China's AI usage surpasses the United States for the first time, with four large models dominating the top five globally.

In February, the model invocation volume of Chinese AI has explosively increased, surpassing the United States for the first time. Data from OpenRouter, the world's largest AI model API aggregation platform, shows that from the 9th to the 15th of this month, Chinese models had a invocation volume of 4.12 trillion Tokens, exceeding the 2.94 trillion Tokens of the same period in the United States for the first time. From the 16th to the 22nd of this month, the weekly invocation volume of Chinese models further increased to 5.16 trillion Tokens, a 127% increase over the past three weeks, while the United States models' invocation volume dropped to 2.7 trillion Tokens. At the same time, among the top five models in global invocation volume rankings, Chinese models occupy four positions. This powerful growth momentum is not based on a single hot product, but rather on the cluster-like rise of Chinese AI companies. Token is the smallest unit for AI models to process text. Compared to the number of users, Token invocation volume is a key indicator that more accurately reflects the intensity of AI model usage, user stickiness, and commercial value. Chinese model manufacturers are seizing the global market with rapid iteration and cost advantages, and the demand for domestic computing power is experiencing exponential growth.
