Reinforcement Learning Alters Language Model Behavior

On LessWrong, a post shares reflections on how reinforcement learning applied in post-training may be affecting language models. The piece examines potential shifts in model outputs, behavior, evaluation, and robustness resulting from post-training reinforcement learning adjustments.
Scoring Rationale
Thoughtful commentary on post-training RL effects is useful for researchers and practitioners but does not present new empirical results, so it ranks as a solid, mid-tier contribution.
