In my experience my players are excited about the rules and how their characters work - but not all of them learn well from "just reading the rules", like it literally does not stick. Just telling them to read the rules isn't going to do anything but make them feel shitty about the game.
Talk to your players about how to help them remember or have easy access to these rules. Make sure you don't get too accusatory, you do want to play with these people after all.
I mean yeah it is a language model that is trained on things other people write and learn what the next word should be from that (and some blackbox stuff). It's fun to play around with for sure, but we as user need to be better at understand what the tech actually is rather than just pretend it is a Sci-fi AI... Because holy shit it is not, all that AI stuff is marketing and tech people trying to make us think it is just like in that movie we like or whatever... Why I try and be so hard about LLM as the term rather than AI.
