This thing is absurd. I work in ML research and I use my Macbook Air M1 to train LLMs from anywhere, but I would never let them touch my local machine. Even if they'd run (most of them wouldn't - even on a 3080 Ti), they would ruin my battery life. So I simply connect to a GPU server via VPN and ssh + vs code remote. Only students or beginner enthusiasts might think that training this stuff on the go would actually need a beefy laptop.
