Announcements Expanding Project Glasswing Jun 2, 2026 Project Glasswing is our collaborative effort to secure the world’s most important software. In early April, we announced that roughly 50 initial partners had access to Claude Mythos Preview, and since then, they’ve been deploying the model to scan their codebases for vulnerabilities. We recently described how these partners have so far found more than 10,000 high- or critical-severity security flaws. We’re now expanding Project Glasswing. Following several weeks of close collaboration with our Project Glasswing partners, the security industry, open-source software maintainers, and the US government, we’re extending the partnership to approximately 150 new organizations. Each one will need to meet our security requirements before they gain access. The organizations in this new group are based in more than 15 countries, and most provide critical infrastructure to many more. (In the future, we intend to expand our geographical reach much further.) The group covers several industries that weren’t well represented in our initial cohort, such as power, water, healthcare, communications, and hardware. And many of the new partners are vendors—companies or nonprofits that maintain codebases that are relied upon by lots of other organizations around the world, including governments. What each partner has in common is that a successful attack on their codebase could be catastrophic. For most partners, we estimate that a major attack could affect more than 100 million people, with important ramifications for both global and national security. This expansion is the next step toward our long-term goals: for AI to make all software more secure, and for us to help the industry adjust to how AI could change many of the core assumptions of cybersecurity. The role of Project Glasswing Project Glasswing and the capabilities of Claude Mythos Preview have sparked broad conversations—both within the software industry and with governments—about how AI is changing cybersecurity. These conversations have informed how we’ve expanded the program. They’ve also shaped our thinking about the very purpose of Project Glasswing. Cheap, fast AI models with powerful cyber capabilities are around the corner. We want Project Glasswing to spur institutions toward operating norms that reflect this reality. Mythos Preview continues a long-term trend that we’ve been warning about for some time: within 6 to 12 months, we expect that many other AI companies will have Mythos-class models, and they could release them without safeguards that prevent misuse. In that world, cyberattacks could occur much more often, and in much more unpredictable forms. It’s imperative that cyberdefenders adapt to maintain pace . We see our role as twofold. First, to help the software industry adapt by safely providing wide access to better models, tools, and common infrastructure. Second, to steadily shift the support we provide, from finding vulnerabilities to disclosing, fixing, and deploying patched software. We’ll now discuss each of these in turn. Supporting cyberdefenders So far, companies, nonprofits, maintainers, and researchers have acted quickly. Within the first weeks of Project Glasswing, each member began using Mythos Preview at large scale, sharing information and best practices with other partners, and working with third parties to triage the model’s findings. These organizations’ methods for adapting to new tools can, and should, be replicated widely across the millions of organizations and developers who are vulnerable to cyberattacks. To support this, we recently released Claude Security , a product that uses our latest public frontier models, like Claude Opus 4.8, to scan codebases and suggest patches. We're also releasing—on request, to trusted security teams— the tools we developed to help Project Glasswing’s partners find vulnerabilities more quickly. We intend to go much further: our longer-term aim is to supp
