With compelling technology from Mythos, other agencies might not be far behind. (Picture: Shutterstock)Sources in contact with Axios claim the National Security Agency, the premier digital spying agency, is widely using Anthropic’s Mythos
The model was deemed too dangerous to be released, but is available to about 40 select organizations through Project Glasswing, which uses its advanced cyber capabilities to scan for exploits and vulnerabilities — before the rest of the world catches up.
Project Glasswing pokes holes in almost any software, and if it isn’t used defensively now — attackers might soon. (Picture: Anthropic)Anthropic has been cooking up the Mythos model lately, that internal documents had put as «a sea-change in capabilities,» and was too dangerous to release publicly.
Instead, they are releasing Project Glasswing, having found it to be especially suited for «an effort to secure the world’s most critical software.» It won’t take long for others to catch up, Anthropic says, and this is «an urgent attempt to put these capabilities to work» defensively.
Launch partners include a who’s who of Silicon Valley giants, and Anthropic claims it has already found thousands of vulnerabilities across every major operating system and browser.
The Mythos Preview model scores 93.9% on SWE-bench Verified compared to Opus 4.6 with 80.8%, and on SWE-bench Pro it is 77.8% vs 53.4%.
Smaller actors maintaining critical software will enjoy $100 million in usage credit donations from Anthropic — but for others it will cost a whopping $25/125 per million input/output tokens.
