A new arXiv preprint introduces 'Rubrics on Trial,' a query-only framework that automatically constructs and validates evaluation rubrics for LLMs without external annotations or model training. The system evolves rubric sets from scratch using synthetic rubric-conditioned response pairs, screening out non-discriminative, over-specific, or style-only rubrics. Evaluated across five preference benchmark suites, it achieves best average accuracy and leads on six of seven evaluation sets, addressing a key bottleneck in scalable LLM evaluation.
