According to TechCrunch, Microsoft's President Brad Smith stated at a Senate hearing that due to data security and advertising content risks, Microsoft prohibits employees from using the DeepSeek application service and has not listed it in the app store. Although Microsoft previously offered the DeepSeek R1 model for download on Azure, it was limited to Open Source model deployment and not an official application. Smith also revealed that Microsoft had made "modifications" to the DeepSeek model to remove potentially harmful content.
