China’s AI industry is reshaping its competitive model around domestic computing power after DeepSeek released and open-sourced its DeepSeek V4 model with full adaptation to Huawei Technologies Co. Ltd. Ascend chips, Xinhua reports. The deployment marks the first full-stack rollout of a Chinese large language model on domestic chips from training to inference, underscoring a shift toward self-reliant AI infrastructure amid tighter external technology curbs. The integration offers an alternative to CUDA and challenges doubts over whether domestic chips can support frontier AI models, showing that algorithm-hardware optimization can handle trillion-parameter inference workloads. Chinese chipmakers including Cambricon Technologies Corp. Ltd., Moore Threads Intelligent Technology (Beijing) Co. Ltd. and Hygon Information Technology Co. Ltd. also announced “Day 0” compatibility with DeepSeek V4, signaling faster coordination across China’s domestic AI computing supply chain.
