“Distillation,” or using the outputs of a smarter AI model to improve the performance of a weaker one, has become a point of controversy in the AI race. Chinese AI models trail America’s best by roughly seven months on key benchmarks. To catch up, Anthropic and others say Chinese labs are distilling their models—a violation of their terms. Anthropic published a report in February claiming other Chinese firms DeepSeek, Moonshot, and MiniMax generated 16 million exchanges with Claude through approximately 24,000 fraudulent accounts. In June, Anthropic reportedly sent a letter to U.S. officials accusing Alibaba of “brazenly” attempting to distill Claude’s capabilities. The hidden code that rattled Alibaba was built to help catch exactly this.
Anthropic frames distillation as a national-security threat, warning that foreign labs could funnel stripped-down capabilities into military and surveillance systems and let authoritarian governments “deploy frontier AI for offensive cyber operations, disinformation campaigns, and mass surveillance.” There’s a commercial angle too. If Chinese labs siphon American capabilities and release them open-source, they erode the very business model those labs are banking on.
