- CreateModel — Model for creating a new model.
  - `name` string, required — The name of the model.
  - `description` string, nullable — An optional description for the model.
  - `pybamm_version` string, nullable — PyBaMM version used for this model. If not provided, will be read from pybamm.__version__.
  - `chemistry` 'lithium_ion' | 'lithium_sulfur' | 'ecm' | 'generic' — Model chemistry kind: 'lithium_ion' (default — assumes pybamm lithium-ion conventions), 'lithium_sulfur', 'ecm', or 'generic' (no chemistry-specific enrichment).
  - `simulation_settings` object, nullable — Optional persistent simulation kwargs (var_pts / submesh_types / spatial_methods / geometry / solver) in the flat canonical form, re-applied at simulation time. None uses the model defaults.
  - `config` object, required — Model configuration stored as JSON.
