    abstract = "Retrieval-Augmented Generation (RAG) plays a pivotal role in modern large language model applications, with numerous existing frameworks offering a wide range of functionalities to facilitate the development of RAG systems.However, we have identified several persistent challenges in these frameworks, including lack of new techniques, difficulties in algorithm reproduction and sharing, and high system overhead.To address these limitations, we introduce **FlexRAG**, an open-source framework specifically designed for research and prototyping.FlexRAG supports text-based, multimodal, and network-based RAG, providing comprehensive lifecycle support alongside efficient asynchronous processing and persistent caching capabilities.By offering a robust and flexible solution, FlexRAG enables researchers to rapidly develop, deploy, and share advanced RAG systems.Our toolkit and resources are available at https://github.com/ictnlp/FlexRAG."
