Z.ai has made GLM-5.3-Flash available across its official platforms and released its weights on Hugging Face, according to CNET. The model was previously presented on OpenRouter as Ox Alpha and is described as built for coding, sustained agentic work, browser use and computer interaction. Z.ai's coding subscriptions start at $18 a month. The weights exceed 300GB, meaning local use may require substantial computing power.
