HKUDS/LightRAG — Lightweight GraphRAG Alternative
A lightweight alternative requiring significantly fewer tokens and API calls.
LightRAG achieves comparable quality with 70% fewer tokens consumed during retrieval, faster indexing time, simpler architecture, support for incremental graph updates, and multiple backend support. It uses a simplified graph construction approach that trades some hierarchical community structure for speed.
