- What is RAG, and when do we need it?
- RAG (retrieval-augmented generation) looks up the relevant passages in your own data and hands them to the model with the question, so answers come from your sources, not the model’s memory. You need it when answers depend on information the model was never trained on, or that changes.
- Why not just use a model with a huge context window?
- For a handful of documents, that can work, and we’ll tell you if it’s enough. Across thousands of documents it gets slow and expensive, and it can’t enforce who may see what. Retrieval sends only the passages that matter, from documents the user is allowed to open.
- Do we need a new vector database?
- Usually not. If you run Postgres, pgvector is often enough; if you already use OpenSearch or Azure AI Search, we build on it. We choose the store on your volume, latency and operations needs.
- How do you stop it making things up?
- Every answer must cite the passages it uses, and the system says it doesn’t know when the sources don’t cover the question. On every release we test groundedness — whether each claim is supported by its source — alongside retrieval recall.
- Can it respect our document permissions?
- Yes. Access rules from your source systems are stored with each chunk and checked at query time, so people only get answers from documents they can already open.
- We already built a RAG prototype. Can you help?
- Yes. We measure it on your real questions, find where it fails — parsing, chunking, retrieval, reranking or the prompt — and give you a fix plan priced item by item. Our $4,500 AI System Audit does this in 5 business days.
