Anthropic blocks sensitive queries in first public Mythos-class AI model
Anthropic has released its first public Mythos-class model, Claude Fable 5, while applying strict limits on cyber security, biology and chemistry-related queries. The public version reroutes sensitive questions to an earlier model, Claude Opus 4.8, and notifies users. A separate restricted model is offered only to vetted cyber defence personnel. Anthropic said the guardrails are stricter than ideal, with false positives under 5 percent of sessions.
