What is AI Image Generation?

AI image generators start with random noise and iteratively denoise it into a coherent image, guided by your text prompt. This process typically takes 3-30 seconds depending on the model.

Describe an image in natural language and AI generates it. Modern models understand composition, lighting, style, and abstract concepts from text alone.

Generate images in any visual style: photorealistic, oil painting, anime, 3D render, watercolor, or pixel art. Style is controlled through prompt keywords or model parameters.

Top models produce images at 1024x1024 or higher. Midjourney v7 supports ultra-high resolution output, and Flux 2 excels at accurate text rendering within images.

Edit specific regions of generated images. Remove objects, change backgrounds, or modify details while keeping the rest of the image intact.

Flux 2 (Apache 2.0) and Stable Diffusion (open weights) can be self-hosted for free. API access costs as low as $0.003 per image through third-party providers.
