shouldn't your willingness to pay/not pay be a function of your experience and the value the product delivers you, rather than an implementation detail such as fine tuning vs prompt engineering?

I think this difference should be comparable to asking something like:

This website uses UsersDb, which makes me think you have built a custom database, but if you can easily switch between sqlite and postgres, that makes it seem like there's no real work happening. Could you shed some light on this?

I feel this comparison is almost entirely valid since fine tuning can be as simple as:

- Create request/response tabular data

- Click "upload" on leading LLM provider

- Click "fine tune"

- Change your code to reference llm.com/finetuned instead of llm.com/base-model
