Highlighted rows are where these differ.
Haystack
- Every step is declared, which is what audits need
- Cleanest option where a wrong answer has consequences
Best for finance, health, legal and government.
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.
