Think or Not? Exploring Thinking Efficiency in Large Reasoning Models via an Information-Theoretic Lens

NeurIPS 2025spotlight

The recent rise of Large Reasoning Models (LRMs) has significantly improved multi-step reasoning performance, but often at the cost of generating excessively long reasoning chains. This paper revisits the efficiency of such reasoning processes through an information-theoretic lens, revealing a funda…
