## What it is
FlashRAG is a modular Python toolkit for reproducing and developing Retrieval-Augmented Generation (RAG) research, bundling 36 pre-processed benchmark datasets and 23 state-of-the-art RAG algorithms including reasoning-based methods. It offers customizable components, preprocessing scripts, and an easy-to-use UI (FlashRAG-UI) for building and evaluating RAG pipelines.

## Use cases
- reproduce state-of-the-art RAG algorithms on benchmark datasets
- build a custom retrieval-augmented generation pipeline in Python
- compare RAG methods in a unified evaluation framework
- run RAG experiments with pre-processed benchmark datasets and corpora
- prototype reasoning-based RAG methods that interleave retrieval with reasoning
- evaluate LLM question answering with retrieval augmentation

## When to choose
- you need a lightweight, modular research framework for RAG experiments rather than a heavy production framework
- you want ready-made implementations of many RAG algorithms and benchmark datasets for fair comparison
- you are a researcher reproducing or extending published RAG methods

## When to avoid
- you need a production-grade RAG application with enterprise integrations rather than a research toolkit
- you want a simple plug-and-play RAG chatbot without configuring retrieval, corpus, and generation components
- your use case is general LLM application orchestration outside of retrieval-augmented generation
