InfoDensity: Rewarding Information-Dense Traces for Efficient Reasoning

Researchers propose InfoDensity, a reinforcement learning reward framework that optimizes Large Language Models for efficient reasoning by measuring information density rather than just output length. The method tracks entropy trajectories to identify high-quality intermediate reasoning steps, achieving better accuracy-efficiency trade-offs on mathematical and general reasoning benchmarks.

Revisiting the Uniform Information Density Hypothesis in LLM Reasoning

Researchers challenge the Uniform Information Density hypothesis in LLM reasoning, finding that high-quality reasoning exhibits locally smooth but globally non-uniform information flow. This counter-intuitive pattern suggests LLMs optimize differently than human communication, with entropy-based metrics effectively predicting reasoning quality across seven benchmarks.
