Anthropic 在 AI 蒸餾戰中將 Claude Token 盜竊率降低 99%
anthropic 通過新防禦措施降低了claude推理token盜竊率90-99%，影響了zhipu和moonshot等中國公司的工業規模蒸餾攻擊。
anthropic has successfully defended its claude models against industrial-scale distillation attacks, reducing the volume of extracted reasoning tokens by 90 to 99 percent. the attacks, carried out by networks of hundreds of thousands of fake accounts, were used by companies like zhipu and moonshot to copy claude's capabilities. zhipu allegedly used the stolen capabilities to train its glm-5.3 model, while moonshot secretly routed queries through claude. anthropic's new defenses include restricting access to claude's internal reasoning steps, running a classifier to detect extraction attempts, and automatically banning flagged accounts. tens of thousands of accounts have already been banned.
