Some of the most impressive AI-generated images that have been created so far include those produced by DALLE 2, which is a neural network-based generative model developed by OpenAI. This AI image generator can create photorealistic images based on natural language instructions, modify images uploaded by users, and even add new elements to an existing composition in the image generation process. Another notable AI image generator is Visme's text-to-image generation tool, which is free, easy to use, and powerful, generating visuals out of plain text input. This means that users can create stunning visuals on the fly without spending hours perfecting each pixel and collaborating with their design team in real-time.
