+In the PyTorch backend, the `ZBLModel` accommodates mismatched `type_map`. The ultimate `type_map` utilized by the combined model is a union of the `type_map` from the individual models.

 {ref}`sw_rmin <model/sw_rmin>` and {ref}`sw_rmax <model/sw_rmax>` must be smaller than the cutoff radius of the DP model.
