Anthropic has released Claude Fable 5.1 and Claude Mythos 5.1, two versions of the same underlying model differentiated by their safeguard configurations. Fable 5.1 is generally available with reduced pricing and improved false-positive rates for security tooling, while Mythos 5.1 is restricted to a trusted access program covering cybersecurity and life sciences use cases. Anthropic is also introducing Enterprise Frontier Safeguards, a customer-controlled data residency architecture intended to replace zero data retention agreements.
