When Call Volume Becomes 'Number One,' Would You Dare Write Your Paper That Way?

OpenRouter's global call volume ranking for last week (July 20-26): Xiaomi MiMo-V2.5 took first place with approximately 120 million calls, DeepSeek V4 Flash came second with about 98 million, Tencent HY3 third with around 75 million, Zhipu GLM-4 fourth with roughly 62 million, and ByteDance Doubao fifth with about 51 million. This list surprised many people because Xiaomi isn't a traditional large model player, yet its model grabbed the "global number one" spot.
