Anthropic 称新防御将 Claude 推理 token 被提取量削减 90% 至 99%
Anthropic says it cut Claude reasoning token theft by up to 99% in fight against industrial-scale distillation
Anthropic 表示其新防御措施将 Claude 内部推理步骤被提取的 token 量削减了 90% 至 99%，以应对大规模蒸馏攻击。这类攻击中，企业用数十万个虚假账号组成的网络系统性复制模型能力，用于训练自家更小的模型。

Anthropic is battling large-scale distillation attacks on its Claude models. In these attacks, companies systematically copy an AI model's capabilities to train their own, smaller models. Anthropic says its new defenses have cut the volume of extracted reasoning tokens, the model's internal chain-of-thought steps, by 90 to 99 percent. Attackers use networks of hundreds of thousands of fake accounts to pull it off.
Anthropic names Chinese companies Zhipu and Moonshot as participants. Zhipu allegedly siphoned cyber capabilities from leading US models for its GLM-5.3 model, while Moonshot secretly routed queries through Claude. The stolen capabilities could end up in foreign military and surveillance systems.
Anthropic now restricts access to Claude's internal reasoning steps, runs a classifier that detects extraction attempts, and automatically bans flagged accounts. Tens of thousands have already been banned. Anthropic is calling on other AI developers to adopt similar protections, although the company admits that legitimate users are getting caught up in the process too.
