Xiaomi released three new artificial intelligence models in mid-March 2026, MiMo-V2-Pro, MiMo-V2-Omni and MiMo-V2-TTS, without a launch event, and in doing so answered a question that had occupied developers for weeks. The company confirmed that MiMo-V2-Pro is the model that had been circulating anonymously on the OpenRouter platform under the name Hunter Alpha.
The release positions the smartphone and consumer electronics maker as a serious participant in China’s crowded frontier model race, alongside Alibaba, ByteDance, DeepSeek, Moonshot and Zhipu.
The three models
MiMo-V2-Pro is the flagship. According to Xiaomi and to reporting by The Decoder, it is a large mixture-of-experts model with roughly one trillion total parameters, built for agentic workloads such as multistep coding, tool use and long-running tasks, and it supports a context window of up to one million tokens. Xiaomi pitches it as competitive with leading proprietary models on coding and reasoning benchmarks while costing considerably less to run.
MiMo-V2-Omni is a multimodal model that accepts text, images, audio and video, intended for assistants and for the robotics and smart-device work that Xiaomi has been expanding. MiMo-V2-TTS is a text-to-speech model that the company says produces more natural, expressive voices and can control tone and emotion through instructions.
The Hunter Alpha reveal
For several weeks before the announcement, a model labeled Hunter Alpha had been available free of charge on OpenRouter, a service that routes requests to many AI models through a single interface. Developers noted strong coding performance and speculated that a major Western or Chinese lab was quietly testing an unreleased system. Xiaomi’s announcement confirmed the model was MiMo-V2-Pro in a pre-release form, a tactic several labs have used to collect real-world feedback before a formal launch.
A large bet by a hardware company
Xiaomi is better known for phones, home appliances and, since 2024, electric vehicles. Caixin reported that the company has committed tens of billions of yuan to AI research and that founder Lei Jun has framed the MiMo project as central to Xiaomi’s strategy of connecting its cars, phones and smart-home products through a single intelligent layer.
The company first published MiMo models in 2025 as relatively small open-weight releases. The V2 series marks a step up in scale and ambition, and the Pro model is being offered through Xiaomi’s own API as well as through third-party platforms.
Benchmark figures and cost comparisons cited at launch come from Xiaomi itself and have not yet been independently audited. Even so, the arrival of another Chinese lab with a trillion-parameter agentic model, priced aggressively, adds to pressure on established providers and underlines how quickly the field is broadening beyond a handful of American companies.
