Not much, but you can use it for basically anything people use frontier models for, it'll just be somewhat dumber. I occasionally run LLMs for proof-reading important things that I've already hand-written and edited. Sometimes for bouncing off ideas. Sometimes for the kinds of questions I'd normally chuck at a forum but I can get a quicker answer if I ask an LLM. No, I don't "trust" the answers; anything where I can't just use my own judgement, the LLM will have given me enough to perform my own research to fact-check it.

Radeon RX 7600, but yes, you're right, it's relative. It's good enough for any gaming I do, which is not an awful lot. I think it's considered mid-range for its generation, I guess I was just thinking of the GPUs I see people mention they have which seem much beefier than mine lol.

I'm no AI expert but when I looked into it, it seemed that VRAM was the biggest factor being mentioned in discussions of GPUs, hence why I mentioned it.
