Highlighted rows are where these differ.
Unstructured
- PDF, DOCX, HTML, email and more into elements
- The unglamorous layer most RAG failures actually come from
Best for the ingestion step nobody enjoys writing.
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.
