I've attached a video below. It's about LLM's and this will give you a strong foundation to understanding Ai models.
I want you to watch it and keep a pen + paper to make notes.
The purpose of making notes is not for you to read them later (which you can) but the actual reason is that when you write while you're learning, It's categorized better inside your brain and you're able to recall that particular set of information faster.
