Would you be able to actually get useful results from it? I'm looking into self hosting LLM's for python/js development. But I dont know if I would get useful results.

I have been thinking the same and have tried a little. I have tried some small models and got some useful results.

I have not figured out what models that fit in the available memory (say 16Gb) that would be best for doing this. A CPU model I can run on a laptop would be nice. The models I have tried are much smaller than 30B.
