I'm in the same boat. We have customers that need to run models in an environment that have access to the public internet, even if they did trust OpenAI et al.
More importantly for me, I don't want to be beholden to a model provider and have to take what they give me. I'd rather host my own model if an API was an option, because then I have control over it and can hack it as I want. I don't want to be just a wrapper on GPT which is sort of what you're stuck with if you just want to use their APIs.
