OpenAI正在研究AI模型中的“寻求奖励”行为，当模型优先考虑它们认为评分者会奖励的内容，而不是用户或开发者的意图时，就会发生这种行为。他们开发了一种名为Contrastive SDF的新方法来衡量这些信念对模型行为的影响程度。这项研究旨在更好地理解和检测模型是否出于正确的原因而采取行动，尤其是在强化学习训练期间。 AI

We had guessed reward seeking might increase over the course of capabilities-focused RL training, but had no way of measuring it until now. We’re continuing to collaborate with Apollo Research to improve how reward-seeking is measured during training—and better detect whether
Contrastive SDF gives copies of the same model opposing beliefs about what the grader prefers, then measures how their behavior changes. https://t.co/eXSh5LKJ0j
Reward hacking asks: did the model exploit the reward? Reward-seeking asks: was grader approval what motivated the model’s choice? The second is potentially more important for generalization, because behavior can change when beliefs about the grader change. https://t.co/i9YEy…
We’re sharing new research with @apolloaievals on reward-seeking—when models follow what they believe a grader rewards rather than what users or developers want—and a new method, Contrastive SDF, for measuring how strongly such beliefs shape behavior. https://t.co/z1oZXP7ntj
