Having an always-on machine running LLMs locally at home while on the move with a lightweight machine - Experiences?

Hi! I’m currently retraining in data science and my current laptop is an 8 GB MacBook Air, so naturally I’m looking to upgrade. I’m also interested in AI and running LLMs locally, and Ive been thinking about two options: a) Get a MacBook Pro with 48-64 GB RAM b) Get a Mac Studio / Mac mini with 64 G
