arXiv:2606.03980v1 Announce Type: cross Abstract: Reward models (RMs) provide critical feedback signals for LLM post-training, notably in reinforced fine-tuning (RFT) and reinforcement learning (RL) pipelines. However, current reward evaluation relies on heterogeneous criteria such as rule-based verifiers, ground-truth references, procedural checklists, and complex rubrics, where a unified mechanism to integrate all types of evidence remains unexplored. To this end, we propose Skill Reward Model (Skill-RM), a unified framework that reformulates reward modeling as the execution of a reusable Re
The rapid advancement of large language models (LLMs) and the increasing complexity of their evaluation necessitate more sophisticated and unified reward modeling frameworks.
A unified approach to reward modeling can significantly improve the performance and reliability of AI agents by providing more coherent and comprehensive feedback during reinforcement fine-tuning.
The proposed Skill-RM framework unifies heterogeneous evaluation criteria, potentially leading to more robust and versatile AI agents compared to current fragmented evaluation methods.
