If you ask &#8220;Write a report on sales,&#8221; the model has to invent which sales, which period, and which format.<\/p>\n\n\n\n<p><strong>2. Ambiguous request.<\/strong> You asked for something vague\u2014&#8221;Write something persuasive&#8221;\u2014so the model defaulted to patterns in its training data, which may not match your intent.<\/p>\n\n\n\n<p><strong>3. Wrong type of task.<\/strong> You asked the model to do something it&#8217;s not designed for. Asking for precise financial data or obscure historical facts invites hallucination because the model prioritises fluency over accuracy.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The_Anti-Hallucination_Prompt_Structure\"><\/span>The Anti-Hallucination Prompt Structure<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Use this four-line structure:<\/p>\n\n\n\n<p><strong>Task:<\/strong> [Specific action you want]<br><strong>Context:<\/strong> [Background information the model needs]<br><strong>Constraints:<\/strong> [Boundaries\u2014length, format, tone]<br><strong>Grounding:<\/strong> [Facts, data, or sources the model should reference]<\/p>\n\n\n\n<p>Example:<\/p>\n\n\n\n<p><strong>Task:<\/strong> Write a 300-word summary of Q3 sales performance.<br><strong>Context:<\/strong> This is for the board meeting.
