What Stable Diffusion is
Stable Diffusion is a family of open-weights image models from Stability AI. You can download and run them on your own hardware, fine-tune them, or call Stability's paid API.
Stability's old DreamStudio web app now redirects to a different product, so most people use Stable Diffusion through their own setup or a third-party app.
What Stable Diffusion is good at
- Self-hosting for free under the Community License (under $1M annual revenue)
- Fine-tuning and full control of the model
- A per-image API with inpaint, outpaint, erase, relight and upscale endpoints
