Project Glasswing brings together Amazon, Anthropic, Apple, Broadcom, Cisco, CrowdStrike, Google, JPMorganChase, Microsoft, NVIDIA, and Palo Alto Networks to defend the world's most important software using frontier AI capabilities.
The world's most important technology and financial institutions have joined together to secure the software that underpins modern society.
Frontier 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. Project Glasswing is an urgent attempt to put these capabilities to work for defensive purposes.
A general-purpose frontier model that reveals a stark reality: AI has reached a level where it can identify vulnerabilities that have survived decades of human review and millions of automated tests.
The same capabilities that make AI models dangerous in the wrong hands make them invaluable for finding and fixing flaws in important software before attackers can exploit them.
No single organization can solve these cybersecurity problems alone. Frontier AI developers, software companies, security researchers, and governments all have essential roles to play.
A structured framework that combines frontier AI capabilities with industry expertise to identify, fix, and prevent vulnerabilities at scale.
Claude Mythos Preview autonomously scans critical codebases to identify zero-day vulnerabilities across operating systems, browsers, and infrastructure software.
Every vulnerability is reported to the maintainer with a cryptographic hash for verification, and details are revealed only after a fix is in place.
Partners work together to patch vulnerabilities, share best practices, and develop automated defense systems that scale across the industry.
Anthropic commits to publishing public reports on lessons learned, vulnerabilities fixed, and practical recommendations for the evolving security landscape.
The powerful cyber capabilities of Claude Mythos Preview are a result of its strong agentic coding and reasoning skills, achieving the highest scores of any model yet developed across a variety of software tasks.
"AI capabilities have crossed a threshold that fundamentally changes the urgency required to protect critical infrastructure from cyber threats, and there is no going back. Our foundational work with these models has shown we can identify and fix security vulnerabilities across hardware and software at a pace and scale previously impossible."
"At AWS, we build defenses before threats emerge, from our custom silicon up through the technology stack. Security isn't a phase for us; it's continuous and embedded in everything we do. We've been testing Claude Mythos Preview in our own security operations, applying it to critical codebases, where it's already helping us strengthen our code."
"As we enter a phase where cybersecurity is no longer bound by purely human capacity, the opportunity to use AI responsibly to improve security and reduce risk at scale is unprecedented. Joining Project Glasswing allows us to identify and mitigate risk early and augment our security and development solutions."
"The window between a vulnerability being discovered and being exploited by an adversary has collapsed — what once took months now happens in minutes with AI. Claude Mythos Preview demonstrates what is now possible for defenders at scale, and adversaries will inevitably look to exploit the same capabilities."
"Open source maintainers — whose software underpins much of the world's critical infrastructure — have historically been left to figure out security on their own. By giving the maintainers of these critical open source codebases access to AI models that can proactively identify and fix vulnerabilities at scale, Project Glasswing offers a credible path to changing that equation."
"Promoting the cybersecurity and resiliency of the financial system is central to JPMorganChase's mission, and we believe the industry is strongest when leading institutions work together on shared challenges. Project Glasswing provides a unique, early stage opportunity to evaluate next-generation AI tools for defensive cybersecurity."
"Google is pleased to see this cross-industry cybersecurity initiative coming together and to make Mythos Preview available to participants via Vertex AI. We have long believed that AI poses new challenges and opens new opportunities in cyber defense, which is why we have built AI-powered tools to find and fix critical software flaws."
"Over the past few weeks, we have had access to the Claude Mythos Preview model, using it to identify complex vulnerabilities that prior-generation models missed entirely. This is not only a game changer for finding previously hidden vulnerabilities, but it also signals a dangerous shift where attackers can soon find even more zero-day vulnerabilities."
The fastest answers to the questions people ask first about Project Glasswing, Claude Mythos Preview, and how to participate.
The work of defending the world's cyber infrastructure might take years. For cyber defenders to come out ahead, we need to act now.
