Researchers have developed a new method called DASH (Drift Aware advantage SHaping) to address overthinking in reasoning language models. This technique assigns credit at the segment level, determining whether each part of the reasoning process moves closer to or further from a correct answer. By using intermediate answer commitments as a proxy for productivity, DASH avoids the need for costly step-level annotations. Applied to competition-level math benchmarks like AIME25, DASH has demonstrated higher accuracy and reduced unproductive self-reflection compared to existing methods. AI
