Grounding
Connecting AI responses to verifiable sources of truth so it doesn't make things up.
Definition
Grounding is the practice of connecting an AI model's responses to verifiable, factual sources of information. An "grounded" AI response is one that's based on real data — documents, databases, verified facts — rather than the model's training data alone. Grounding is one of the primary defenses against hallucination.
When an AI is grounded in your company's documentation, it answers based on what's actually in those documents rather than making up plausible-sounding information. RAG is the most common grounding technique, but grounding also includes practices like instructing the AI to cite sources, cross-reference claims, and explicitly state when it's uncertain.
Examples
A legal AI that always cites the specific statute or case law it's referencing in its answers
A product support AI grounded in your knowledge base that says "Based on our documentation..." before answering
