Anthropic has developed a new artificial intelligence model, Claude Mythos, that it says is too powerful to be released to the public.

Instead, the company says it will make the AI model available to the world’s largest technology companies to use in identifying security vulnerabilities in their software.

Project Glasswing, as it is called, is an initiative that brings together Amazon Web Services, Anthropic, Apple, Broadcom, Cisco, CrowdStrike, Google, JPMorganChase, the Linux Foundation, Microsoft, Nvidia and Palo Alto Networks in an effort to secure the world’s most critical software.

“We formed Project Glasswing because of capabilities we’ve observed in a new frontier model trained by Anthropic that we believe could reshape cybersecurity,” according to the Anthropic announcement,

“Claude Mythos Preview is a general-purpose, unreleased frontier model that reveals a stark fact: AI models have reached a level of coding capability where they can surpass all but the most skilled humans at finding and exploiting software vulnerabilities.”

The company says Mythos Preview has already found thousands of high-severity vulnerabilities, including some in every major operating system and web browser.

As part of Project Glasswing, the launch partners will use Mythos Preview as part of their defensive security work, anf Anthropic will share what is learnt so the whole industry can benefit.

Access to Claude Mythos has also been extended access to a group of more than 40 additional organisations that build or maintain critical software infrastructure so they can use the model to scan and secure both first-party and open-source systems.

Anthropic is committing up to $100-million in usage credits for Mythos Preview across these efforts, as well as $4-million in direct donations to open-source security organizations.

“Project Glasswing is a starting point,” Anthropic declares. “No one organization can solve these cybersecurity problems alone: frontier AI developers, other software companies, security researchers, open-source maintainers, and governments across the world all have essential roles to play.

?The work of defending the world’s cyber infrastructure might take years; frontier AI capabilities are likely to advance substantially over just the next few months. For cyber defenders to come out ahead, we need to act now.”
