The authors followed open-model training histories, including OLMo-3 checkpoints, released RL trajectories, and models fine-tuned on reasoning traces.
Reasoning models usually inherit “wait” from training data, not reinforcement learning
Across open-model training histories, the authors find that reinforcement learning can improve mathematics accuracy without introducing “wait”, while different training recipes amplify or erase an inherited marker.
