Anthropic launches Claude Fable 5.1 and Mythos 5.1 with enhanced capabilities and tiered access
ByPulseAugur Editorial·[22 sources]·
Anthropic has released its latest flagship AI models, Claude Fable 5.1 and Claude Mythos 5.1. These models represent a significant advancement in capabilities, particularly for coding and knowledge work, with Fable 5.1 being generally available and Mythos 5.1 reserved for trusted access programs due to its more permissive safeguards for cybersecurity and life sciences. Both models share the same underlying architecture but differ in their safety features, with Mythos 5.1 offering a glimpse into AI's potential contributions to scientific progress. Anthropic has also focused on improving cost-efficiency, reducing cache read prices by up to 75% for agentic workloads, and enhancing enterprise-oriented controls like Enterprise Frontier Safeguards for improved privacy and observability.
