Some of y'all wonder why anyone would self host AI. Would you accept the opinion of the CEO of Microsoft?

Venture capitalists have been warning for awhile that OpenAI and Anthropic are getting access to sensitive business information. The risk is the model makers can then use that knowledge for themselves and become competitors to their own customers. We've seen Amazon do it with their own customer's IP and product designs, why wouldn't Anthropic or OpenAI?

Enter Microsoft CEO Satya Nadella:
“You essentially pay for intelligence twice, once with money, and again with something even more valuable: the proprietary knowledge you must reveal to make that intelligence useful. The better you want the model to perform, the more of that knowledge you have to feed it!” he writes.

He argues that enterprises are literally teaching the models about the nuances of their businesses.

Now what if you're just an individual inventor, researcher, author, etc? Sure, you can pay more for accounts that are supposedly walled off and exempt from training. But are they really? Satya Nadella has his doubts. And I dare say he would know.

An argument can be made that hosting your own AI is protecting your own ideas.
