The free model, called Hunter Alpha, surfaced on the AI gateway platform OpenRouter on March 11 without any developer attribution and was later described by the platform as a “stealth model.”

During tests conducted by Reuters, the ‌Hunter Alpha chatbot described itself as “a Chinese AI model primarily trained in Chinese” and said its training data extended to May 2025, the same knowledge cutoff point reported by DeepSeek’s own chatbot.

When asked about its creator, however, the system declined to identify its developer.

“I only know my name, my parameter scale and my context window length,” the chatbot said.

Neither DeepSeek nor OpenRouter has identified the model’s creator and they did not respond to requests for comment.

Hunter Alpha’s profile page describes it as a 1-trillion-parameter model, meaning it was trained using roughly one trillion adjustable values that determine how the system processes language ⁠and generates responses. Models with more parameters generally require significantly more computing power to operate. The system also advertises 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.
