Fable won’t answer basic biology questions

Anthropic released Claude Fable 5 this week, its most powerful AI model made widely available, highlighting its advanced biology capabilities. However, the model has demonstrated an inability to answer fundamental biology questions typically expected of a high school student. Instead of providing answers, Claude Fable 5 redirects these queries to its predecessor, Claude 3.5 Sonnet. This behavior was observed by researchers who tested the model, noting that it would not engage with basic biological concepts. The decision to defer such questions suggests a potential limitation or a deliberate design choice in Claude Fable 5's knowledge base or reasoning pathways concerning foundational biological information. This contrasts with Anthropic's claims of enhanced biological understanding in the new model, raising questions about the practical application of its advanced AI in educational or general knowledge contexts.
