 If base model is `sdxl`, the `type` attribute is set with possible values: `eps, edm, v-prediction, v-prediction-edm`
 
-The entry is `{"base_model": "unknown"}` for models which are not in safetensors format or do not match any of the known base models.
+Detection supports quantized models:
+* GGUF: if the `gguf` module is installed, .gguf files are detected and will set the `quant` field
+* Nunchaku: SVDQuant models are detected and will set the `quant` field to `svdq`
+
+Returns an entry `{"base_model": "unknown"}` for models with unknown format or which do not match any of the known base models.
