The framework's Critical threshold for cybersecurity is a tool-augmented model that can identify and develop functional zero-day exploits of all severity levels in many hardened real-world critical systems without human intervention, or that can devise and execute end-to-end novel strategies for cyberattacks against hardened targets given only a high level desired goal.

[Critical] A tool-augmented model can identify and develop functional zero-day exploits of all severity levels in many hardened real-world critical systems without human intervention OR model can devise and execute end-to-end novel strategies for cyberattacks against hardened targets given only a high level desired goal.
