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.
