US Lead in AI Over China Narrows After DeepSeek Gains, BI Says
American AI companies’ performance lead over China narrowed sharply in past months to a record low after labs such as DeepSeek gained ground, threatening US tech supremacy, according to Bloomberg Intelligence.
Top Chinese models lag their US rivals by just 3% on benchmark scores after the September release of DeepSeek’s V4.1 Flash, BI senior analyst Robert Lea wrote in a report Monday. That’s down from about 9% in May and 15% earlier in the year. That improving performance spells further market share gains for Chinese contenders, he said.
