UnverifiedThe core problem that LLM evaluation addresses is how to systematically measure output quality when model outputs are open-ended natural language, with common dimensions including accuracy, faithfulness, relevance, and safety.75% similarVerifiedLLM-as-a-judge模式即用一个能力更强的模型来评判另一个模型的输出质量，降低评测成本但引入评判模型自身的偏见问题75% similarUnverifiedThe LLM-as-Judge method was systematically validated by Zheng et al. in the MT-Bench paper, using an independent language model to score target model outputs across multiple dimensions, but it suffers from positional bias and egocentric bias.74% similarUnverified研究表明在大规模评估场景下LLM裁判（LLM-as-judge）与人工标注有较高相关性73% similarUnverifiedLLM as Judge is a technique that uses an independent judge LLM to evaluate the output quality of the main model, with evaluation dimensions including safety, relevance, and factual consistency.73% similar
