Run-Your-Custom-Model Stable Diffusion Site
Let hobbyists upload their own Stable Diffusion checkpoints and LoRAs and generate in the cloud, for a monthly fee.
In plain English
Hobbyists whose own computer is too weak for heavy picture-making can upload their own saved styles and generate images online. The site lines the requests up, makes the pictures, and keeps a gallery, all for a monthly fee. They pay because they want their own styles, not only the ones a public site already offers. The AI does almost all of the picture-making and the payment handling. The person running the site still looks after the strong computers that do the drawing, and reviews uploads so unsafe files do not stay online.

Overview
sphuff launched stadio.ai in December 2022 and reported $700 MRR by Jan 22, 2023. That’s self-reported on HN and there’s no later update. Check whether the site is still live before you publish.
Risks
- A crowded field now (Civitai on-site generation, RunDiffusion, ThinkDiffusion).
- Moderation of user-uploaded models (NSFW, likeness, copyright).
