It doesn’t matter if actual copies of the original images exist, reproducing copyrighted concepts like characters is still infringement. It’s the same whether it’s done by a human or a machine. The real question is who is liable. Obviously whoever distributes the images is liable (except for those exempted by section 230) but there’s no president for the trainers.
I think there are arguments to be made for fair use with open models run by end users where there is no profit motive, but for closed models where use is paid the trainers are potentially profiting directly from the creation of infringing work.
Koboldcpp should allow you to run much larger models with a little bit of ram offloading. There’s a fork that supports rocm for AMD cards: https://github.com/YellowRoseCx/koboldcpp-rocm
Make sure to use quantized models for the best performace, q4k_M being the standard.
