[P] Public API for open LLMs like llama.cpp with pay-per-use ?

Are there such service already ?
If no would it be useful given:

* The need for setup
* The required computing power

?

Big cloud providers like AWS provide a lot of AI services but AFAIK I can't see such thing for open LLMs.

*LLM curated Google search did not tell me that already exists*
