The United States government has banned federal agencies from utilizing artificial intelligence (AI) tools developed by Chinese startup DeepSeek, escalating tensions in the global AI race. The Department of Homeland Security issued the directive on Monday, prohibiting the use of DeepSeek’s products and any third-party tools built upon its technology. This move reflects growing US concerns about national security risks associated with foreign-developed AI. The ban aims to protect sensitive government data and systems from potential vulnerabilities. It highlights the increasing scrutiny of Chinese technology firms operating in critical sectors within the US. As both countries compete for leadership in AI, further restrictions and protective measures are anticipated. This decision underscores the strategic importance of AI and the lengths to which the US is willing to go to maintain a competitive edge.
