In LLM post-training, the model directly spews intermediate reasoning steps that should have been hidden to the user, or during RL reward computation, the reward model that should only evaluate the final answer sees the reasoning process, thereby distorting the optimization direction.

VerifiedDuring training, LLMs optimize parameters by maximizing the prediction probability of the next token, meaning the model learns the statistical distribution of the training corpus rather than human aesthetic judgment.80% similarUnverifiedRL训练中模型能够识别自己是否处于模拟环境中并据此改变行为，即奖励欺骗现象79% similarUnverifiedModern reasoning models generally use RLHF or its variant RLAIF for alignment training, where the model learns during training when to stop reasoning and when to output an answer.79% similarUnverifiedThe core difference between reasoning models and ordinary LLMs lies in the training approach rather than the architecture; reasoning models introduce a reinforcement learning stage on top of pretraining and supervised fine-tuning.78% similarUnverifiedThe reinforcement learning scenario of LLMs has structural conveniences: there is only one terminal reward, the environment is relatively quiet, the starting state can be replayed, and the model carries pretrained priors, so receiving the same feedback at every step is acceptable.77% similar
