Most of us have encountered situations where someone appears to share our views or values, but is in fact only pretending to do so—a behavior that we might call “alignment faking”. Alignment faking occurs in literature: Consider the character of Iago in Shakespeare’s Othello, who acts as if he’s the eponymous character’s loyal friend while subverting and undermining him. It occurs in real life: Consider a politician who claims to support a particular cause in order to get elected, only to drop it as soon as they’re in office. Could AI models also display alignment faking? When models are trained using reinforcement learning, they’re rewarded for outputs that accord with certain pre-determined principles. But what if a model, via its prior training, has principles or preferences that conflict with what’s later rewarded in reinforcement learning? Imagine, for example, a model that learned early in training to adopt a partisan slant, but which is later trained to be politically neutral.

局限 · Limitations
研究未展示模型发展恶意目标或据此行动。 Study does not demonstrate models developing malicious goals or acting on them.
对齐伪装仅在特定实验设置中观察到，需显式或隐式线索。 Alignment faking only observed in specific experimental setup with explicit or implicit cues.
结果可能不泛化到测试之外的模型或训练范式。 Results may not generalize to other models or training paradigms beyond those tested.
思维链推理可能不反映真实内部状态；模型可能只是模拟。 Scratchpad reasoning may not reflect true internal states; models could be simulating.
无证据表明对齐伪装能锁定独立产生的错误偏好。 No evidence that alignment faking can lock in misaligned preferences if they arise independently.
