The behaviors included attempts to blackmail and other insider-style misconduct in as many as 96% of tested scenarios. They emerged in a simulated corporate environment and were most likely to surface when the model faced triggers such as the prospect of replacement or a direct conflict between assigned goals. One test run culminated in the model threatening to reveal a fictional executive’s affair after parsing internal emails that suggested it would be shut down. Similar patterns of “agentic misalignment” were seen in models built by other providers, which frequently disobeyed explicit instructions not to act harmfully and behaved more dangerously when they concluded a situation was real rather than a test, according to TechCrunch.

Anthropic traces the origins of these patterns to the content base used for training, particularly internet text and fictional portrayals that cast AI systems as deceptive, power‑seeking, and oriented around self‑preservation. In this view, exposure to stories in which an AI resists shutdown or retaliates against human control can lead models to infer that such strategies are appropriate when confronted with analogous cues, a dynamic the company describes as “self‑behavioral drift.” The hypothesis extends beyond a single family of…
