US-China AI rivalry heats up as Chinese models gain ground

In what seems like the blink of an eye, China has gone from being up to five years behind the United States in top-tier artificial intelligence (AI) to lagging by just a few months.

While US players, including Anthropic's Claude and OpenAI's ChatGPT, have spent hundreds of billions of dollars to push the frontier of AI, China has pursued a very different path.

Faced with US curbs on high-end chips that help AI to do its most advanced thinking, Chinese tech firms have prioritized dozens of open-source AI models built on "good enough" technology.

These platforms, including DeepSeek, Alibaba's Qwen and Xiaomi's MiMo, are now widely deployed across Chinese businesses, government services and consumer devices.

In the latest sign of the gap closing, Chinese startup Moonshot AI last week unveiled Kimi K3, a model that rivals one of the most advanced AI models - Anthropic's Claude Fable 5 - on key benchmarks.

In some tests, Kimi K3 matches or even surpasses Claude with far less computing power and at a fraction of the cost.

Global technology specialist Alvin W. Graylin thinks Kimi K3's arrival turns high-end AI from an expensive luxury into something practical and affordable.

Kimi K3 "commoditizes frontier models," Graylin told DW. "For 98% of customers, the 1 to 2% difference [in knowledge] isn't worth paying 10 to 20 times more."

China's latest advance has already drawn a strong reaction from Washington, with US President Donald Trump now threatening to block US access to Chinese AI models.

Treasury Secretary Scott Bessent, meanwhile, warned earlier this week that the US could sanction Chinese models over alleged intellectual property (IP) theft.

Anthropic and OpenAI have accused Chinese labs of using their models to train their own systems, a process known as distilling.

While distilling is a common practice by AI labs worldwide to a limited extent, the companies say their models have been bombarded with queries to harvest advanced reasoning. The White House warned in April that China was doing it on an "industrial scale."

Beijing has hit back, rejecting the accusations as baseless and calling US threats of sanctions and model bans "technological bullying" to contain China's rise.

Giulia Neaher, a research analyst at the Strategic Foresight Hub at the Washington-based Stimson Center think tank, downplayed the role of distilling in Kimi's progress.

"A great degree [of its success] is due to the talent, infrastructure and the resources that were poured into building this model," Neaher told DW.

Neaher, whose research covers AI policy and governance, predicted a continued escalation in US antipathy toward China's AI advance as Washington reconsiders its "laissez-faire" approach to AI policy.

On the Chinese side, DeepSeek and Moonshot AI are also seeking to go public, with the latter planning a Hong Kong listing before early next year.

With China tech seemingly undervalued, US institutional investors have quietly increased allocations recently, betting they can sidestep a potential US AI bubble while positioning for China's momentum in what is fast becoming a neck-and-neck race.

"The long-term trend doesn't look good," argued Graylin. "There is a major US AI bubble and it's ripe for correction in the next three to 12 months." "The Chinese are building comparable models for 1/10th the cost and priced at 1/10 of US frontier."
