Xiaomi's September 2026 omni-modal reasoning series — a trillion-parameter flagship (Pro), a low-cost workhorse (Flash), and a latency-tuned UltraSpeed variant with a roughly million-token context, all reachable through a standard API.

Xiaomi MiMo-V2.6 is the September 2026 release in Xiaomi's MiMo family of large language models, which started in April 2025 with the reasoning-focused MiMo-7B. V2.6 is a three-model series, not a single model. MiMo-V2.6-Pro is Xiaomi's "most powerful flagship reasoning model — omni-modal, ultra-high performance, trillion-parameter," aimed at complex, long-horizon work. MiMo-V2.6-Flash is a full-modality, lower-cost model built for high-frequency calls and large-scale tasks. MiMo-V2.6-Pro-UltraSpeed delivers flagship-level performance up to 20x faster for real-time and latency-sensitive workloads.
The common thread is "omni-modal" input: the models are designed to read text, images, audio, and video rather than text alone. The UltraSpeed variant carries a context window of roughly one million tokens (about 1,048,576), enough to hold an entire book, a long webinar transcript, or a large research corpus in a single prompt. MiMo sits inside Xiaomi's broader "Human x Car x Home" AI strategy, and its reasoning work has been led by Luo Fuli, who joined Xiaomi from DeepSeek.
You reach MiMo-V2.6 through Xiaomi's own MiMo API platform and through third-party gateways such as OpenRouter, using a standard chat-completions interface with tool use and structured output. Licensing has been mixed across the family: some earlier and smaller MiMo models shipped as open weights under an MIT license on Hugging Face, while the trillion-parameter Pro tier has been offered via API rather than as downloadable weights. Because the series is new and still rolling out, treat exact per-model pricing, benchmark scores, open-weight availability, and the precise launch date as still settling — confirm the current details on Xiaomi's official MiMo pages before relying on them.
Think of MiMo-V2.6 as the reader in the room: hand it a two-hour webinar, a research folder, or a stack of customer calls and it will reason across the whole thing and hand back the sharpest ideas — because its omni-modal input and roughly million-token context let it hold the entire source at once. What it will not do is turn those ideas into content anyone sees. It writes tokens; it does not caption a clip, size a carousel to each platform, keep a persona's face consistent across images, or publish. [Kompozy](/) is the studio and the distribution that pick up exactly there.
The concrete pipeline: use MiMo to ingest and reason over the raw source, then bring that same source into Kompozy and set a [Persona Brief](/glossary/persona-brief) so voice, terminology, and banned words govern every output. From one input Kompozy generates the formats MiMo can't — [Clipped Shorts](/glossary/clipped-short) cut from the long video at its strongest moments, captioned [Persona Shorts](/glossary/persona-shorts) and brand-exact [Persona Frames](/glossary/persona-frames) fronted by a face-locked avatar, listicle-style concept video, brand-exact [Carousel Posts](/glossary/hyperframes), Photo Posts, Quote Graphics, a Blog Article, and an Email Newsletter. Then [Autopilot](/glossary/autopilot) schedules and publishes the whole set across the eight social platforms plus blog and email, each piece behind a per-post review gate. On Kompozy's Founding tier you can bring your own model key, so MiMo can literally run the ingestion step inside this workflow — the reader and the studio in one line.
It is the September 2026 release in Xiaomi's MiMo family of large language models — a three-model series: Pro (a trillion-parameter flagship reasoning model), Flash (a low-cost, full-modality model for high-frequency use), and Pro-UltraSpeed (flagship performance up to 20x faster). All three are omni-modal, taking in text, images, audio, and video.
Not directly. MiMo is a language model — it reasons and drafts text, and reads images, audio, and video, but it does not caption clips, build carousels, generate persona video, keep a face consistent, or publish. To turn its output into finished, scheduled posts across platforms, pair it with a content engine like Kompozy.
It is omni-modal, so it accepts text, images, audio, and video as input. That means a podcast episode or a screen recording can be a direct source without a separate transcription step, and its roughly million-token context (on the UltraSpeed variant) can hold a full transcript or a large document set in one prompt.
Use MiMo for the ingestion and reasoning step, then run the same source through Kompozy: set a Persona Brief for your voice, let it generate Clipped Shorts, persona/avatar video, carousels, photo posts, quote graphics, a blog, and a newsletter, and let Autopilot schedule and publish across the eight social platforms plus blog and email. On the Founding tier you can bring your own MiMo key to run that ingestion step inside Kompozy.
