Xiaomi Confirms Mysterious Hunter Alpha AI Model as MiMo-V2-Pro

A powerful artificial intelligence model that appeared anonymously on a developer platform last week was revealed to be from Chinese smartphone and electric vehicle giant Xiaomi. The model, named Hunter Alpha, had fuelled speculation that startup DeepSeek was quietly testing its next-generation system ahead of a launch.
Xiaomi’s AI model team MiMo confirmed Hunter Alpha was an “early internal test build of MiMo-V2-Pro,” a flagship model. MiMo-V2-Pro is designed to serve as the “brain” of AI agents, tools that enable users to execute complex tasks with fewer human prompts and supervision than a chatbot.
MiMo is run by former DeepSeek researcher Luo Fuli. The release of DeepSeek’s low-cost models, DeepSeek-V3 and R1, triggered a global tech stock selloff last year, causing investors to question the expenditure of billions of dollars on AI computing power.
Since then, there has been significant interest in DeepSeek-V4, a next-generation model that has not yet been released. The mysterious free model, Hunter Alpha, surfaced on the AI gateway platform OpenRouter without any developer attribution.
Xiaomi’s new model release coincides with the rapid adoption of OpenClaw, an open-source agent framework, by users in China. Luo described the situation as a “quiet ambush,” noting the swift shift from a chat to an agent paradigm.
Luo added that she saw this rapid shift firsthand while building DeepSeek R1. MiMo-V2-Pro will partner with five major agent frameworks, including OpenClaw, to offer a week of free access to developers worldwide.
During tests conducted last week, the Hunter Alpha chatbot described itself as “a Chinese AI model primarily trained in Chinese,” and said its data extended back to May 2025. This knowledge cutoff point was also reported by DeepSeek’s own chatbot.
When asked about its creator, however, the system declined to identify its developer. The chatbot stated it only knew its name, parameter scale, and context window length.
Hunter Alpha’s profile page on OpenRouter described it as a 1-trillion-parameter model, meaning it was trained using roughly one trillion adjustable values. These values determine how the system processes language and generates responses.
The system also advertised a context window of up to one million tokens, a measure of how much text an AI model can process or remember during a single interaction. A token roughly corresponds to a short piece of text, such as part of a word.
Engineer Nabil Haouam, who builds AI agent systems, highlighted the combination of Hunter Alpha’s 1-million-token context, its reasoning capability, and free access. Haouam noted that most frontier models with that context window typically come with real cost at scale.
These specifications resembled expectations in local media for DeepSeek’s next-generation V4 model, which Chinese outlets have reported could launch as early as April. Umur Ozkul, who runs independent AI benchmark tests, said speculation connecting the model to DeepSeek was understandable given the timing and advertised capabilities.
Stealth model launches are not unusual, as platforms like OpenRouter allow developers to send queries to dozens of AI models through a single interface, making them a popular testing ground for new systems. An anonymous model called Pony Alpha appeared on OpenRouter in February before Chinese firm Zhipu AI confirmed it was part of its GLM-5 system five days later.
A notice on Hunter Alpha’s profile page indicated that all prompts and completions for the model are logged by the provider and may be used to improve the model. This underscores the industry-wide practice of using stealth model launches for unbiased feedback.
The model was adopted rapidly after appearing on the platform, surpassing one trillion tokens in total usage. It also topped the leaderboard charts on OpenRouter, according to MiMo. Xiaomi’s Hong Kong-listed shares surged as much as 5.8% on Thursday.
