DeepSeek Grants Chinese Chipmakers Early Optimization Access

DeepSeek, the Chinese AI lab, excluded U.S. chipmakers Nvidia and AMD from previewing its upcoming flagship model V4 ahead of an expected Lunar New Year release, instead granting early optimization access to domestic suppliers including Huawei, two sources told Reuters. A U.S. official said the model was trained on Nvidia's Blackwell chips in China, raising potential export-control concerns.
