FlashRAG

FlashRAG is a Python toolkit designed for the reproduction and development of retrieval augmented generation research.

FlashRAG is a Python toolkit designed for the reproduction and development of retrieval augmented generation research. The toolkit includes 36 pre-processed benchmark datasets and 23 advanced algorithms, featuring reasoning-based methods that combine reasoning ability with retrieval. It includes essential components such as retrievers, rerankers, generators, and compressors for building pipelines. Users can configure and experience RAG baselines through an included user interface. The framework supports tools like vLLM, FastChat, and Faiss for optimized execution.
