Highlighted rows are where these differ.
R2R
- Ingestion, retrieval, auth and observability included
- Graph extraction built in
Best for a working RAG API without building one.
GraphRAG
- Extracts entities and relationships, then summarises communities
- Answers “what are the themes here” which vector search cannot
- Expensive to index
Best for questions no single chunk can answer.
