Anthropic Unveils Mythos Model for Cybersecurity via Project Glasswing

This is not a product launch. This is Anthropic building a moat out of trust. By restricting Mythos to a curated coalition of defensive partners, they are positioning themselves as the responsible steward of capabilities that are, by their own admission, too dangerous for open access. That is a fascinating competitive move — especially against OpenAI, which is busy acquiring media companies and publishing economic manifestos. The real story for builders: if an AI model can find thousands of zero-days in weeks, then every vibe-coded prototype sitting in production with unreviewed dependencies just became a much bigger liability. The gap between "it works" and "it is secure" is widening at exactly the moment more people are shipping AI-generated code without understanding what is inside it. Security scanning is no longer optional. It is table stakes.
