VoltaML for stable diffusion imagegen (as AITemplate is really fast, and controlnet and LORAs are super useful)
Llama.cpp for textgen... I use the koboldcpp frontend (and sometimed AI Horde) for experimenting with models, though I am still figuring out the exact stack I want for productivity. I am watching this PR closely:
https://github.com/ggerganov/llama.cpp/pull/1773
As well as Starcoder/Openllama finetunes for summarization, codegen and such.
