Claude Fable 5把生物安全误报砍了85%，日常健康问题能直接答了，但病毒学这类敏感领域还是交给Opus 5。
Anthropic更新了Claude Fable 5的生物安全防护机制，以减少误报。该更新使生物学相关的回退数量在多个产品面上减少约85%。Fable现在能处理更多日常健康和教育类问题。但对于病毒学、毒理学和分子设计等双用途请求，仍会回退到Opus 5。目前它还无法用于专业生物学研究和药物开发。

We’re updating Claude Fable 5’s biology safeguards to reduce false positives. In our testing, this update reduced biology-related fallbacks by about 85% across our product surfaces. Fable can now assist on a wider range of everyday health and educational questions. We believe the biggest positive impacts of AI will be in biology and medicine, and we’re committed to putting frontier intelligence safely into the hands of as many researchers as possible. Fable will continue to fallback to Opus 5 for requests we consider dual-use—including virology, toxicology, and molecular design—so it isn't yet usable for professional biology research and drug development. We're committed to closing that gap through trusted access pathways for frontier biology capabilities. anthropic.com/news/improving… 💬 293 🔄 141 ❤️ 1773 👀 129314 📊 411 ⚡
