AI image generators like DALLE 2, Craiyon, and NightCafe use machine learning algorithms to generate new images based on a set of input parameters or conditions. These tools allow users to generate high-quality images quickly and easily by entering a text prompt. The AI image generator then combines concepts, attributes, and styles to create a matching image. Some AI image generators, like DALLE 2, also offer features such as outpainting, inpainting, and variations to further customize the generated image. To train the AI image generator, a large dataset of images is used, which can include anything from paintings and photographs to 3D models and game assets. These AI image generators are becoming increasingly popular and are being used in a variety of applications, from creative brainstorming to enhancing the detail of images.
