Zhipu Confirms Ox Alpha is GLM-5.3-Flash, Releases Model Weights
Zhipu AI has identified the model previously known as Ox Alpha as its GLM-5.3-Flash, releasing the model weights. This release includes the first natively multimodal model in the GLM-5 series.
Zhipu AI has confirmed that the model tested anonymously as Ox Alpha is its GLM-5.3-Flash, a significant update to its generative language model series. The company announced the release of the model weights, making them available to the public.
The newly released GLM-5.3-Flash boasts 320 billion total parameters and 18 billion active parameters. This iteration marks a key advancement as it is the first natively multimodal model within the GLM-5 family. It is designed to process and understand various forms of data, including text, images, videos, and visual documents, supporting interleaved multimodal inputs.
Prior to its official release and confirmation, the model underwent anonymous evaluations on platforms like OpenRouter and OpenCode. These assessments aimed to gauge its performance and capabilities across different benchmarks. The availability of its weights on Hugging Face is expected to facilitate further research and development within the AI community.
This release positions Zhipu AI to compete in the rapidly evolving field of large multimodal models, which are increasingly seen as crucial for next-generation AI applications. The company's move to share model weights often encourages broader adoption and collaboration.
