Anthropic 恢复对安全拦截请求收费
Anthropic 宣布对 Claude 安全防护拦截的请求恢复计费，仅限生物学、蒸馏攻击等低误报类别。
Today, we'll resume charging for requests our safeguards block before Claude responds. This only applies in categories with low false positive rates: biology, distillation attacks, and frontier LLM development. We've seen some coordinated attacks on our systems in recent weeks, and this is one layer of defense. In recent testing, 99.7% of accounts using Claude Code, Claude.ai, or Cowork did not hit any of these newly "billable blocks." The classifiers behind the blocks we’re resuming charging for today are tuned to have a <0.1% false positive rate. We know that's not 0%, and we're going to keep improving them so they interrupt your work less often. If you think a request has been blocked incorrectly, please report it with /feedback in Claude Code. https://t.co/uX6JhvN6He
