Xiaomi's MiMo passes 1 trillion tokens, founder Lei Jun says it's a new milestone

Milestone announced

Xiaomi (小米) founder, chairman and CEO Lei Jun (雷军) announced on Weibo that the company's large language model family, MiMo, has surpassed 1 trillion tokens processed. The post framed the achievement as a new milestone for Xiaomi in the fast-moving field of foundation models. Short and to the point: Xiaomi is signaling the model is seeing serious real‑world use across developers and services.

Benchmarking and credibility

It has been reported that MiMo‑V2‑Pro recently climbed into the global top five on Text Arena's Model Rank for complex logical reasoning, long instruction following and multi‑turn dialogue. Text Arena, an influential benchmark in the AI community, says it uses a "double‑blind" testing method in which model identities are hidden and global users vote on answer quality in real time — a mechanism designed to limit dataset gaming. According to reports, Xiaomi also ranks highly on Text Arena's LabRank and Code Arena lists, placing the company among established Western rivals including Anthropic, OpenAI and Google.

Usage numbers and wider context

Xiaomi launched the MiMo‑V2 family globally on March 19, 2026, and the series — especially MiMo‑V2‑Pro/Omni — has drawn developer attention. It has been reported that on OpenRouter the MiMo‑V2‑Pro has topped daily, weekly and monthly call charts, and that OpenRouter's recent weekly token consumption recently exceeded 4 trillion tokens. Those figures, if sustained, point to rapidly growing adoption outside Xiaomi's traditional hardware business.

What this means geopolitically

Why does this matter beyond China? Because demonstrations of scale and competitive benchmarking feed directly into the global AI narrative — one in which U.S. export controls on advanced chips and other trade frictions shape how quickly Chinese firms can scale model training and inference. Xiaomi's claimed progress suggests Chinese companies are narrowing gaps on model quality and deployment, even as access to top‑end silicon and international partnerships remains constrained. The big question now: can usage and rankings convert into durable commercial leadership?
