Self-Play Search Distillation for Large Language Model Reasoning

Self-Play Search Distillation (SPSD), a framework for generating superhuman synthetic data via self-play of MuZero-like networks trained on board games, offers an annotation-efficient way to create high-quality synthetic data for improving LLM performance in reasoning tasks.

LLMs (Almost) Never Abstain Under Medical Uncertainty

MedQAbstain is introduced, a benchmark explicitly designed to evaluate medical abstention under uncertainty, and finds that state-of-the-art LLMs systematically overcommit, rarely abstaining even when the question itself is hidden.
