GLM-5.3 is a mixture-of-experts model with 744B total parameters, of which 40B are active for each token. The model takes text input. The weights are released under the GLM-5.3 License. Commercial use is allowed with conditions. Model-as-a-service operators with group revenue above US$10 billion over 12 months must pass a security review by Z.ai before commercial use.
The official weights on Hugging Face take about 755 GB in FP8. Running the model needs at least that much memory across GPUs and system RAM, plus room for the context cache; quantized versions need less.
