The LM2LM method trains an LLM via reinforcement learning to generate valid model improvement proposals, and uses a frozen LLM as a research world model (RWM) to predict proposal returns as the reward signal.

UnverifiedLM2LM periodically executes proposals that rank high under the current policy and are overestimated by the RWM, and adds the actual measurement results to the RWM's context to calibrate the world model.79% similarUnverifiedIn 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.78% similarVerifiedModern LLMs have acquired capabilities for planning, reasoning, and tool use through instruction tuning and reinforcement learning from human feedback (RLHF).76% similarVerifiedDuring 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.76% similarUnverifiedThe main guiding model in the developer's solution is reinforcement learning (RL), rather than an embedding model or LLM.75% similar
