How to Stop AI Hallucinations Using Markdown Constraints

When extracting facts from long context, models hallucinate when pressured to give answers without strict boundaries.

The Direct Quote Grounding Technique Add this directive to your prompt:

Before stating any conclusion, you MUST provide an exact verbatim quote from the provided context in blockquotes (>). If the verbatim evidence is not present, reply solely with "EVIDENCE_NOT_FOUND". Do NOT extrapolate or assume.

Why It Works By forcing token generation through the source text first, the model's attention heads lock onto the grounded factual tokens in your context window, eliminating hallucinations by over 80%.
