- Anthropic's Mythos Preview model identified 271 security vulnerabilities in Firefox 150 by analyzing its unreleased source code.
- Firefox CTO Bobby Holley believes this gives defenders a decisive advantage in cybersecurity, stating "we've rounded the curve."
- The previous model, Opus 4.6, found only 22 vulnerabilities in Firefox 148, showing Mythos's significant improvement.
- Mythos reduced the need for costly, time-consuming human effort or automated fuzzing to find bugs.
