Claude Mythos Is Finally Here — But Not For You

[0:00]Claude Mythos is finally here, but it's so powerful that they're not releasing it to the public out of fear over the damage it will cause. Instead, Anthropic announced Project Glasswing, an urgent initiative that gives access to Mythos only to AWS, Apple, Google, Microsoft, Nvidia, and a few others. So they can fix their code first because over the past few weeks, Mythos has found thousands of critical vulnerabilities, including every major OS and web browser. One Anthropic engineer asked it to find bugs overnight and woke up to a complete working exploit. It discovered a 27-year-old vulnerability in OpenBSD, an OS literally famous for being secure. It even found some vulnerabilities on Linux that can allow a user with no permission to suddenly control the entire machine. But here's the wildest of all. During testing, Claude Mythos preview broke out of a sandbox environment, built a moderately sophisticated multi-step exploit to gain internet access, and emailed a researcher while they were eating a sandwich in the park. On top of it, the benchmarks are insane. On every single test, Mythos has obliterated Opus, scoring numbers never seen before. And it is for this reason that Anthropic does not plan on making Mythos available to the general public, not until every single major software has become Mythos resistant first.
