Anthropic's Fable AI avoids basic biology questions

Anthropic's latest AI model, Claude Fable 5, despite being touted as highly capable, refuses to answer basic biology questions. The model, designed as a public-facing 'Mythos-class' system, instead redirects such queries to an older model, Claude Opus 4.8. This behavior is intentional, as Anthropic considers Fable too dangerous for public release due to its advanced cybersecurity capabilities. The company's decision to restrict Fable's responses, even on simple topics, highlights their stringent safety protocols and concerns about potential misuse of powerful AI.
