ChaiNNer – Node/Graph based image processing and AI upscaling GUI

ChaiNNer predates Stable Diffusion and most of the AI craze. Its origins are in the GameUpscale community, where people were hacking and finetuning ESRGAN for 1x img2img (among other things).

Its super cool and easy, and deeply under appreciated.

There is already an AI framework named Chainer: https://github.com/chainer/chainer
