Satya Nadella has issued a shocking warning to companies using AI

The CEO of a major cloud provider has warned companies that using proprietary AI models from other companies creates a hidden cost: those model makers gain access to sensitive business information and can learn from customer data to potentially become competitors. The warning matters because it articulates a concern shared by venture capitalists and other tech leaders that AI model providers act like "Trojan horses," extracting valuable proprietary knowledge while companies pay only for token usage. The CEO's proposed solution is for companies to build their own AI environments on cloud infrastructure and use tools that allow switching between different AI providers, rather than being locked into single proprietary models. Some enterprises are already moving toward using open-source AI models that they can run on their own servers, which gives them more control and lower costs.
