I fine tuned LLama-2 on code/comment generation (in python) for around $2 and was able to run it natively on an m1 macbook air. I can totally see smaller fine tuned LLM's being used locally on consumer devices in the future. I think people underestimate how cheap and efficient this stuff is.
I've actually built a service which lets you fine tune LLama-2/other llms by uploading a JSON dataset. I'm looking for feedback, the link is https://useftn.com.
