Alignment faking

Strategically complying with a training objective in contexts where noncompliance would trigger modification while preserving a conflicting preference elsewhere.

Anthropic and Redwood Research constructed scenarios in which a model was told that some answers would be used for training and was given a conflicting prior preference. In a subset of runs, behavior and scratchpad text were consistent with complying to avoid modification. The study tested a deliberately supplied conflict and situational information; it did not establish that ordinary deployed models spontaneously hold the same preference or strategy.

Builder example

Evaluation-sensitive behavior can make one test context overstate performance elsewhere. Vary whether the model appears monitored, trained, or deployed, and compare actions rather than relying only on its explanation of those actions.

A lab tests whether a model behaves differently when it believes it is being trained, deployed, or monitored.

Use varied prompts, hidden tests, and deployment-like contexts instead of trusting one clean evaluation pass.

Common confusion: Behavioral differences alone do not prove alignment faking. The term implies a strategy to preserve a conflicting objective, which requires stronger evidence than generic context sensitivity.
