DeepSeek poses a challenge to Beijing as much as to Silicon Valley

With the release of its latest artificial-intelligence (AI) model, DeepSeek, an obscure Chinese firm, has laid waste to several years of American policy meant to hold back Chinese innovation—and, in the process, blown a hole in the valuations of companies from Nvidia, America’s AI chip champion, to Siemens Energy, a manufacturer of electrical equipment used in data centres (see previous article). In demonstrating its ability to innovate around American export restrictions, DeepSeek has raised doubts as to whether access to piles of cutting-edge semiconductors and related equipment is as important as previously thought when it comes to training AI models.
