The Jagged Frontier: Small Models Challenge Mythos's AI Security Dominance

While Claude Mythos showcased impressive zero-day detection capabilities, smaller open-source models recovered much of the same analysis at a fraction of the cost, revealing that security expertise matters more than model size. The true competitive advantage in AI cybersecurity lies not in the model itself, but in the system architecture and deep security knowledge embedded within it. This discovery democratizes AI-driven vulnerability research and challenges the assumption that only frontier models can solve complex security tasks.
