...is a GTK+ application for generating images with Stable Diffusion. It uses diffusers to do the actual inference and downloads the model from huggingface when first used. Initial downloading might take a while, but the model will be cached for later use.
Sadly the current way of handling the model cache prevents you from using the application offline, even though the models are cached. You can take a look at this issue on the diffusers repo.
I haven't gotten around to properly packaging the application yet, so for now your best option is to run it with poetry like so:
poetry install
poetry run python src/sdiff_gtk/__init__.py
Note that you might have to install gobject-introspection package on your system, as it is required to build the python package gobject.
You can install this program from the AUR.
It is available as sdiff-gtk.
