arXiv:2602.16610v2 Announce Type: replace-cross Abstract: Large language models (LLMs) are increasingly applied as automatic evaluators for natural language generation assessment often using pairwise comparative judgements. Existing approaches typically rely on single judges or aggregate multiple judges assuming equal reliability. In practice, LLM judges vary substantially in performance across tasks and evaluation aspects, and their judgment probabilities may be biased and inconsistent. Furthermore, human-labelled supervision for judge calibration may be unavailable. We first empirically demo
The proliferation of increasingly capable LLMs necessitates robust and reliable evaluation methods, especially as their applications expand into sensitive areas.
Reliable AI evaluation is critical for trust, widespread adoption, and directing development, especially as AI models become more autonomous and integrated into decision-making processes.
The understanding of LLM reliability and consistency in evaluation is deepening, pushing for more sophisticated methods beyond simple aggregation of 'equal reliability' judges.
