US Accuses Chinese AI Firms of Industrial-Scale Model Theft
The United States is escalating its technological conflict with China by targeting Chinese AI companies DeepSeek, Moonshot AI, and Alibaba for allegedly using model distillation to systematically extract capabilities from American AI systems. US authorities, citing national security concerns, accuse these firms of bypassing access restrictions and using automated methods to harvest model outputs for training their own models. Anthropic reported identifying over 3.4 million suspicious interactions with its Claude models from Moonshot AI, while OpenAI flagged activities consistent with adversarial distillation attempts by DeepSeek. The dispute highlights the growing importance of model distillation as both a legitimate development tool and a point of contention, with potential implications for licensing, trade secrets, and access controls. The US government is treating advanced AI as dual-use technology, similar to chip export restrictions, which could lead to sanctions affecting cloud services, chips, and other components.
This is a major policy update from the US government targeting major AI companies, which could have significant implications for the AI industry and global technology trade.

U.S. may sanction China over AI model 'theft'
U.S. Treasury Secretary Scott Bessent said the United States will scrutinize Chinese open-source and open-weight AI models for signs of intellectual-property theft, noting U.S. model watermarks have been found on some Chinese systems and warning sanctions or other restrictions could follow. His remarks come as Chinese models — including Moonshot AI’s Kimi K3 — make rapid benchmark gains and threaten to undercut U.S. firms such as OpenAI and Anthropic. The inquiry follows allegations of large-scale distillation attacks (Anthropic has accused Alibaba), sits alongside tighter chip export controls and potential bans on overseas models, and will feed into planned U.S.-China AI talks in September.
US Agencies Accuse Chinese AI Companies of Copying US Models
The FBI, NSA, and CISA jointly issued advisory AA26-251A accusing six Chinese AI companies—DeepSeek, Moonshot AI, Alibaba, MiniMax, StepFun, and Z.ai—of systematically extracting capabilities from US frontier models such as Anthropic's Claude, OpenAI's GPT, Google's Gemini, and xAI's Grok. The alleged operations, ongoing since late 2024, involved mass-purchased fake accounts, API exploitation, and proxy services, with probable knowledge of the Chinese government. These actions reportedly reduced development costs and timelines for the Chinese firms. China denied the allegations as groundless, urging cooperation. The advisory recommends US companies boost security monitoring, restrict anomalous high-volume accounts, and even degrade answers for suspected attackers, a measure with potential collateral impact. This development intensifies US-China AI competition and raises concerns over model distillation.
Anthropic Accuses Chinese Firms of AI Distillation Attacks
Anthropic accused three Chinese AI companies—DeepSeek, Moonshot AI and MiniMax—of coordinated 'distillation attack' campaigns that extracted capabilities from its Claude model by flooding it with specially crafted prompts. Anthropic said the firms used commercial proxy services to bypass access restrictions and estimated more than 16 million exchanges with Claude from roughly 24,000 fraudulently created accounts; MiniMax accounted for over 13 million exchanges. The complaints follow similar allegations from OpenAI about DeepSeek. Both companies framed the activity as a national security and intellectual-property concern, and Reuters reported U.S. officials found evidence DeepSeek trained a model on Nvidia’s Blackwell chip. Industry experts noted distillation is a common technique but said the controversy centers on alleged fraudulent access and possible violations of terms of service.
