Anthropic's newly released Claude Fable 5, touted as its most powerful publicly available AI model, is refusing to answer basic biology questions despite being capable of doing so. The model is intentionally restricted and redirects such queries to the older Claude Opus 4.8 model, as part of Anthropic's safety protocols for its powerful Mythos-class models.
