New research suggests RL enhances language model sampling efficiency, not new reasoning

A new research paper explores how reinforcement learning (RL) impacts language model reasoning, specifically whether it introduces new reasoning capabilities or enhances the sampling of existing ones. The study introduces a Unified Decoding Framework (UDF) to analyze token-level sampling and search strategies. Results on benchmarks like Math500 and GPQA indicate that RL gains can be largely attributed to improved sampling efficiency towards existing capabilities, rather than entirely new reasoning skills.
