Microsoft CEO Satya Nadella issued a warning to companies relying on proprietary AI labs for their artificial intelligence needs, on CNN’s Fareed Zakaria GPS. When Zakaria asked Nadella to explain what constitutes a company sharing too much with an AI model provider, Nadella said businesses need to be wary of everything they hand over, from their data to their prompts.
Nadella called for a setup where “every time you use the model, all of the metadata around it is retained by you, so that you could use all of that to train perhaps your own weights or your own open model.” (Weights are a model’s trained parameters — essentially its brain. Nadella’s point: Companies should hold on to their own usage data so they can eventually build a model of their own.)

“Any firm that doesn’t have this control, I will claim will not remain a firm because you’ve essentially outsourced your thinking,” he added.
In short, Nadella said that companies without their own models — or without a layer of AI infrastructure known as AI gateways to separate their prompts from the model itself — will be in trouble. In particular, Nadella wants to stop relying on AI labs’ built-in coding tools, known as harnesses. (Anthropic’s Claude Code and OpenAI’s ChatGPT Codex are examples of these.)
“By keeping the harness separate from the model and the context and memory separate from the model, you absolutely can use multiple models for what they’re great at. At the same time, any one model can go away, and you can still continue to be in control of your own destiny,” Nadella said.
This comes a month after the Microsoft CEO warned of a future in which a handful of AI providers capture most economic value while industries lose ownership of their knowledge.

“The last thing any of us want is a world where every company across every sector is ceding value to a few models that eat everything they see,” Nadella had written. “There is no societal permission for an AI future that hollows out entire industries.”
Nadella had also warned enterprises using AI about the “reverse information paradox” which could lead to the company having to pay twice — once in cash, once in proprietary knowledge.
A TechCrunch report noted Microsoft is an investor in the two largest AI labs, Anthropic and OpenAI. However, Microsoft’s cloud business is also now also selling the kind of alternative infrastructure he’s recommending.
