Highlighted rows are where these differ.
LLMWare
- Small specialised models rather than a frontier call
- Built for regulated, air-gapped estates
Best for on-premise with no GPU budget.
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.
