February Explosion! China's AI Call Volume Surpasses the United States for the First Time, Four Major Models Dominate the Global Top Five, and Domestic Computing Power Demand is Experiencing Exponential Growth In February, the number of AI model calls in China exploded, surpassing that of the United States for the first time. According to OpenRouter, the world's largest AI model API aggregation platform, during the week of the 9th to the 15th, Chinese models exceeded the 2.94 trillion tokens of American models for the first time with 4.12 trillion tokens of calls. From the 16th to the 22nd of this week, the weekly call volume of Chinese models further surged to 5.16 trillion tokens, a 127% increase in three weeks, while the call volume of American models fell to 2.7 trillion tokens during the same period. At the same time, among the top five models in terms of global call volume, Chinese models occupy four seats. This strong growth momentum is not dependent on a single popular product, but on the cluster rise of Chinese AI manufacturers. (Daily Economic News)
