# Chinese AI Models Now Dominate OpenRouter with 45% Traffic, Cost Arbitrage Driver

> A year ago, Chinese AI providers accounted for less than 2 percent of traffic on OpenRouter, a popular router that lets developers switch between models. Today they serve roughly 45 percent, with Xiaomi's MiMo-V2-Pro alone capturing about 21 percent of usage, well ahead of OpenAI's 7.5 percent. The driver is not ideology but arithmetic. Chinese models undercut Western rivals by anywhere from three to ten times on price, and many ship with very large context windows, making them attractive for high-volume, cost-sensitive workloads. When developers can route the same task to a model that costs a fraction as much, a lot of them do, quietly, at the API layer where end users never see the brand. The shift is a striking piece of evidence that the AI market is fragmenting along cost lines, not just capability. It also complicates the geopolitical picture: even as governments debate export controls and national frameworks, the actual flow of AI usage is already global, price-driven, and increasingly Chinese.
