Image generation
A model that produces images from a text prompt or other conditioning signal by learning the statistical structure of large image datasets.

In a nutshell
An image generation model takes a text description — or another image, a sketch, a layout — and produces pixels that match it. Most current systems are trained to reverse a process of adding noise: the model learns how noise degrades real images, then runs that process backwards at inference time. The hard part is coherence at scale: preserving geometry, respecting fine-grained instructions, and keeping outputs consistent across seeds and styles. Quality now rivals studio photography for many subjects; the gap that remains is reliable compositional control.
