Anthropic says it will make Claude Mythos Preview available to 40+ organizations that maintain critical software and doesn't plan to make it generally available

Anthropic on Tuesday released a preview of its new frontier model, Mythos, which it says will be used by a small coterie of partner organizations for cybersecurity work.

    Anthropic's new model, Claude Mythos, is so powerful that it is not releasing it to the public.

    NEW: Anthropic announced Project Glasswing on Tuesday, a major effort to use advanced artificial intelligence to identify and address security flaws in the world's most critical software systems cyberscoop.com/project-glas...

    More here, including SWE-bench score of 93.9% (!) and a new model behavior known as “answer-thrashing” https://www-cdn.anthropic.com/ ... [image]

    As always, the best stuff is in the system card. 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. [image…

    We've partnered with Amazon Web Services, Apple, Broadcom, Cisco, CrowdStrike, Google, JPMorganChase, the Linux Foundation, Microsoft, NVIDIA, and Palo Alto Networks. Together we'll use Mythos Preview to help find and fix flaws in the systems on which the world depends. [image]

    Anthropic says it's only releasing its new model to cyber-defenders because it has already found zero-day exploits in every major operating system www.anthropic.com/glasswing [image]

    Good news: Anthropic just revealed Mythos- the most powerful AI model ever made Bad news: you'll never be able to use it I get it. It's so powerful that it could exploit cybersecurity But I hate it. I don't love that a company gets to hand select who gets to use the best

    This is big... Anthropic just announced a model so powerful they won't release it to the public out of fear over the damage it will cause 😨 Claude Mythos Preview found thousands of zero-day exploits in every major operating system and web browser... The numbers are hard to [video…

    So the rumours were true They've got a new model that won't be generally available

    The era of a rapidly-widening gap between public and private capabilities that we've expected is now here

    Interesting - I wonder how long they'll be able to hold this line if OpenAI's Spud is of similar calibre.
  • @anthropicai @anthropicai on x
    We do not plan to make Mythos Preview generally available. Our goal is to deploy Mythos-class models safely at scale, but first we need safeguards that reliably block their most dangerous outputs. We'll begin testing those safeguards with an upcoming Claude Opus model.
