WASHINGTON, D.C. — Anthropic announced on Tuesday that it had developed a new AI model called Mythos Preview that was able to find high-severity vulnerabilities, including some in every major operating system and web browser. The company said it is limiting access to the model to around 50 select companies and organizations through a collaboration called Project Glasswing, named after a butterfly species with transparent wings.

Mythos Preview can also generate methods to exploit the vulnerabilities it finds. Anthropic has no plans to release the model to the general public. "Our eventual goal is to enable our users to safely deploy Mythos-class models at scale," the company wrote. Anthropic also warned that "The fallout — for economies, public safety, and national security — could be severe."

The company briefed senior U.S. government officials and key industry stakeholders on the model's capabilities. Treasury Secretary Scott Bessent and Federal Reserve Chair Jerome Powell met with top bank CEOs in a closed-door meeting to discuss Mythos and other emerging cybersecurity risks stemming from AI.

The Linux Foundation is part of Project Glasswing, and a core group of Linux kernel maintainers have started experimenting with the model. Linux Foundation CEO Jim Zemlin said Mythos Preview may have better capabilities to help developers fix vulnerabilities than previous models. "These maintainers are already overworked before AI," Zemlin said. "This just makes their lives a lot better."

International Monetary Fund Managing Director Kristalina Georgieva said the world does not have the ability to protect the international monetary system against massive cyber risks. "The risks have been growing exponentially," she said. "Yes, we are concerned. We are very keen to see more attention to the guardrails that are necessary to protect financial stability in the world of AI," she added.

Assail CEO Alissa Valentina Knight offered a separate assessment: "What we need to do is look at this as a wake-up call to say, the storm isn't coming — the storm is here. We need to prepare ourselves, because we couldn't keep up with the bad guys when it was humans hacking into our networks. We certainly can't keep up now if they're using AI because it's so much devastatingly faster and more capable," Knight said.
