Z.ai confirms Ox Alpha is a new GLM-series model and will release its weights

Z.ai has claimed the previously anonymous Ox Alpha model, confirmed it belongs to the GLM series, and announced plans to open-source its weights. Ox Alpha scored close to DeepSeek on several benchmarks, but the company hasn't disclosed parameter count, training data, or a release date. The post doesn't spell out technical details or the license yet.

Why it matters: Z.ai claims the stealth Ox Alpha model, confirms it's GLM-series and will open weights. Bloomberg exclusive adds authority. Downside: no param count, training data, or timeline — still a teaser.
