LightRAG and RAG-Anything
LightRAG is a lightweight retrieval-ranking-fusion method optimized for speed and simplicity, while RAG-Anything is a comprehensive framework that could incorporate LightRAG's approach as one of its modular components, making them complements rather than competitors.
About LightRAG
HKUDS/LightRAG
[EMNLP2025] "LightRAG: Simple and Fast Retrieval-Augmented Generation"
Constructs a dual-level retrieval system combining vector similarity search with knowledge graph extraction to handle both entity-centric and content-based queries. Supports multiple storage backends including Neo4j, MongoDB, and PostgreSQL, with integrated reranking, citation tracking, and multimodal document processing via RAG-Anything. Designed for Python 3.10+ with built-in evaluation (RAGAS) and tracing (Langfuse) capabilities.
About RAG-Anything
HKUDS/RAG-Anything
"RAG-Anything: All-in-One RAG Framework"
Supports multimodal document analysis including images, tables, and equations through specialized processors and a unified knowledge graph. Built on LightRAG with adaptive parsing modes—either MinerU-based document processing or direct content injection—enabling flexible integration with external parsing pipelines. Integrates vision-language models for enhanced visual query understanding while maintaining compatibility with diverse file formats and enterprise knowledge management workflows.
