How do I stop AI from making up false info in my business?
You can't fully stop hallucinations, but you can contain them. Ground AI in your own sources with retrieval (RAG), require citations and quotes you can verify, explicitly permit 'I don't know,' and add a human check before anything high-stakes is published. The core principle: never let AI assert facts it can't trace to a source. For numbers, names, legal, or medical claims, treat every AI output as a draft to verify, not a truth.
Reduce hallucinations at the source. Use RAG so the model answers from your documents rather than memory, and instruct it to quote the supporting passage and say 'I don't know' when the answer isn't in the provided material. Lower 'temperature' for factual tasks, and break complex asks into steps. Grounded, source-restricted prompts hallucinate far less than open-ended ones.
Add verification as a workflow, not a hope. For published or decision-driving content, route outputs through a check: does every factual claim have a cited source? Do the citations actually exist and say what's claimed? AI fabricates plausible-looking references, so verify links and quotes against the real source. A second AI pass can flag unsupported claims, but a human owns the final sign-off on high-stakes items.
Build prompt templates with guardrails baked in: 'Answer only from the text below. If the answer isn't there, say you don't know. Cite the exact sentence you used.' Reserve the strictest checks for high-risk areas, finance, legal, medical, and any external-facing claim, where a confident wrong answer does real damage. Audit a sample of your current AI outputs to see where fabrication is slipping through, then tighten those prompts.
