Negative Prompt
A negative prompt tells an AI model what to avoid or exclude from the generated image, refining outputs by subtraction.
Negative prompts are a second input field (in models that support them) where you describe attributes you don't want in the output. Instead of fighting the model through repeated generations, you tell it directly: "no text, no watermark, no extra fingers, not photorealistic."
Used well, negative prompts cut iteration count significantly. They're particularly useful for removing common generative artifacts (blurry backgrounds, extra limbs, over-saturated colors) and for enforcing stylistic constraints.
Overused, they can flatten outputs — removing too much variety and making the model overly cautious. The best approach is minimal, targeted negative prompts specific to the actual problems you're seeing.
