Explain in simple terms what is a "prompt modifier" in Generative AI

In Generative AI, a "prompt modifier" is a piece of text or input that modifies or influences the output generated by a generative model. Generative models are a type of AI that are designed to generate new and original content, such as text, images, or music. They are trained on large datasets of examples and use this training to learn patterns and structures that allow them to generate new content that is similar in style and content to the examples they were trained on. Prompt modifiers are used to control or steer the output of the generative model in a particular direction. For example, you might provide a prompt modifier that specifies a certain topic or theme that you want the model to generate content about, or you might specify certain words or phrases that you want the model to include in its output. By using prompt modifiers, you can influence the output of the generative model and help it to generate content that is more relevant or aligned with your desired goals.
