What is RAG, and why it matters

6 minSystems & architecture

Most trustworthy enterprise AI is retrieval-augmented. Here is what that means, in plain terms, and why it is the difference between a demo and a system you can rely on.

Ask a general AI model a question about your business and it will answer confidently — sometimes correctly, sometimes not. It has no access to your documents, and no way to show its work. For enterprise use, that is a non-starter. Retrieval-augmented generation (RAG) is the pattern that fixes it.

How RAG works, briefly

Instead of relying on what a model memorized in training, a RAG system retrieves the relevant passages from your approved sources at question time, and asks the model to answer grounded in those passages — with citations back to the source. The model becomes a reasoning layer over your knowledge, not a stand-in for it.

Why it matters for the enterprise

Most of the systems Celadon builds are retrieval-augmented for exactly these reasons: grounded, cited, governed answers over real business knowledge.

RAG is necessary, not sufficient

Good retrieval is where AI quality is won or lost — but it still needs evaluation, access control, and a workflow that fits how people actually work. That is the architecture-first approach behind every Celadon build.
