When Caution Goes Too Far: Claude Fable Won't Answer Basic Biology

Anthropic's Claude Fable, marketed as the company's most powerful AI model with superior biology capabilities, deliberately refuses to answer basic biology questions due to intentionally restrictive safeguards designed to prevent bioweapon development. However, the model's overly conservative filters block even harmless educational queries like 'what is DNA' or 'how do mRNA vaccines work,' raising significant concerns about whether the safety measures are proportionate to actual risks. This exemplifies the ongoing industry debate over the appropriate balance between AI capability and security precautions.
