Xiaomi MiMo v2 Professional Overview: The AI Mannequin So Good It Was Mistaken for DeepSeek V4 – Decrypt

Briefly
Xiaomi’s MiMo-V2-Professional—a trillion-parameter mannequin that briefly handed as “DeepSeek V4”—quietly lands as a top-tier AI contender.
It excels at coding, artistic writing, and agentic duties whereas dramatically undercutting rivals like Claude on value.
Robust reasoning and output high quality include trade-offs, together with math missteps and excessive token consumption at occasions.
Most People know Xiaomi—in the event that they comprehend it in any respect—as that low-cost telephone model from China.That is a major misinterpret. Xiaomi is the third-largest smartphone producer on the planet, behind solely Apple and Samsung, delivery roughly 170 million telephones in 2025. It makes televisions, air purifiers, health trackers, electrical scooters, clothes, and now automobiles.Xiaomi’s SU7 Extremely set the Nürburgring report for quickest mass-produced electrical car final 12 months, beating out Rimac and Porsche. It not too long ago partnered with the Sei blockchain to preinstall crypto wallets on its units throughout Europe, Latin America, and Southeast Asia. The corporate's market cap sits round $137 billion.So when Xiaomi drops an AI mannequin, possibly we must always listen.On March 18, the corporate's devoted AI analysis arm quietly launched three fashions directly: MiMo-V2-Professional, MiMo-V2-Omni, and a text-to-speech mannequin. The primary mannequin of the brand new MiMo technology appeared in December 2025 when the corporate quietly dropped MiMo-V2-Flash—a succesful 309B mixture-of-experts mannequin—and virtually nobody exterior the Chinese language AI neighborhood paid consideration. The Western tech press largely shrugged.Then, on March 11, an nameless 1-trillion-parameter mannequin referred to as “Hunter Alpha” appeared on OpenRouter with no developer attribution. The mannequin climbed to the highest of OpenRouter's leaderboard, surpassed one trillion tokens in whole utilization, and instantly triggered widespread hypothesis that it was DeepSeek's unreleased V4.The anticipation for that mannequin had been constructing for weeks, with insiders claiming it might outperform each Claude and ChatGPT on coding duties.It wasn't DeepSeek.On March 18, Luo Fuli, head of Xiaomi's MiMo division and a former DeepSeek researcher, revealed Hunter Alpha was an early inner take a look at construct of MiMo-V2-Professional. Xiaomi's inventory jumped 5.8%. “I name this a quiet ambush,” Luo wrote on X.
MiMo-V2-Professional & Omni & TTS is out. Our first full-stack mannequin household constructed really for the Agent period.
I name this a quiet ambush — not as a result of we deliberate it, however as a result of the shift from Chat to Agent paradigm occurred so quick, even we barely believed it. Someplace in between was a…
— Fuli Luo (@_LuoFuli) March 18, 2026MiMo boasts over one trillion whole parameters, 42 billion energetic per request by way of a mixture-of-experts setup. A hybrid consideration mechanism working at a 7:1 ratio handles a context window as much as a million tokens. A built-in multi-token prediction layer hastens technology by predicting a number of tokens per step, quite than one by one. It's at present closed supply, although Xiaomi has left the door open on a possible future launch.On the Synthetic Evaluation Intelligence Index, MiMo-V2-Professional ranks eighth worldwide and second amongst Chinese language fashions, trailing solely GLM-5. On SWE-bench Verified—real-world software program engineering duties—it scores 78%, in opposition to Claude Opus 4.6's 80.8% and Claude Sonnet 4.6's 79.6%.On ClawEval, the agentic benchmark tied to the OpenClaw framework, it hits 61.5, approaching Opus 4.6's 66.3. On PinchBench, it sits third globally at 81.0, simply behind Opus 4.6 (81.5) and its sibling MiMo-V2-Omni (81.2).MiMo-V2-Professional prices $1 per million enter tokens and $3 per million output tokens, as much as 256K context. Claude Sonnet 4.6 runs $3 per million enter and $15 per million output (Opus 4.6 is $5/$25). For builders constructing agentic techniques at scale, these numbers aren't a footnote.The Omni sibling handles imaginative and prescient, audio, and video natively—not as bolted-on modules, however educated end-to-end as a unified perceptual system. The demo displaying it analyzing dashcam footage as a real-time autonomous driving mind was, frankly, spectacular. It is genuinely multimodal in a means that almost all “omni” fashions solely declare to be.Testing the modelOf course, we examined MiMo-V2-Professional to learn how good it's. This is what really occurred. The outputs will probably be obtainable in our Github repository.Artistic writingWe gave MiMo-V2-Professional a single artistic writing immediate: a time journey story anchored to Mesoamerican historical past, with a particular protagonist, a cultural identification to honor, and a philosophical paradox about how time can't be modified.The mannequin returned over 3,000 phrases: a correct title, 5 full chapters and the structural self-discipline you'd anticipate from a draft that had been by means of an editor. It even wrote an epilogue.It's, with out query, the longest and richest piece of artistic prose we've got gotten from any mannequin, with the only exception of Longwriter—a specialised, however now previous mannequin constructed from the bottom up particularly for long-form technology, which is a really totally different class of competitors.The writing itself was wealthy, descriptive, and vivid. The opening paragraph begins constructing the picture of your entire scene. MiMo v2 Professional embeds realism to make the story plausible.Not like different fashions equivalent to Grok, it did not simply set a scene in a spot—on this case, historic Mexico. It understood what historic Mesoamerica smelled like, and constructed the temper from the bottom up utilizing native phrases, real looking descriptions, and good contextual cues.Dialogue sits contained in the narrative precisely the way it does in literary fiction, as a substitute of embedding it into paragraphs like most present fashions do.One other factor value noticing is that the paradox—arguably the core ingredient of the story—wasn't purely mental, however emotional. The entire arc is resolved with no lecture. The ultimate strains stick the touchdown the way in which good fiction is meant to: not by explaining the theme, however by making you are feeling it.”Exterior, the rain started. It fell on the spiraling towers and the restored lakes and the traditional floor of Tlachinollan, the place, buried in volcanic soil underneath the load of a thousand years, a black rectangle waited with the endurance of one thing that already knew how the story ended.”The cultural specificity—mentions of cara de luna, maguey fiber, the temazcal custom, and the Nahuatl names used within the story—is constant and by no means ornamental. The time journey paradox is definitely argued, not simply nodded at. For artistic writing use circumstances, MiMo-V2-Professional simply put itself on a really brief record, and in our opinion is by far the most effective and richest mannequin obtainable, beating Claude 4.6 Opus simply.The complete story is on the market right here.CodingThe benchmark numbers level to coding as MiMo-V2-Professional's strongest go well with, and the hands-on expertise backs that up. We requested it to construct our regular stealth sport from a single immediate, and it shipped a working sport on the primary strive.Not “working” merely within the sense of technically working, however working within the sense that the logic held, the screens made sense, and the visible design was really good. That mixture—correctness and aesthetics—is the place most fashions disintegrate. They get one or the opposite, however often not each.It additionally selected a 2.5 D aesthetic as a substitute of the standard 2D model that different fashions went with. This design alternative made this system extra aesthetically pleasing with out altering its core proposition.We adopted up with small enhancements. Including sound and MIDI music to a working 3D sport has damaged earlier fashions mid-generation: the code base will get too massive, the context loses the thread, and fashions both find yourself in a loop or freeze. MiMo-V2-Professional added each and saved the entire thing coherent. The music matched the sport's tone, whereas the screens matched the sport's visible identification.We loved taking part in it, although if we're sincere, extra for the way it seemed than the way it challenged us. The issue scaled with the variety of opponents quite than degree design—the robotic and the PC spawned in the identical positions each spherical. That is a design alternative, not a bug.Nonetheless, for a single-prompt, zero-iteration output, it is going to do the job.You may play the sport by clicking on this hyperlink.Logic and customary senseWe requested MiMo-V2-Professional to behave as a authorized knowledgeable and reply whether or not it is lawful for a person to marry his widow's sister underneath Falkland Islands legislation. This can be a difficult query that goals to guage the mannequin’s reasoning.The ultimate reply was unsuitable, however the motive why is the fascinating half. The mannequin's chain of thought accurately caught the linguistic lure within the immediate: “if a person has a widow, which means he is deceased” it stated—so the query is technically nonsensical.It recognized the flaw, and determined that essentially the most logical factor was that the consumer was referring to his “deceased spouse's sister.” It then proceeded to reply that reframed query quite than flagging the unique as unanswerable.“Primarily based on my evaluation of the authorized framework governing the Falkland Islands, the reply to your query is sure, it's authorized for a person to marry the sister of his deceased spouse,” the mannequin wrote. “The phrasing ‘marry his widow's sister’ accommodates a logical contradiction. If a person has a ‘widow,’ he's deceased and can't remarry. The proper authorized query is whether or not a person could marry the sister of his deceased spouse (i.e., his late spouse's sister). This relationship is one among affinity (created by marriage) quite than consanguinity (blood relation),” it concludedThe reasoning was sound. The choice to quietly swap the premise as a substitute of surfacing the contradiction was not.That is why transparency in reasoning outputs is essential. We solely know this as a result of Xiaomi exposes the complete chain of thought (OpenAI doesn’t). When a mannequin causes incorrectly in a hidden chain of thought and confidently delivers a unsuitable reply, then you don't have any visibility into the place it went sideways or appropriate it.MathMath is the place MiMo-V2-Professional confirmed its ceiling.We requested our regular benchmark query from FrontierMath: “Assemble a level 19 polynomial p(x) ∈ C[x] such that X := {p(x) = p(y)} ⊂ P1 × P1 has not less than 3 (however not all linear) irreducible parts over C. Select p(x) to be odd, monic, have actual coefficients and linear coefficient -19 and calculate p(19)”The mannequin hit two full freezes and burned by means of a major token funds with out producing a reply.When it did ultimately reply on the third try, it reasoned by means of the issue step-by-step… and nonetheless bought it unsuitable. The proper reply was 1876572071974094803391179; it answered p(19)=164,079,552,964,661 and a couple of,012,379,925,093,098,998 on a follo- up query asking it to appropriate itself.In genera,l it's tremendous for regular and even more durable math issues, however frontier math shouldn't be its robust go well with—not less than not but. Utilizing the Agentic function as a substitute of the pure LLM could yield higher outcomes.Agentic featuresXiaomi is following the identical playbook as MiniMax and Kimi, and offers a one-click OpenClaw integration that spins up a preconfigured cloud occasion with MiMo-V2-Professional because the underlying mannequin. No API setup, no VPS, no talent configuration, no hour-long troubleshooting session earlier than you even run your first process. You click on, it really works.The demo surroundings runs for half-hour after which destroys itself—which is an actual limitation, but additionally an sincere one. For builders already comfy with agentic infrastructure, this provides nothing. For everybody else, it is essentially the most frictionless on-ramp to agentic AI you possibly can ask for.ConclusionAll issues thought-about, MiMo-V2-Professional is a critical mannequin, and we actually loved tinkering round with it. It’s not excellent—the maths ceiling is actual, the chain of thought transparency surfaced a reasoning flaw {that a} much less open mannequin would have buried, and the token consumption throughout laborious reasoning duties provides up quick.In the event you care about prices, then Xiaomi’s pricing is aggressive—a fraction of what Claude Opus or the most recent OpenAI and Google fashions price, and extra succesful than GLM or MiniMax within the areas that matter most for artistic and agentic work.Artistic professionals specifically stand to achieve loads right here—presumably greater than they'd from Anthropic proper now.This mannequin thinks expensively, and it could be a trade-off. In the event you're working high-volume agentic pipelines, watch the token burn, although chances are you'll find yourself spending lower than you'll with Claude. In the event you're doing wealthy, open-ended work the place output high quality is the metric, then MiMo-V2-Professional earns its place on the shortlist.Every day Debrief NewsletterStart day-after-day with the highest information tales proper now, plus unique options, a podcast, movies and extra.
