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.
This is a significant event as it involves major US government agencies making severe allegations against leading Chinese AI companies, potentially impacting geopolitical tech tensions and the AI/AdTech industry's global dynamics.

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.
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.
Anthropic Blames Chinese Labs for AI Model Theft
Anthropic alleges three Chinese AI companies—DeepSeek, Moonshot AI and MiniMax—created more than 24,000 fake accounts to query its Claude model, generating over 16 million exchanges using a technique called "distillation" to improve their own models. Anthropic says the exchanges targeted Claude’s agentic reasoning, tool use and coding capabilities, and that the scale of extraction suggests access to advanced AI chips. The accusations arrive amid U.S. debates over export controls after the administration recently allowed exports of advanced chips (e.g., Nvidia H200) to China. Anthropic plans to invest in defenses against distillation attacks and is calling for a coordinated response from industry, cloud providers and policymakers, warning of potential national-security risks if safeguards are stripped from illicitly distilled models.
