Assuming MS isn't conducting corporate espionage in their customers, I'd say no, not the same thing.

If they just use your questions as further training data, the information you send to them might make it into other people's hands.

No, both from a service and contractural and technical perspective using most SAAS is quite different than using ChatGPT currently.

And overall there is a reason why the USG has their own private AWS zones…

I see, may be OpenAI should offer a plan to promise only run inferencing and not inspect the data. Or may be collaborate with amazon to serve the model on private AWS zones.

This is what Microsoft is doing by brining it to Azure.

It will allow you to use the inference model and possibly even train it further on your data without having all the inputs that are going into ChatGPT right now serve as future training content.

Essentially, yes. One reason not to use them.
