Anthropic 将 Fable 5 生物误报减少 85% —— 但为何仍惧怕病毒学
anthropic 将 fable 5 的生物安全过滤器误报率降低了 85%，允许更多良性查询，同时封锁病毒学。科学家现在可以更好地使用医疗工具。
anthropic reduced fable 5's biology safety filter false positives by roughly 85%, ending the policy that rerouted nearly all biology queries to the less capable opus 5. the updated classifier permits benign tasks like interpreting lab results and understanding symptoms, but strictly blocks dual-use research in virology, toxicology, and molecular design. the company cites u.s. intelligence assessments and bioweapon studies as evidence that biological risks are harder to contain than cyber threats. access programs are being developed to allow researchers to eventually use these restricted features.
