Z.ai confirms: the “stealth model” Ox Alpha belongs to the GLM series, and its weights will be released

Z.ai has confirmed that the model code-named Ox Alpha belongs to its GLM lineup and is not some outside party's work. The model had previously surfaced as a “stealth” novelty — that is, it was released without any explicit attribution, which spawned speculation about its origins.

According to the announcement, Z.ai intends to open the weights of Ox Alpha. This means the model will move into the publicly available category: third-party developers will be able to download it, run it locally and fine-tune it, rather than merely using it through a closed interface. For the Chinese AI scene, such a step is very much in keeping with established practice — major players regularly release open models, competing with one another on, among other things, the quality of their public releases.

The very headline of the source material places Ox Alpha squarely alongside DeepSeek — another Chinese development that became a notable event on the market. This is about the rivalry within the rapidly growing segment of open language models, where Z.ai, with its GLM series, is trying to establish itself as one of the leading providers.

The details — including the model's exact specifications, the timeline for publishing the weights and the licensing terms — are not disclosed in the available portion of the material. For now, it is only a matter of confirming that Ox Alpha belongs to the GLM family and of the mere fact that the weights are about to be opened.
