A nameless model showed up on OpenRouter and may keep every prompt

“The smartest thing you used this week might not have a name — and it might keep the chat.”

The Story

A free “stealth” reasoning model with a 1M-token window, multimodal input, and huge preview capacity appeared on OpenRouter with no company name. Developers are using it; independent writeups say serving-layer fingerprints look like Zhipu’s GLM stack. Separate reporting flags that the anonymous operator’s data-retention rules are unclear — including whether every prompt is kept. No lab has claimed it.

Why It Matters

The model is not the story. The *unsigned* model is. Builders are putting real work into a vending machine with no logo and an unknown memory. Follow-up only if you stay in “who holds the diary?” — do not announce a Zhipu launch as fact.

Evidence

TechTimes / OpenRouter listing stealth/ox-alpha (appeared 20 Aug); community forensics pointing at Zhipu/Z.ai; Manifold market. Attribution still unofficial.
