Xiaomi rolled out MiMo-V2.6 in September 2026 as a three-model lineup — a trillion-parameter flagship (Pro), a low-cost workhorse (Flash), and a latency-tuned UltraSpeed variant — all omni-modal and available through its API and third-party providers.

Xiaomi has released the MiMo-V2.6 series, the latest step in the large-language-model family it launched in April 2025 with the reasoning-focused MiMo-7B. The V2.6 lineup is three distinct models rather than a single model: MiMo-V2.6-Pro, described by Xiaomi as its "most powerful flagship reasoning model — omni-modal, ultra-high performance, trillion-parameter," aimed at complex projects, long-horizon tasks, and research; MiMo-V2.6-Flash, a full-modality, lower-cost reasoning model built for high-frequency calls and large-scale workloads; and MiMo-V2.6-Pro-UltraSpeed, which Xiaomi says delivers flagship Pro-level performance up to 20x faster for real-time and latency-sensitive use.
"Omni-modal" is the theme across the series: the models are built to take in text, images, audio, and video rather than text alone, positioned by Xiaomi as flagship models "built for professional workflows." All three models share a roughly million-token context window (about 1,048,576 tokens), long enough to hold an entire book, a full 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.
The models are reachable through Xiaomi's own MiMo API platform and through third-party gateways such as OpenRouter — and, for two of the three, by downloading the weights directly. Xiaomi published both MiMo-V2.6-Pro and MiMo-V2.6-Flash as open weights on Hugging Face under an MIT license, permitting commercial use and self-hosting, including the trillion-parameter flagship. Only Pro-UltraSpeed, a hosted fast-serving mode built on the same Pro checkpoint, is API-only. Because the series just launched, treat exact per-model pricing and benchmark specifics as still settling — confirm the current details on Xiaomi's official MiMo pages before you rely on them.
A new omni-modal reasoning model is an upgrade to the *reading and thinking* step of a content workflow, not the *shipping* step — and the shipping step is where the week disappears. MiMo can reason over a long transcript or a video and hand you sharp raw material; it cannot turn that into captioned shorts, a brand-exact carousel, a face-consistent avatar video, a blog, and a newsletter, then schedule and publish them. [Kompozy](/) is the engine that does. On the Founding tier you can bring your own model key, so a fast, cheap reasoning model like MiMo can sit at the ingestion step while Kompozy runs everything downstream.
Here is the concrete move today. Feed one source — a long webinar, a research doc, a batch of calls — through the ingestion step, then let Kompozy fan it into finished formats governed by a single [Persona Brief](/glossary/persona-brief): captioned [Persona Shorts](/glossary/persona-shorts) and [Clipped Shorts](/glossary/clipped-short), brand-exact [Carousel Posts](/glossary/hyperframes), Photo Posts, Quote Graphics, a Blog Article, and an Email Newsletter. [Autopilot](/glossary/autopilot) then schedules and publishes the set across the eight social platforms plus blog and email, each piece clearing a per-post review gate first. The model got better at reasoning; Kompozy is what turns that reasoning into content your audience actually sees.
MiMo-V2.6 is the September 2026 release in Xiaomi's MiMo family of large language models. It is 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.
Largely, yes. Xiaomi published both MiMo-V2.6-Pro (the trillion-parameter flagship) and MiMo-V2.6-Flash as open weights on Hugging Face under an MIT license, permitting commercial use and self-hosting. Pro-UltraSpeed is a hosted fast-serving mode of the same Pro checkpoint rather than a separate downloadable model, so it remains API-only. Check Xiaomi's official MiMo pages for current status.
A model like MiMo is best at the ingestion and reasoning step — reading and summarizing long transcripts, PDFs, audio, or video and drafting raw material. It does not caption clips, build carousels, keep an avatar's face consistent, or publish. To turn that output into finished, on-brand posts across platforms, pair it with a content engine like Kompozy, which on its Founding tier lets you bring your own model key.
All three MiMo-V2.6 models — Pro, Flash, and Pro-UltraSpeed — carry a context window of roughly one million tokens (about 1,048,576), large enough to hold a full book, a long webinar transcript, or a sizable research corpus in a single prompt. Confirm the exact figure for each model on Xiaomi's official MiMo documentation.
