This documentation page explains how to download, quantize, and run Z.ai's GLM-5.3-Flash (ox-alpha) 320B multimodal model locally using Unsloth Desktop or llama.cpp. It provides hardware requirements, quantization comparisons, recommended inference settings, and instructions for serving the model as a local API.
This is most valuable when you need local or private LLM inference, want to prototype AI features without recurring API costs, or require a strong coding/agentic model on your own hardware. It is also useful when choosing the right quantization level for a specific memory budget.
