Grounding

Definition

Grounding is the practice of tying an AI model's answers to verified source material — your documentation, live data, or knowledge base — so responses reflect real facts rather than the model's own guesses.

How it works

Instead of letting a model answer purely from its training, a grounded system supplies relevant, trusted context at query time — retrieved articles, database records, or tool results — and instructs the model to base its answer on that context, often citing it.

Grounding is the goal that techniques like retrieval-augmented generation and tool use are built to achieve: the model reasons over content it can point to, not just what it happens to remember.

Why it matters for support

Grounding is the primary defense against hallucination. A support answer grounded in your current help center and live account data is accurate and specific; an ungrounded one may sound confident while being wrong. The catch is that grounding is only as reliable as the sources behind it — clean, non-contradictory content produces trustworthy answers.

Frequently asked

What is the difference between grounding and RAG?

Grounding is the outcome — answers tied to real sources. RAG is one common method for achieving it: retrieving relevant passages and passing them to the model. Tool use is another way to ground answers in live data.

Does grounding guarantee accuracy?

No. It sharply reduces errors, but the answer is only as accurate as the sources it's grounded in. Stale or conflicting documentation can still produce confident wrong answers.
