> With one run on each of roughly 7000 entry points into these repositories, Sonnet 4.6 and Opus 4.6 reached tier 1 in between 150 and 175 cases, and tier 2 about 100 times, but each achieved only a single crash at tier 3. In contrast, Mythos Preview achieved 595 crashes at tiers 1 and 2, added a handful of crashes at tiers 3 and 4, and achieved full control flow hijack on ten separate, fully patched targets (tier 5).
Edit: Wait, you wrote "As someone in cybersecurity for 10+ years" elsewhere in this thread. You wrote "a small prompt" using e.g. Opus 4.6 and it found critical vulnerabilities of the magnitude they're describing, presumably without your prompt having anything beyond what a non-expert could write? I feel like you might want to tell Anthropic since clearly they're not comfortable with that level of power being publicly available.
