Xiaomi unveils its MiMo-V2 AI models, including the 1T-parameter MiMo-V2-Pro, codenamed Hunter Alpha, which Xiaomi says benchmarks close to GPT-5.2 and Opus 4.6
Led by Fuli Luo, a veteran of the disruptive DeepSeek R1 project, the release represents what Luo characterizes as a “quiet ambush” on the global frontier.
The significance is less a verified ranking than a new contender making a concrete performance claim against named frontier systems. Fuli Luo’s DeepSeek R1 background makes the release part of a growing effort to turn reasoning-model expertise into a broader Xiaomi model portfolio.
First-order effects
Xiaomi gains a flagship 1T-parameter MiMo model, Hunter Alpha, to anchor its frontier-model positioning; the company’s comparisons to GPT-5.2 and Opus 4.6 will invite immediate independent evaluation.
Model buyers and developers considering MiMo now have a higher-stakes capability claim to test, while the reported evidence remains Xiaomi’s own benchmarking assertion.
Second-order effects
Rival model providers face another benchmark comparison point in reasoning, coding and agentic evaluations, increasing the value of transparent, task-specific tests over headline model size.
The release gives Xiaomi a stronger base for subsequent distribution choices, including the later MIT-licensed MiMo-V2.5 releases, which could widen developer access if comparable capabilities are carried forward.
Third-order effects
If Xiaomi can repeatedly pair frontier-scale claims with open or broadly accessible releases, model procurement may shift further toward multi-vendor evaluation rather than reliance on a small set of closed-model suppliers.
The larger structural test is whether benchmark parity can translate into dependable deployment performance; if it does, Chinese device and platform companies could become more consequential suppliers of general-purpose AI models.
The trend: Frontier AI competition is broadening from a handful of specialist labs to platform companies building model families, distribution channels and developer ecosystems together.
MiMo-V2-Pro & Omni & TTS is out. Our first full-stack model family built truly for the Agent era. I call this a quiet ambush — not because we planned it, but because the shift from Chat to Agent paradigm happened so fast, even we barely believed it. Somewhere in between was a
Xiaomi has released MiMo-V2-Pro, which scores 49 on the Artificial Analysis Intelligence Index, placing it between Kimi K2.5 and GLM-5 @Xiaomi's MiMo-V2-Pro is a new reasoning model and a significant upgrade over their prior open weights release, MiMo-V2-Flash (309B total / 15B […
The “genius girl” who previously worked at DeepSeek and was recruited by Lei Jun for Xiaomi AI is now on Twitter as well. It feels like more Chinese AI talent is realizing they can come here, speak for themselves, and build influence directly. I'm all for the added interaction
> MiMo-V2-Pro is more token efficient than peers They've previously shrunk token usage of MiMo-V2-Flash in Feb update. They want it to drive their ecosystem, not score on benches. ...Or reach AGI. What's up with CritPt? This looks like Hunter-Alpha: disappointing. [image]
Stealth Model Reveal: Hunter and Healer Alpha are @XiaomiMiMo MiMo-V2-Pro and MiMo-V2-Omni Both models are live now on OpenRouter, and free to use in @OpenClaw via the OpenRouter provider for the next week! [image]
MiniMax-M2.7 cost ~$175 to run the Artificial Analysis Intelligence Index at $0.30/$1.20 per 1M input/output tokens (unchanged from M2.5), making it less expensive than peer models at similar intelligence such as GLM-5 (Reasoning, ~$547), MiMo-V2-Pro (Reasoning, ~$348), and Kimi …
“So I gave a hard mandate: anyone on MiMo Team with fewer than 100 conversations tomorrow can quit. It worked. Once the team's imagination was ignited by what agentic systems could do, that imagination converted directly into research velocity.” Chinese AI leaders going hard
MiMo-V2-Pro scores 5 on the AA-Omniscience Index, driven primarily by a low hallucination rate of 30%. This is an improvement over MiMo-V2-Flash's 48% hallucination rate [image]

Xiaomi has officially released MiMo-V2-Pro, a massive reasoning upgrade over its previous open-weights MiMo-V2-Flash model. While the previous Flash version was open source, MiMo-V2-Pro is currently available exclusively via Xiaomi's first-party API. MiMo-V2-Pro scored a 49 on [i…
“treated inference as a first-class citizen from day one” is the most important line in this entire thread. the MIMO change trading training speed for inference utilization is exactly the right tradeoff for production deployment. removing the short conv is also underrated - its
Xiaomi just revealed that “Hunter Alpha” - the mystery model that topped OpenRouter's charts all week - is actually MiMo-V2-Pro. 1M context and 78.0 on SWE-bench (right next to Sonnet 4.6's 79.6) And we've partnered with the MiMo team to offer one week of free access in Cline! [i…

MiMo-V2-Pro by Xiaomi scored 49 on AAII, surpassing Kimi K2.5 and ranking just below GLM-5. To be honest, I'm not surprised at all, because MiMo's models have always been about benchmaxxing, and this time is definitely no exception. MiMo-V2-Pro is very likely the anonymous [image…
everyone's probably tired of how many models are available nowadays but i still have to say i've been using mimo-v2-pro all day and i completely forgot i was trying something new it's free right now in opencode if you want to try
MiMo-V2-Pro and MiMo-V2-Omni are now free in OpenCode many of you have tried them in stealth - Hunter Alpha and Healer Alpha. Mystery solved worth mentioning - MiMo-V2-Pro: - ~1T params - 1M context - optimized for coding
🚨 MiMo-V2-Pro by Xiaomi has suddenly appeared on Artificial Analysis before any official announcements. Mentioned as a proprietary unimodal (text-only) reasoning model, it sports a 1 million context window with an Intelligence Index score of 49, sitting just below GLM-5. [image]
