By now, you\u2019ve heard about the latest frontier AI models that are remarkably good at finding vulnerabilities in code and creating potential exploits. So good, in fact, that these models have been significantly limited from general use in an attempt to give defenders time to find and fix vulnerabilities before attackers find and exploit them.<\/p>\n

For context, on April 7, 2026, we began testing Anthropic\u2019s Claude Mythos model as a launch partner for Project Glasswing. Our conclusion was clear: The latest models are extraordinarily capable at finding vulnerabilities and changing them into critical exploit paths in near-real-time. In Defender’s Guide to the Frontier AI Impact on Cybersecurity, I shared our early findings and recommendations.<\/p>\n

Since then, we\u2019ve continued testing the latest frontier AI models, including Anthropic\u2019s Mythos and Claude Opus 4.7 and OpenAI\u2019s GPT-5.5-Cyber as part of the Trusted Access for Cyber program. The big question just a few weeks ago was: \u201cAre we overstating the model capabilities?\u201d With more testing, I can confidently say we weren\u2019t. In fact, these models are likely even better at finding vulnerabilities than we initially realized. Today, we\u2019re providing an update on our ongoing research, our learnings uncovered in the process, and the approach we\u2019re taking to protect our customers.<\/p>\n

Find and Fix Before Attackers Find and Exploit<\/h2>\n

Today, we released our May \u201cPatch Wednesday\u201d security advisories, our monthly cadence of transparent vulnerability disclosure and remediation. This is the first time where the majority of findings were the result of frontier AI models scanning our code.<\/p>\n
