OpenRouter launches two anonymous Stealth models, and the community speculates they may be new products from Zhipu, DeepSeek, or Kimi.

Gate News, March 12 — The model routing platform OpenRouter has launched two new Stealth anonymous models today, with providers not publicly disclosed. Both are available for free. Hunter Alpha is a 10 trillion parameter pure text model with a context window of 1 million tokens, designed for long-term planning, complex reasoning, and multi-step task scenarios. Healer Alpha is a multimodal model that natively supports visual and audio inputs, with a context window of 262,144 tokens.

This follows the launch of Pony Alpha in February this year, with OpenRouter once again releasing anonymous models in the same manner. Pony Alpha at the time sparked similar speculation about its identity, which was eventually confirmed to be Zhipu GLM-5. Since both models come from the same anonymous provider, some in the community speculate that they are Zhipu’s new flagship model and visual language model. Another theory suggests that Hunter Alpha is DeepSeek V4 (based on the 1T parameters and 1 million context window, matching previous rumors), and Healer Alpha is Kimi K3 (based on the 262,144 context window matching Kimi K2.5). No official confirmation has been provided yet.
