Anthropic is giving some of the biggest firms in the world access to an unreleased frontier model as AI systems begin to outperform humans at finding software vulnerabilities.
Anthropic’s Project Glasswing is a new initiative that brings together Amazon Web Services, Apple, Broadcom, Cisco, CrowdStrike, Google, JPMorgan Chase, the Linux Foundation, Microsoft, Nvidia and Palo Alto Networks to secure critical software infrastructure.
The project centers on Claude Mythos Preview, a frontier model that Anthropic says has already demonstrated advanced offensive capabilities.
Anthropic says the model has already identified thousands of high-severity vulnerabilities across major systems. Nicholas Carlini, a research scientist at the firm, says Claude Mythos Preview has already spotted vulnerabilities across every major platform.
“For OpenBSD, we found a bug that’s been present for 27 years, where I can send a couple of pieces of data to any OpenBSD server and crash it.
On Linux, we found a number of vulnerabilities where, as a user with no permissions, I can elevate myself to the administrator by just running some binary on my machine.
For each of these bugs, we told the maintainers who actually run the software about them, and they went and fixed them and have deployed the patches so that anyone who runs this software is no longer vulnerable to these attacks.”
The company warns that such capabilities are likely to spread rapidly, potentially reaching actors outside controlled environments. Project Glasswing is designed to redirect those capabilities toward defense, with partners integrating the model into their security workflows.
Anthropic is committing up to $100 million in usage credits for the initiative, along with $4 million in direct funding for open-source security organizations.
Last week, leaked documents showed that Claude Mythos is Anthropic’s most powerful model to date, and it is limiting access only to cyberdefenders.
