Image prompt
An image prompt is a description given to an image generation model specifying the subject, setting, composition, lighting, and style of the picture to produce.
Image prompts are not written like chat prompts. Diffusion models respond to weighted descriptors rather than sentences, so a comma-separated stack of concrete visual attributes outperforms a well-written paragraph.
