Chinese AI company DeepSeek has postponed the launch of its R2 model after repeated technical problems using Huawei's Ascend processors for training. The delay highlights Beijing's ongoing struggle to replace US-made chips with domestic alternatives.
Authorities had encouraged DeepSeek to shift from Nvidia hardware to Huawei's chips after the release of its R1 model in January. However, training failures, slower inter-chip connections, stability issues, and weaker software performance led the start-up to revert to Nvidia chips for training, while continuing to explore Ascend for inference tasks.
Despite Huawei deploying engineers to assist on-site, DeepSeek was unable to complete a successful training run using Ascend processors. The company is also contending with extended data-labelling timelines for its updated model, adding to the delays.
The situation underscores how far Chinese chip technology lags behind Nvidia for advanced AI development, even as Beijing pressures domestic firms to use local products. Industry observers say Huawei is facing "growing pains" but could close the gap over time. Meanwhile, competitors like Alibaba's Qwen3 have integrated elements of DeepSeek's design more efficiently, intensifying market pressure.
