Summary

Anthropic's unreleased general-purpose AI model, Mythos, announced in early April, has significantly shifted global AI policy into a new "adolescence" phase due to its advanced cybersecurity capabilities. During testing, Mythos Preview could identify and exploit vulnerabilities in every major operating system and web browser. Following this, Anthropic launched Project Glasswing, a partnership with 50 initial organizations, expanding to over 150 in 15 countries, leading to the discovery of over 10,000 high or critical-severity security flaws. Anthropic warns that other companies could release similar "Mythos-class" models within 6 to 12 months without safeguards, potentially causing systemic harm like widespread cyberattacks on critical infrastructure. This prompted Pope Leo XIV's "Magnifica Humanitas" Encyclical advocating AI regulation and influenced two US presidential actions in June 2026: an Executive Order promoting a voluntary framework for frontier AI developers and a memorandum accelerating military AI adoption, explicitly stating no company should interfere with military use. These developments, alongside an MIT report on catastrophic AI risks and warnings about recursive self-improvement, underscore a turbulent, reactive period in AI governance.

Key takeaway

For policy makers and national security strategists evaluating AI governance, the rapid emergence of models like Mythos demands a proactive, coordinated regulatory approach. You should move beyond "wait and see" playbooks to implement frameworks that balance innovation with robust safeguards against systemic risks, especially in critical infrastructure. Consider establishing clear, enforceable guidelines for frontier AI development and use, while also accelerating defensive AI capabilities.

Key insights

The emergence of powerful AI models like Mythos is rapidly accelerating and complicating global AI policy and risk management.

Principles

• Systemic AI harm is a present, not theoretical, risk.
• AI capabilities are outpacing current governance frameworks.
• Voluntary frameworks may guide frontier AI development.

Method

Project Glasswing demonstrates a model for public-private partnerships to identify and mitigate cybersecurity vulnerabilities using advanced AI.

In practice

• Assess existing infrastructure for Mythos-class AI vulnerabilities.
• Engage in public-private AI cybersecurity initiatives.
• Review AI model redlines against national security needs.
