Poster prompts are AI prompts for quickly shaping images that capture an event, movie, or brand message in a single piece. 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.
With posters, the purpose matters more than simply making something that looks good. A poster needs an eye-catching subject and information layout at the same time. Designing the main visual, title area, white space, color, and print texture together gets you a result that fits both online and offline. When choosing a prompt, look first for examples that show the subject, composition, style, text placement, and intended channel.
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.
