The Cyber Verification Program expands to three tiers
Vetted defenders get Opus 5.5, Sonnet 5.5 and Mythos 5.1 with fewer safeguards.
Anthropic combined two programs into an expanded Cyber Verification Program with three tiers, each with its own verification requirements and controls. All tiers include Claude Opus 5.5, Sonnet 5.5, Mythos 5.1 and future models. Reuters reports the move follows Project Glasswing uncovering more than 100,000 vulnerabilities this year.
