Anthropic's unreleased Claude Mythos Preview model, powering its Project Glasswing initiative, has identified over 10,000 software vulnerabilities in just one month. Partners like Cloudflare and Mozilla reported significant increases in bug discovery rates, with Cloudflare finding 2,000 bugs and Mozilla finding 271 in Firefox. Anthropic has not yet released Mythos to the public due to concerns about potential misuse and the lack of adequate safeguards, but plans to do so in the future.
