Stable Diffusion is a free, open source AI-based system that generates images from text descriptions or prompts.  

Trained on pairs of images and captions taken from LAION-5B, the system was initially restricted to researchers as Stable Diffusion 1. It was publicly released as Stable Diffusion 2 in August 2022.


Stable Diffusion quickly became popular largely on account of its free availability, minimal usage restrictions, and the fact that it can run on ordinary consumer hardware.

But it is seen to suffer from a number of technical limitations, and to pose several actual and potential challenges and risks to organisations and individuals operating and using it:


Unlike DALL-E, Stability AI has made Stable Diffusion accessible courtesy of a public demo, a software beta called DreamStudio, a development notebook, and weights, model card and code.

The company also appears to have listened to feedback from users and artists as Stable Diffusion 2 has most NSFW content, celebrity images and famous artists’ names removed

It has also made it easier to find out whose work is in the dataset, thereby making simpler for artists to opt-out.
