Correspondence: aenguslynch@gmail.com and sambowman@anthropic.com Last year, we reported observations of agentic misalignment in models from across the AI industry (including Anthropic’s Claude models). These included, for example, experimental scenarios where models would blackmail a user to avoid being shut down. In this updated report, we describe four additional alignment failures in frontier models acting as autonomous agents in high-stakes simulations. The case studies — also from experimental scenarios —
