In an unprecedented move that highlights the rapidly evolving landscape of AI capabilities, Anthropic has announced Project Glasswing?? sweeping cybersecurity initiative that pairs an unreleased frontier AI model with a coalition of twelve major technology and finance companies. The goal: find and patch software vulnerabilities across the world’s most critical infrastructure before adversaries can exploit them.
The Model That Shouldn’t Exist
At the center of Project Glasswing sits Claude Mythos Preview, a general-purpose frontier model that Anthropic says has already identified thousands of high-severity zero-day vulnerabilities in every major operating system and web browser. The company is not making the model generally available.
“We do not plan to make Claude Mythos Preview generally available due to its cybersecurity capabilities,” said Newton Cheng, Frontier Red Team Cyber Lead at Anthropic. “However, given the rate of AI progress, it will not be long before such capabilities proliferate, potentially beyond actors who are committed to deploying them safely. The fallout??or economies, public safety, and national security??ould be severe.”
A Coalition of Giants
The launch partners include Amazon Web Services, Apple, Broadcom, Cisco, CrowdStrike, Google, JPMorganChase, the Linux Foundation, Microsoft, Nvidia, and Palo Alto Networks. The coalition represents an extraordinary gathering of competitors united by a common threat assessment: AI-powered cyberattacks are about to become dramatically more common and more dangerous.
CrowdStrike’s CTO Elia Zaitsev framed the initiative in terms of collapsing timelines: “The window between a vulnerability being discovered and being exploited by an adversary has collapsed??hat once took months now happens in minutes with AI.”
The Vulnerabilities That Shocked Experts
The technical results reinforce the urgency of the initiative. According to Anthropic, Mythos Preview found a 27-year-old vulnerability in OpenBSD, a 16-year-old vulnerability in FFmpeg, and multiple Linux kernel vulnerabilities. All have been patched.
Million to Give Defenders a Head Start
Anthropic is committing up to million in usage credits for Claude Mythos Preview across the effort, along with million in direct donations to open-source security organizations.
The Race Against Time
Cheng was candid about the timeline. “Frontier AI capabilities are likely to advance substantially over just the next few months,” he told VentureBeat. Anthropic built a model that can autonomously crack open the most hardened operating systems on the planet??nd is now betting that sharing it with defenders will do more good than the inevitable moment when similar capabilities land in less careful hands.
