Ant Group has reduced AI training costs by 20% by utilizing Chinese-made semiconductors from Alibaba and Huawei instead of Nvidia chips. By adopting the Mixture of Experts machine learning method, Ant lowered its expenses for training 1 trillion tokens from 6.35 million yuan to 5.1 million yuan. This shift highlights the trend among China's leading companies to pursue self-sufficiency in technology in response to stricter U.S. export controls on advanced chips. Ant aims to enhance its AI services with new models and methods, reinforcing its commitment to self-reliance in the current climate.
