FlashRAG

FlashRAG by RUC-NLPIR is a Python toolkit for reproducing and developing retrieval-augmented generation research. It bundles a large set of preprocessed benchmark datasets and many state-of-the-art RAG algorithms, including reasoning-based methods that combine retrieval with multi-step reasoning, behind a unified framework with evaluation utilities and an optional UI. It lets researchers reproduce existing work or build custom RAG components. Released under the MIT license.
