Models under S1-mini License (Apache 2.0 + an additional clause) (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).
