OpenRouter data released on July 27th reveals a significant shift in the global artificial intelligence landscape, with Chinese large language models now accounting for the majority of worldwide usage. The data shows that Chinese models collectively hold approximately 63.5% of the global market share over the last 28 days, compared to just 35.5% for American models, widening the gap to roughly two-thirds of the total market.

Leading this surge is Xiaomi Corp.'s MiMo-V2.5, which has topped both the weekly and monthly charts for global model call volume on the OpenRouter platform. It was the only model in the world to surpass 10 trillion tokens in weekly call volume, and its monthly call volume reached 31.20 trillion tokens, outpacing the DeepSeek V4Flash's 23.58 trillion tokens. This performance indicates widespread adoption by global developers.

The top five models by monthly call volume on OpenRouter for July are all from China: Xiaomi Corp.'s MiMo-V2.5 in first place, followed by DeepSeek V4Flash, Tencent's HY3, Zhipu AI's GLM-5.2, and DeepSeek V4Pro. OpenRouter previously disclosed that the combined market share of Chinese models surpassed that of American models in early June, a trend that has since accelerated.

The MiMo-V2.5 is positioned as a foundational model for the Agent era, supporting a 1 million token context window and multimodal understanding covering text, images, video, and audio. Its coding and agent capabilities are recognized as being in the world's top tier. Since May, the global call volume for MiMo-V2.5 has grown steadily, rising from 1.46 trillion tokens per week to 10.46 trillion, representing an approximate 616% increase over two months. This makes it a representative example of the sustained growth in international usage for Chinese large language models.
