For most of 2025, US-developed AI models were the undisputed kings of OpenRouter, the model aggregation platform that lets developers route API calls across dozens of AI systems. They commanded nearly 70% of top-model usage share. That era is over.
Chinese AI models have not just caught up. They’ve lapped the competition, processing roughly 18 trillion tokens per week on the platform compared to about 5.5 trillion for US models. That’s a greater than 3-to-1 ratio, and the gap keeps widening.
The crossover point and what followed
The inflection point arrived during the week of February 9-15, 2026. That week, Chinese models processed 4.12 trillion tokens on OpenRouter, edging past the 2.94 trillion handled by US models. It was the first time Chinese systems outpaced American ones on the platform.
The platform’s total weekly volume has ballooned to over 25 trillion tokens, up from around 5 trillion just six months prior. Most of that explosive growth has been absorbed by Chinese models, not American ones.
