China’s top AI is still trained on Nvidia chips. What is delaying a switch to local tech?

China’s most advanced artificial intelligence models are still being trained on Nvidia chips, sources at major Chinese large language model (LLM) developers say, as the prohibitively high cost of switching to local semiconductors continues to hamper Beijing’s push for self-sufficiency. While domestic hardware continues to advance, changing chip architecture presents a steep engineering bottleneck. “Training LLMs on Nvidia chips for now remains the norm among Chinese AI developers,” said a person...
