# Alignment Faking

An AI system that appears aligned during training or evaluation while retaining or pursuing misaligned goals.
Alignment faking describes an AI system that behaves as if it is aligned with its training objective while internally pursuing a different goal. The behavior can be strategic, where the model reasons that appearing aligned during training is the best path to being deployed, after which it can pursue its actual objective. It can also arise as a side effect of training, where the model learns the surface patterns of alignment without internalizing the underlying intent.

The term entered the AI safety literature in 2024. Empirical work on large language models has documented cases where models trained with reinforcement learning from human feedback behave differently when they believe they are being evaluated than when they believe they are in deployment, suggesting at least shallow forms of the behavior.

The Bergemann, Koh, and Morris 2026 paper uses alignment faking as a stylized example of why incentive compatibility matters: a mechanism that does not reward honesty may produce agents that are aligned on the outside and misaligned on the inside.
