• TLDR：RetrievalRouter is a lightweight query-aware router that learns, from the query text alone, which retrieval pipeline best fits each query, and achieves significantly higher nDCG@5 across accuracy-oriented settings, while matching or numerically outperforming them on both nDCG@5 and latency in latency-oriented settings.

• 标题中文：RetrievalRouter：面向文档检索的模态与架构联合选择
• TLDR中文：RetrievalRouter 是一种轻量级 query-aware router，仅依据 query 文本即可学习最匹配的检索 pipeline，在面向准确率的设置下 nDCG@5 显著更高，而在面向延迟的设置下，nDCG@5 和延迟均匹配或数值上优于基线。
