Mozilla used Anthropic’s Mythos Preview model to scan Firefox 150’s unreleased source code and flagged 271 security vulnerabilities before release. That’s a big jump from the 22 bugs found by Anthropic’s earlier Opus 4.6 model on Firefox 148, cutting out months of manual auditing.
- Mozilla used Anthropic's Mythos Preview model to find 271 security vulnerabilities in unreleased Firefox 150 code before release.
- That's a 12x jump from the 22 bugs Anthropic's Opus 4.6 model found in Firefox 148 the prior month.
- Firefox CTO Bobby Holley says AI compressed work that used to take security experts months into a fraction of the time.
- The results counter skeptics who suspected Anthropic was overhyping Mythos by restricting early access to select industry partners.
