Yes, TBH one of the reasons i want to try and finetune my own is to teach it stuff that now i have to explain before anything can be done :-P.

Unfortunately i only have a 24GB GPU - and an AMD one at that - so there isn't much i can do on that front. Supposedly a 24GB GPU is enough for finetuning a 24B model with 4bit QLoRA, though when i tried it with some finetuning app (in an official docker container) it barfed at Mistral's weird template or something and i lost interest after that.
