tech-driven transformation to push forward China’s foreign policy goals. The US is Apple and China is Android. That’s Beijing’s framing of the world.

China has benefited for years from the openness of U.S. AI research, an approach American companies are only now reconsidering as their models become more capable, potentially more dangerous, and riskier to release without restrictions. The rest of the world may not recognize that nuance or remember the history of American openness. It may instead see a United States increasingly determined to ration access to its most advanced technology, then look toward China, which is offering models that are nearly as capable, far cheaper, and accompanied by fewer apparent strings. K3 does not make Beijing the new center of the AI universe overnight. But it strengthens China’s gravitational pull in a way that DeepSeek ultimately did not .
