Licenses and commercial use Conditional
GLM-5.3 License
Close to MIT: commercial use, modification and redistribution are allowed. Keep the copyright notice and license text, and follow applicable laws. There is one condition aimed at very large operators: if you run a "Model as a Service" business (giving third parties inference or fine-tuning access) and you and your affiliates earn more than US$10 billion over any 12 months, you must pass Z.AI's security review before commercial use.

Models under GLM-5.3 License (1)
We use the license on the Hugging Face page of the original model (the model the quantization was made from), not the label on the GGUF repository, because the two often differ (for example, Gemma 4's original model is Apache 2.0, but many GGUF repositories label it gemma).
The summary states facts this site read from the original text and is not legal advice. Always check the original license and its latest terms before use. All licenses
