DeepSeek's new study explores the effectiveness of learned stopping in reasoning models, finding that it can improve performance in certain tasks. The study introduces LearnStop, a hidden-state-free checkpoint stopper, and evaluates its performance across 18 task-model settings. The results show that learned stopping can be useful in tasks where many questions become correct before full budget but do not exhibit a single reliable scalar stopping signal.

New research from arXiv challenges conventional wisdom on AI improvement from feedback, revealing that multi-turn gains often mask true learning. The study highlights that an AI model's ability to effectively *utilize* feedback, rather than merely receiving it, is the critical bottleneck for interactive improvement, especially when compared to unguided self-refinement or simple retries.
