A prompt is the content you enter into a generative AI tool to query the application for some type of output. This output might be text, image, or some other type of product. The quality of the output you receive will depend in part on the quality of the prompt you provide. Users often find they need to revise and refine their prompt to obtain the desired results.
Prompt engineering is the process of structuring text (or other input) in order to obtain quality results.
