I doubt that Microsoft has an agreement with OpenAI that would allow Microsoft on-prem model deployment to third parties. The danger is too high that the GPT-4 weights would leak. They are probably worth billions of dollars.
Yes but you need quite expensive hardware to run it, I doubt the magic that goes into building the weights can be gleaned from them, and anyone using it (in certain jurisdictions) can be destroyed in court.
I understand they want to protect their IP but I don’t think the model leaking will cost openai billions.
