New legislation in Congress would block Chinese artificial intelligence systems from federal agencies. It was introduced Wednesday as a bipartisan group of lawmakers pledged to ensure that the United States would prevail against China in the global competition over AI. And the House Select Committee on China held a hearing on the matter. About five months ago, a Chinese technology startup called DeepSeek introduced an AI model that rivaled platforms from OpenAI in performance, but cost only a fraction to build. This raised concerns that China was catching up to U.S. despite trade restrictions.
