DeepSeek's highly anticipated V4 large language model faced a delay, attributed to the company's deeper integration with China's domestic chip ecosystem. According to reports on May 25, 2026, DeepSeek spent multiple months optimizing its entire software stack for Huawei Technologies Co's Ascend chips. This work went far beyond basic compatibility—engineers performed hardware-specific tuning to maximize performance on the Ascend architecture, essentially treating the chip as a first-class citizen in their training and inference pipeline.
The full adaptation was completed in April 2026, after which DeepSeek resumed V4's rollout timeline. The strategic shift underscores China's broader push for AI infrastructure independence, aiming to reduce dependence on overseas chip suppliers such as Nvidia. By deeply integrating with Huawei's Ascend lineup, DeepSeek not only secures its supply chain but also gains potential performance advantages from tightly coupled hardware-software co-design. This move may set a precedent for other Chinese AI firms facing similar geopolitical pressures.
- DeepSeek delayed V4 to fully adapt its software stack to Huawei Ascend chips, completed April 2026.
- Optimization went beyond basic compatibility to hardware-specific tuning for better performance.
- The move signals China's accelerated push for AI infrastructure independence from overseas chip suppliers.
