Claude's Smallest Model Passes Rigorous Security Gauntlet Unscathed

Haiku 4.5's perfect score on adversarial security testing proves that Anthropic's safety architecture scales efficiently across model sizes—critical for cost-conscious enterprise deployments. This demonstrates organizations can adopt smaller, faster models without compromising security. However, the test used defensively-framed scenarios, leaving validation of real-world adversarial robustness for future testing rounds.
