Negative prompt
A negative prompt is text that tells an AI image model what to leave out — blur, extra fingers, watermarks, text. While generating, the model actively steers away from the patterns you list.
Guidance works in both directions. The prompt pulls the generation toward what you described; the negative prompt pushes it away from what you did not. It is most valuable for failure modes the model is known for — distorted hands, plastic skin, stray captions — because naming them makes them less likely, not more.
A concrete example: the same portrait prompt with the negative prompt "cartoon, blurry, deformed hands, watermark" produces noticeably cleaner skin and correctly counted fingers, because the denoising is penalised every time it drifts toward those patterns.
How Hermosso uses it: instruction-following tools like the AI Image Editor accept both what to add and what to avoid, and Moodboards lock in a style profile so you stop repeating the same exclusions on every run.
