Seven months after stunning the world, China’s DeepSeek AI leans on US technology for critical upgrade

China’s Revolutionary DeepSeek Turns to American Hardware for Upgrade- China’s much-hyped DeepSeek project, once touted as a breakthrough in homegrown AI independence, has quietly circled back to American hardware after its gamble on Huawei’s Ascend chips fell short.

Engineers found the Chinese processors too unstable for large-scale training of the company’s new R2 model, forcing DeepSeek to rely again on Nvidia GPUs — the very technology U.S. export rules were meant to keep out of Beijing’s reach.
