Learning LLM internals != using them as daily tools (the latter was the topic of discussion).

Shifting to the learning topic: no need for expensive hardware. Even a 16 GB GPU will do, and that's (relatively) cheap and available.

Training models vs modelling trains

Don't bite. You're right.

Having spent a good weekend learning how to perform latent-steering through playing with pytorch and a local Gemma4 model, there is no way I could have groked any of that in the the way I did without hands on time.

This is on an M3 Max 36GB I've had for a couple of years. No further outlay needed.

My thinking is totally aligned with yours, perhaps its because I am trying to do a second act at almost 50 from blue-collar to white collar office work. I have no formal degree, but I have been hobby programming for 20 years. I have made a habit of "letting myself be available to all lessons"... the localllama group has made this journey really fun if nothing else. I have learned an ABSOLUTE ton from this era!
