Negative Prompt
An instruction that tells the model what to avoid or exclude in its output.
Full Definition
A negative prompt explicitly lists undesired content, styles, topics, or formats, complementing the positive instructions in a prompt. In image generation (Stable Diffusion, Midjourney), negative prompts directly subtract visual concepts from the output. In text, they are expressed as 'do not include', 'avoid', or 'exclude' clauses. Negative prompts are most useful when a model consistently adds unwanted elements — disclaimers, hedging language, specific topics — that positive instructions alone have not eliminated. They work best when specific rather than generic: 'do not include citations' outperforms 'keep it clean'.
Examples
Stable Diffusion prompt: 'a mountain landscape at sunset — negative: people, buildings, cables, overexposed sky'.
Text prompt: 'Explain quantum entanglement to a 10-year-old. Do not use the words 'particle', 'wave', or 'physics'.'
