That would actually be insane. Right now, I still need my GPU and about 8-10 gigs of VRAM to run a 7B model tho, so idk how that's supposed to work on a phone. Still, being able to run a model that's as good as a 70B model but with the speed and memory usage of a 7B model would be huge.
I only need ~4 GB of RAM/VRAM for a 7B model, my GPU only has 6GB VRAM anyway. 7B models are smaller than you think, or you have a very inefficient setup.
llama2 gguf with 2bit quantisation only needs ~5gb vram. 8bits need >9gb. Anything inbetween is possible. There are even 1.5bit and even 1bit options (not gguf AFAIK). Generally fewer bits means worse results though.
Yeah, I usually take the 6bit quants, didn't know the difference is that big. That's probably why tho. Unfortunately, almost all Llama3 models are either 8B or 70B, so there isn't really anything in between but I find Llama3 models to be noticeably better than Llama2 models, otherwise I would have tried bigger models with lower quants.
