Yes but if a 7b LLM will give you the same “Hello World” as the 70b, and that’s literally all you need, using a bigger model is just burning energy for no reason at all.
The cost is fixed for me at least at this point so why would I choose the inferior version.
It’s not fixed whatsoever. Mistral 7B runs on a MacBook Air, and it’s free. Zero cost LLM, no network latency.
