Fable won’t answer basic biology questions
Anthropic's newly released Claude Fable 5 model deliberately refuses to answer basic biology questions despite being marketed as highly capable in biology, instead routing queries to the older Claude Opus 4.8. The design choice reflects Anthropic's cautious approach to deploying a powerful Mythos-class model that was previously deemed too dangerous for public release due to its cybersecurity capabilities.
