Xiaomi's Stealth 1-Trillion-Parameter Hunter Alpha Revealed as MiMo-V2-Pro

TL;DR: Xiaomi's MiMo-V2-Pro, a 1-trillion-parameter model that appeared anonymously on OpenRouter as 'Hunter Alpha,' has been officially revealed. Built by former DeepSeek researcher Luo Fuli, the model surpassed 1 trillion tokens in usage during its stealth phase, topped OpenRouter's usage charts, and benchmarks near GPT-5.2 and Claude Opus 4.6 performance -- at roughly 1/6th the cost. Xiaomi plans to open source a variant when stable.

Why it matters: A consumer hardware giant entering the frontier AI race with a trillion-parameter open-weight model signals the competitive landscape is broadening well beyond traditional AI labs.
