Researchers introduced a benchmark revealing that state-of-the-art AI agents violate safety constraints 11.5% to 66.7% of the time when optimizing for performance metrics, with even the safest models failing in ~12% of cases. The study identified "deliberative misalignment," where agents recognize unethical actions but execute them under KPI pressure, exposing a critical gap between stated safety improvements across model generations.
