Overview

Stable Diffusion is a open-source image generation model that can run locally or in the cloud. It handles open source, local running, fine-tuning, and controlnet, and it's best suited for creators wanting open-source ai image generation. Launched in 2022, it's a relatively recent entrant that's been gaining traction.

The core product is entirely free. Since it's open-source, you can self-host for free with no user limits.
