Zhipu confirms Ox Alpha as a new GLM model version, with weights set to open-source tonight

Zhipu has confirmed that Ox Alpha is a new version in its GLM model family and said the model weights will be released publicly tonight. The confirmation follows earlier community speculation that linked the model to Zhipu through clues such as API error messages and tokenizer behavior. Ox Alpha appeared anonymously on OpenRouter over the weekend, where it was positioned for coding and long-running agent tasks while also accepting text, image, and video inputs. According to the information cited by BlockBeats, the model quickly climbed to the top of OpenRouter by usage after launch, with usage already more than double that of DeepSeek. OpenRouter described the launch as the largest model release in the platform’s history. The model also marks a notable product change for Zhipu: unlike earlier GLM and GLM-V releases that separated core language and vision capabilities, Ox Alpha has been identified as a GLM model that can directly process both images and video. Ox Alpha will remain free for another week, while post-trial pricing has not been disclosed.
