Banner prompts are AI prompts for quickly shaping horizontal ad images for web, app, and social campaigns. In Carat, you can generate images or video with models like GPT Image 2, then keep going with follow-up work such as editing the result, changing the aspect ratio, removing the background, upscaling, or converting to video.
Banner work is less about simply making something that looks good and more about its purpose. A banner has to communicate its purpose at first glance. Setting clear priorities for the headline, white space, CTA, and brand color—ahead of the product or person—makes it usable on a real landing page or ad placement. When choosing a prompt, look first for examples that show the subject, composition, style, text placement, and intended channel together.
In Carat, once you run a prompt you can refine from the result you like, or continue with follow-up work like changing the aspect ratio, removing the background, upscaling, or converting to video.
