Satya Nadella warns companies: Using AI may cost more than you think
Microsoft CEO Satya Nadella published a blog post on Monday warning that enterprises using proprietary AI models pay twice – in money and in the proprietary data they inadvertently feed to the models, which could eventually be used against them.
Microsoft CEO Satya Nadella has joined a growing chorus of tech leaders warning about the hidden costs of using proprietary AI models. In a blog post published Monday, he argues that AI users—whom he calls "buyers"—are paying twice: once for token usage and again, unknowingly, by handing over valuable business data.
"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," Nadella writes. He notes that every prompt, every tool use, and every correction to a model becomes distilled institutional know-how that a competitor could never buy.
Nadella points out the hypocrisy of model makers: they freely scrape the internet for training data while imposing restrictive terms on "distillation"—the practice of learning from a model's outputs. He specifically criticizes clauses that allow model makers to learn from customer usage data.
His proposed solution is typical of a cloud giant: companies should retain ownership of their data—including prompts and feedback—and build proprietary learning environments on the cloud (likely Azure). He also urges the creation of "orchestration layers" to switch between AI providers easily, avoiding vendor lock-in. Although Nadella never explicitly mentions open source, the subtext is clear.
Idit Levine, CEO of Solo.io, confirms the trend: her enterprise clients are increasingly moving to open source models deployed on-premises. "Can I take an open source model and run it on-prem? It will do almost 90% of what the big one's doing. It will cost way less," she told TechCrunch. Solo.io's technology powers the Linux Foundation's Agentgateway project, and its customers include T-Mobile, ADP, and SAP.
Data from Vercel and OpenRouter supports the shift: open models accounted for 29% of all traffic through Vercel's gateway last month. Nadella's warning could accelerate this movement. "In consuming intelligence, you are creating intelligence. And what you create should belong to you," he concludes.
