Anthropic Expands Glasswing as Claude Mythos Goes Wider

Anthropic is expanding access to its most advanced AI model, inviting around 150 more organizations from 15 countries into Project Glasswing. This initiative focuses on security and partners with the Claude Mythos model.

What Is Project Glasswing?

Project Glasswing is Anthropic’s controlled early-access program. It allows select organizations to utilize Claude Mythos, their top-tier AI model, to identify and address security vulnerabilities. You can think of it as a private beta, but instead of launching a new app, these participants are using AI to test the digital infrastructure that supports hospitals, water treatment facilities, and power grids.

The program started with a small group of partners. Now, Anthropic is scaling it up, aiming at organizations responsible for critical infrastructure. A successful cyberattack on these systems could impact over 100 million people, according to TechCrunch.

Who’s Getting Access?

The 150 new organizations span various sectors, including power, water, healthcare, and communications. Anthropic is focusing on industries where security failures can have dire physical consequences. A compromised water treatment facility or a hospital network disrupted by ransomware can result in loss of life, not just financial damage.

By spreading access across 15 countries, Anthropic is tackling this as a global infrastructure issue, not limited to the U.S.

The Public Model Promise

Along with the Glasswing expansion, Anthropic has pledged to release Mythos-class models to the public. This distinction is important. Right now, Mythos is available only to vetted partners addressing specific security challenges. A public release would extend that capability to developers, businesses, and researchers outside the program.

While Anthropic hasn’t set a specific release date for the public version, the commitment itself is significant. It positions Mythos as a near-term product rather than just a research experiment.

Why Critical Infrastructure?

Critical infrastructure is becoming a prime target for cyberattacks. Nation-state actors and ransomware groups increasingly target systems providing essential services. The stakes are much higher when a city risks losing access to water or power.

AI models like Mythos can potentially boost defenses significantly. Instead of a small team manually reviewing millions of lines of code, an AI can identify known vulnerability patterns at a scale and speed that’s unmatched. Imagine replacing a metal detector at an airport with a full-body scanner that can also detect new threats.

However, there’s a risk of misuse, which Anthropic is aware of through its controlled rollout. By keeping Glasswing access limited and partner-vetted, the company aims to ensure Mythos is used defensively before it becomes widely available.

What This Means for Everyday Users

Most people won’t interact with Project Glasswing directly. But if it performs as expected, they’ll notice the benefits. Improved AI-assisted security at power companies, hospitals, and water utilities could lead to fewer major outages and data breaches. For instance, the Colonial Pipeline ransomware attack in 2021 caused fuel shortages across the U.S. East Coast. Faster detection of vulnerabilities might help prevent similar incidents.

For those using Claude via Anthropic’s consumer products or the API, the public release of Mythos is particularly relevant. It would mark a significant upgrade over the currently available models.

Community Reactions

“The fact that they’re specifically going after water and power infrastructure is interesting. Most AI security plays are focused on enterprise software. This feels different.”

“150 organizations is still a pretty small beta for something this consequential. Curious how they’re vetting them and what happens when one of those partners has a breach.”

What To Watch

• Public Mythos release timeline: Anthropic has promised a public Mythos-class model but hasn’t confirmed a date. Keep an eye out for announcements in Q3 2026, given the pace of the Glasswing rollout.
• Glasswing results: The program’s credibility relies on whether partner organizations actually find and fix vulnerabilities. Anthropic will likely release case studies or security reports to show real-world impact.
• Competitor responses: OpenAI and Google DeepMind have their own ambitions in infrastructure security. An expanded Glasswing could push them to speed up their similar initiatives.
• Regulatory attention: Implementing advanced AI across critical infrastructure in 15 countries will attract scrutiny from regulators in the EU and U.S. Watch for any governmental reactions or framework proposals related to this expansion.
