LightRAG: The Simplest and Fastest RAG

LightRAG is a simple and fast retrieval-augmented generation (RAG) system that can be used for various natural language processing tasks. It supports both OpenAI and Hugging Face language models, and provides different search modes (naive, local, global, and hybrid) for querying the system.
