Overview
- Xiaomi’s MiMo team, led by former DeepSeek researcher Luo Fuli, identified Hunter Alpha as an early internal test build of MiMo‑V2‑Pro intended to serve as the brain for AI agents.
- Hunter Alpha first appeared on OpenRouter on March 11 as a free, anonymous “stealth model,” prompting unconfirmed DeepSeek‑V4 chatter that was put to rest by Xiaomi’s disclosure.
- The model’s profile advertises roughly one trillion parameters and a context window of up to one million tokens, aligning with frontier large‑context, reasoning‑focused systems.
- MiMo said Hunter Alpha topped OpenRouter leaderboards and surpassed one trillion tokens in total usage, while earlier OpenRouter statistics had shown more than 160 billion tokens soon after launch.
- Following the reveal, Xiaomi’s Hong Kong‑listed shares rose as much as 5.8%, and MiMo said it will integrate the model with major agent frameworks such as OpenClaw with a week of free access for developers.
