PANews reported on May 9 that according to TechCrunch, Microsoft President Brad Smith said at a Senate hearing that due to data security and publicity content risks, Microsoft banned employees from using DeepSeek application services and did not put it on the app store. Although Microsoft once provided DeepSeek R1 model downloads on Azure, it was limited to open source model deployment, not official applications. Smith also revealed that Microsoft had "modified" the DeepSeek model to remove potentially harmful content.
