TBH I never understood people trying to run LLM locally. Just rent a powerful machine in the cloud for few hours. It's cheap enough, because you don't need to own a hardware. It doesn't introduce a dependency because there are hundreds of hosters. It doesn't compromise your data, because nobody would extract data from your VM, not until you're under an investigation, anyway, and even in that case just use different jurisdiction.

Spending humongous amount of money to get machine that'll felt obsolete in 2 years? I don't know.
