Microsoft CEO: AI Models Should be Easily Swappable

1846 ET - Microsoft CEO Satya Nadella stresses the necessity of customers being able to swap between different artificial-intelligence models, both closed-weight and open-weight. The number of Microsoft customers who are building using multiple models has risen fivefold since the start of the year, he tells analysts on a call Wednesday. "You've got to keep your harness separate from the model," Nadella says. "That means any given model at any given time is swappable. You should and you can use frontier models. There's no reason not to, but you also can use multiple of them, right?" Microsoft has stakes in both OpenAI and Anthropic, but last week joined companies including Nvidia and Palantir in signing an open letter in support of open models.
