Concept · [Building with AI](https://ecosystem.samcarlton.com/ai)

Also called: diffusion, diffusion models, image generation model, text-to-image, image generator

A kind of [AI model](https://ecosystem.samcarlton.com/model) that creates images, and sometimes audio or video, by starting from random noise and removing it step by step until a picture that matches the [prompt](https://ecosystem.samcarlton.com/prompt) appears.

**For example:** A designer types 'a red bicycle on a Tulsa street at sunset' and a diffusion model produces the image in seconds.
