Xiaomi Launches Hunter Alpha, a 1-Trillion-Parameter AI Model

Share


On March 11, 2026, two new artificial intelligence models, Hunter Alpha and Healer Alpha, unexpectedly appeared on OpenRouter, a developer platform that routes queries to multiple AI systems. The listing was unusual because there was no official announcement or developer attribution, and the models were labeled as “stealth models.” One of the chatbots stated, “I only know my name, my parameter scale, and my context window length.”

Initial reports by Reuters linked Hunter Alpha to an upcoming release from Chinese AI startup DeepSeek, as speculation around DeepSeek V4 had been building. Media suggested that Hunter Alpha shared the same specifications as DeepSeek V4, expected in April, but it was later clarified that the model is not from DeepSeek.

Luo Fuli, head of Xiaomi’s AI division MiMo and a former DeepSeek researcher, revealed on X (formerly Twitter) that Hunter Alpha is an early internal test build of MiMo-V2-Pro. She described the release as a “quiet ambush,” explaining that the shift from chat-based AI to agent-based systems happened so quickly that even Xiaomi barely anticipated it. The stealth release was designed to gather unbiased feedback from users before the official announcement.

Hunter Alpha functions as the “brain” of an AI agent, enabling tools to perform complex tasks with minimal human intervention. It is a 1-trillion-parameter model with a context window of up to 1 million tokens, capable of processing and remembering massive amounts of text or documents in a single conversation.

Xiaomi plans to partner with five major agent frameworks, including OpenClaw, to provide free access to developers worldwide for a week. The company also intends to open-source the model once it reaches sufficient stability. Following the announcement, Xiaomi’s Hong Kong-listed shares surged by 5.8% on March 19, signaling the company’s growing pivot from smartphones and EVs to AI innovation, with Hunter Alpha leading the charge.
