The paper reports 31% fewer reasoning tokens on Qwen3-32B across seven benchmarks without lower aggregate accuracy, plus 20% fewer thinking tokens in coding self-debug tasks. Public code is available, but the results are author-reported and the reference setup requires an 80 GB GPU.</p><p>Recommendation: TRIAL</p><p>Sources: <a href="https://arxiv.org/abs/2610.14745">DoubtLess: Efficient Reasoning via Contrastive Decoding</a> · <a href="https://github.com/zhangshaowei1023/DoubtLess">DoubtLess repository</a></p>
