I'm not too worried about CLI shenanigans, because of what happened with whisper.cpp - it resulted in apps like https://goodsnooze.gumroad.com/l/macwhisper - wouldn't be at all surprised to see the same happen with llama.cpp
A regular M1 with 8GB of RAM appears to be good enough to run that 7B model. I wonder at what point it will run on an iPhone... the Stable Diffusion model was 4GB when they first released it, and that runs on iOS now after some more optimization tricks.
For me though, the "Stable Diffusion" moment isn't necessarily about the LLaMA model itself. It's not licensed for commercial use, so it won't see nearly the same level of things built on top of it.
The key moment for me is that I've now personally seen a GPT-3 scale model running on my own personal laptop. I know it can be done! Now I just need to wait for the inevitable openly-licensed, instruction-tuned model that runs on the same hardware.
It's that, but also the forthcoming explosion of developer innovation that a local model will unleash. llama.cpp is just the first hint of that.
