+ ### Añadir Nuevos Modelos
785
+
786
+ Para añadir un nuevo modelo al sistema:
787
+
788
+ ```python
789
+ MODEL_CONFIGS.append({
790
+ 'name': 'Nombre del Modelo',
791
+ 'id': 'huggingface/model-id',
792
+ 'type': 'vit', # o 'swin', 'efficientnet'
793
+ 'description': 'Descripción del modelo',
794
+ 'emoji': '🤖'
795
+ })
796
+ ```
797
+
798
+ ### Tipos de Modelos Soportados
799
+
800
+ - **vit**: Vision Transformer
801
+ - **swin**: Swin Transformer
802
+ - **efficientnet**: EfficientNet
803
+ - **foundation**: Modelos foundation (como Google Derm)
804
+
805
+ ### Pesos del Ensemble
806
+
807
+ Los pesos se asignan automáticamente según:
808
+ - Tipo de modelo (foundation > swin > efficientnet > vit)
809
+ - Confianza de la predicción
810
+ - Histórico de rendimiento
