The PEtab extension for model selection, including the additional file formats and package.
The Python 3 library provides both the Python 3 and command-line (CLI)
interfaces, and can be installed from PyPI, with pip3 install petab-select.
Further documentation is available at http://petab-select.readthedocs.io/.
There are example Jupyter notebooks covering visualization, custom non-SBML
models, and the CLI and Python API, in the doc/examples directory.
The notebooks can be viewed at https://petab-select.readthedocs.io/en/stable/examples.html.
PEtab Select offers various methods and criteria for model selection, as well as a variety of visualization options.

Note that the directional methods (forward, backward) find models with the smallest step size (in terms of number of estimated parameters). For example, given the forward method and a predecessor model with 2 estimated parameters, if there are no models with 3 estimated parameters, but some models with 4 estimated parameters, then the search may return candidate models with 4 estimated parameters.
