## AI 摘要

Anthropic 宣布恢复对在 Claude 回应前被安全护栏拦截的请求计费，仅适用于生物、蒸馏攻击和前沿 LLM 开发等低误报类别，称近期遭遇协同攻击，此举是一层防御。近期测试中 99.7% 使用 Claude Code、Claude.ai 或 Cowork 的账户未触发这类计费拦截，分类器误报率调至低于 0.1%；误判可通过 Claude Code 的 /feedback 上报。

## 正文

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://platform.claude.com/docs/en/build-with-claude/refusals-and-fallback#how-refusals-are-billed
