Stable Diffusion
Open-weight image models you can run on your own hardware.
Stable Diffusion's models are downloadable, so images can be generated locally with no per-image cost and no content passing through someone else's servers. The trade-off is setup: you need a capable GPU and some willingness to configure things.
Our take
The choice when volume, privacy or precise control matter more than convenience. For occasional images, a hosted service costs less than the time spent setting this up.
