Microsoft CEO Satya Nadella has warned that companies could lose control of their institutional knowledge if they depend entirely on proprietary AI providers. Companies Should Retain Their AI MetadataNadella said businesses should preserve the information generated whenever employees or software agents interact with an AI model. Without it, the model provider may gain valuable insight into the organisation’s internal processes while the customer remains dependent on the provider’s technology. Microsoft has been promoting this architecture through Microsoft Foundry’s model router, which selects between multiple models, and its AI Gateway, which sits between company applications and model providers. The concern resembles a warning investor Jason Calacanis gave after OpenAI offered AI credits to Y Combinator startups.
