arXiv:2510.09278v2 Announce Type: replace-cross Abstract: Training expert LLMs in domains with scarce data is difficult, often relying on multiple-choice questions (MCQs). However, standard outcome-based reinforcement learning (RL) on MCQs is risky. While it may improve accuracy, we observe it often degrades reasoning quality such as logical consistency. Existing solutions to supervise reasoning, such as large-scale Process Reward Models (PRMs), are prohibitively expensive. To address this, we propose CLARity, a cost-effective RL framework that enhances reasoning quality using only a small, ge
The continuous drive for more efficient and effective AI training methods, especially for LLMs, makes research into cost-effective reasoning supervision highly relevant.
This development could significantly lower the barrier to training high-quality expert LLMs in data-scarce domains, moving towards more capable and autonomous AI systems.
The methodology for improving LLM reasoning quality shifts away from expensive, large-scale process reward models to more accessible and cost-effective consistency-based approaches.
