What each one is
GraphRAG
GraphRAG from Microsoft Research extracts entities and relations into a knowledge graph before retrieval, dramatically improving answers to global, multi-hop questions over large corpora.
- Answers global questions plain RAG misses
- Structured, explainable retrieval via graph communities
- From Microsoft Research with active development
FlashRank
FlashRank re-ranks retrieved passages with tiny cross-encoder models, sharply improving RAG answer quality at almost no cost.
- Big RAG quality gain for a few lines
- Tiny models, runs on CPU
- No API calls needed
