AI developer Anthropic says its newest Claude artificial intelligence model is so good at finding cybersecurity vulnerabilities that it’s not releasable to the public. The company is instead providing the tool to big tech infrastructure providers so they can patch the flaws it finds.

In late March, word began to leak that Anthropic’s latest AI model, dubbed Claude Mythos (PDF), was going to be a leap forward for the company’s AI technology. Now, the company has previewed its capabilities and warned that Mythos represents a major cybersecurity threat, as its capabilities represent a leap forward in finding and exploiting online security vulnerabilities. 

“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 said in a blog post Tuesday. Anthropic said Mythos Preview, which has not been released to the public, has already found what it says are thousands of severe security vulnerabilities “in every major operating system and web browser.” Asked for comment, a representative for Anthropic directed CNET to the company’s blog post.

To address the cybersecurity risks, Anthropic said it’s launching a consortium called Project Glasswing that includes Apple, Amazon Web Services, Broadcom, Cisco, CrowdStrike, Google, JPMorgan Chase, the Linux Foundation, Microsoft, Nvidia and Palo Alto Networks. Anthropic said those organizations and more than 40 others will have access to Mythos in order to start the work of shoring up defenses against AI attacks and exploits. It’s committing $100 million in usage credits for Mythos and $4 million in donations to open-source security organizations. 

“The dangers of getting this wrong are obvious, but if we get it right, there is a real opportunity to create a fundamentally more secure internet and world than we had before the advent of AI-powered cyber capabilities,” Anthropic CEO Dario Amodei posted on X.
