# This uses https://github.com/asomoza/image_gen_aux/blob/main/src/image_gen_aux/upscalers/README.md
# Also this space has been duplicated from their official huggingface space, https://huggingface.co/spaces/OzzyGT/basic_upscaler
# They did great work, and I was happy to see them to also use my models :) I thought Id duplicate it and extend it.
# It basically made me get a pro account so I can make a Zero GPU space. And I will also upload more of my models as a model card now to use here.

# Start out with my own models. If others like kim, sirosky, and other model trainers would like their models added here, then thats great.
# I simply want them to message me first so I know that everythings okay with having their model as a selection here since they are the author of that model. If they want their model on here or not basically.
# I load models from huggingface model cards though, so the model should be hosted on huggingface.
