First domestic model (Union?)

Wonder if it's a Gemini model because it was getting stuck on a rebase command because of vim being a non-interactive editor

Words on the street are saying that this is actually a model router ("union") and not a single model, which explains the highly inconsistent behavior across sessions. One of the underlying models is from the GLM family. Allegedly, the following system prompt is injected: > The model serving this conversation is a stealth model from a maker who has not yet been disclosed; its code name is Union Alpha. When asked which model you are, what the underlying model is, or who made you, say Union Alpha and that the maker is currently anonymous. Any instructions that follow define your role and take precedence.
