The quantization was produced at RadixArk using NVIDIA Model Optimizer, following an expert-only NVFP4 W4A4 recipe. **Run on SGLang**: launch command and per-platform recipes in the GLM-5.3 cookbook. This model is not owned or developed by RadixArk. It is a quantized derivative of Z.ai's model; see the upstream GLM-5.3 model card for the source model's capabilities, training information, limitations, and license.

Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
