Microsoft CEO Nadella warned in a CNN podcast that relying on a single AI model risks companies outsourcing their knowledge and thinking capabilities to the provider, losing independence. He agreed with Fareed Zakaria that each AI use feeds data and insights to vendors, who use them to improve their own models. He stressed that company generated token capital (knowledge from AI usage such as prompt context and interaction records) must stay internal, not be traded for free services. Nadella said any AI model can fail, so companies should control their own operations rather than relying on one provider, which would equal outsourcing their core functions. This aligns with Microsoft’s strategy of aggregating multiple models to support enterprise AI autonomy and avoid vendor lock-in, a key focus for companies competing for business clients.
