A new study from Hugging Face investigates the effectiveness of various Large Language Models (LLMs) when used as judges for citation quality in research. The research focused on evaluating how well these LLMs could assess source relevance and factual support for claims made by search-grounded LLMs. Results indicated that less expensive models, such as GPT-5 mini, performed competitively in source relevance, while factual support scores were similar across tested models. However, significant differences in directional bias, such as false positive and false negative rates, were observed, highlighting the importance of calibrating LLM judges before using them as reward signals in reinforcement learning for research applications.
