Grounding (AI)
Grounding in AI refers to the practice of basing model outputs on verifiable, external sources rather than relying solely on the model's internal knowledge. A grounded AI response includes citations, references, or data points that can be checked against source documents. Grounding is primarily achieved through RAG (retrieval-augmented generation), where the model retrieves relevant documents and generates answers based on that retrieved context. Grounding directly reduces hallucinations and enables auditability.
In Financial Services
Real-World Example
A portfolio manager uses a grounded AI system to research a company. When asked about revenue trends, the system retrieves the specific pages from the company's 10-K, extracts the relevant figures, and generates a response with inline citations. The manager can click each citation to view the source document. Without grounding, the AI might hallucinate revenue figures or use outdated information.
Why It Matters for Finance
Grounding is what makes AI reliable enough for regulated financial use. Without grounding, AI outputs are unverifiable and potentially incorrect. With grounding, every AI-generated insight can be traced to a source, enabling trust, auditability, and regulatory compliance.

Frequently Asked Questions
What is grounding in finance AI?
Grounding is the practice of basing AI outputs on verifiable external sources with citations, rather than relying on the model's internal knowledge. It is essential for trust and auditability.
How does grounding prevent financial AI hallucinations?
Grounding forces the AI to retrieve and cite specific source documents for each claim. If the source doesn't contain the information, the AI cannot make unsupported claims, directly preventing hallucinations.
How is grounding implemented in financial RAG systems?
RAG systems ground AI outputs by retrieving relevant document chunks, providing them as context, and requiring the model to cite sources. Evaluation frameworks like Ragas and TruLens measure grounding quality.
