Core Concepts
PipeRAG introduces a novel approach to improve generation efficiency through pipeline parallelism, flexible retrieval intervals, and performance modeling.
Abstract
PipeRAG aims to enhance the efficiency of retrieval-augmented generation by introducing pipeline parallelism, supporting flexible retrieval intervals, and dynamically adjusting retrieval quality. By combining these methods, PipeRAG achieves significant speedup in end-to-end generation latency while maintaining or improving generation quality. The approach addresses hardware inefficiencies, increases inference time with sequence length, and optimizes search quality and latency in large-scale vector search. Evaluation results demonstrate the effectiveness of PipeRAG in various datasets, highlighting the importance of algorithm-system co-design in optimizing retrieval-augmented generation.
