Project Glasswing
An Anthropic-led coalition using frontier AI to find and fix critical software security flaws.
Definition
Project Glasswing is an Anthropic-led coalition, announced in 2026, that uses frontier AI for defensive cybersecurity — finding and patching vulnerabilities in critical software before attackers can exploit them. Its members include major technology, hardware, and security companies, and it runs on a restricted Claude Mythos model offered to organizations that protect critical infrastructure.
