+        Enables accessing model attributes directly through the Model class.
+
+        This method provides a way to access attributes of the underlying model directly through the Model class
+        instance. It first checks if the requested attribute is 'model', in which case it returns the model from
+        the module dictionary. Otherwise, it delegates the attribute lookup to the underlying model.
+
+        Args:
+            name (str): The name of the attribute to retrieve.
+
+        Returns:
+            (Any): The requested attribute value.
+
+        Raises:
+            AttributeError: If the requested attribute does not exist in the model.
+
+        Examples:
+            >>> model = YOLO("yolo11n.pt")
+            >>> print(model.stride)
+            >>> print(model.task)
