Anthropic 将对被拒绝请求恢复收费，防御蒸馏攻击
Anthropic 要对被拒请求收费了，专门针对搞蒸馏攻击和生物类敏感请求的人，做 API 的可以看看自己会不会被波及。
Anthropic 宣布恢复对被拒绝的请求收费，理由是防止蒸馏攻击。收费范围覆盖涉及生物学、蒸馏攻击和 LLM 开发相关的请求。
此前这类被安全策略拦截的请求不产生费用，攻击者可借此低成本大量探测模型输出用于蒸馏。
Anthropic will resume charging for rejected requests in order to protect from distillation attacks.
This applies to requests related to biology, distillation attacks and LLM development. https://t.co/pTaOW503KW
