I use ChatGPT for most practical stuff but I really enjoy running local models. I find it really interesting and I think it's important for people to know how to run these without being beholden to big tech. If you have a used 3090 you can already run some really strong models. There are some really interesting local models as well, like the abliterated ones.
Running locally has a lot of advantages - privacy, getting to learn how to run LLMs, not having to deal with quotas, logins, outages.
