CHINA’S AI FIRMS ARE CLEVERLY INNOVATING AROUND CHIP BANS


TWEAKS TO SOFTWARE BLUNT THE SHORTAGE OF POWERFUL HARDWARE

TODAY’S TOP artificial-intelligence (AI) models rely on large numbers of
cutting-edge processors known as graphics processing units (GPUs). Most Western
companies have no trouble acquiring them. Llama 3, the newest model from Meta, a
social-media giant, was trained on 16,000 H100 GPUs from Nvidia, an American
chipmaker. Meta plans to stockpile 600,000 more before year’s end. XAI, a
startup backed by Elon Musk, has built a data centre in Memphis powered by
100,000 H100s. And though OpenAI, the other big model-maker, is tight-lipped
about its GPU stash, it had its latest processors hand-delivered by Jensen
Huang, Nvidia’s boss, in April.
