[counterintuitive] Instructing the model 'Do not hallucinate' or 'Ensure your answer is 100% accurate'

Ground the model with retrieved context \(RAG\) and force citation of specific source documents for every claim.

Journey Context:
Telling an LLM 'don't hallucinate' is like telling a fish 'don't swim'—it's fundamentally against their generative nature. This prompt hack occasionally worked by making the model more conservative \(increasing 'I don't know' responses\), but it doesn't actually verify facts. The modern replacement is architectural: provide the facts via RAG, and use structured prompts that require the model to extract and cite specific snippets from the provided context, making ungrounded answers structurally obvious.
