The Tale of Two Claudes: Unpacking Fable 5 and Mythos 5

In this episode, we dive into Anthropic's dual-release of Claude Fable 5 and Mythos 5, two highly capable AI models built from the exact same architecture but designed for vastly different worlds. We explore how Fable 5 protects the general public with novel cyber and biological fallbacks, alongside invisible safeguards that quietly thwart competing frontier AI development. Finally, we unpack the raw, unrestricted power of Mythos 5, detailing its exclusive use by vetted cyberdefenders and researchers through Project Glasswing to secure critical infrastructure.   https://www.anthropic.com/news/claude-fable-5-mythos-5 System Card: https://www-cdn.anthropic.com/d00db56fa754a1b115b6dd7cb2e3c342ee809620.pdf   Sponsor: https://cisomarketplace.services/program https://cisomarketplace.services/ai-services https://cisomarketplace.services/engagements/claude-cybersecurity-consulting
