[Anthropic Loosens Fable 5 Biological Restrictions, Everyday Health Questions Can Finally Be Answered Normally] According to monitoring by Beating, Anthropic has adjusted the biosafety restrictions of Claude Fable 5. Previously, when biological questions triggered the safety classifier, it would automatically switch to the less capable Opus 5. After the new classifier went live, biological-related fallback during testing decreased by approximately 85%. Ordinary questions such as lab result interpretation, symptom understanding, and biology learning are now more likely to be directly handled by Fable 5. [Original Link]
