CheckpointVariant

class openstef_foundation_models.models.catalog.CheckpointVariant(*values)

Bases: StrEnum

A published ONNX variant of a model’s weights.

DYNAMIC = 'dynamic'

STATIC = 'static'

property filename_suffix: str

The suffix this variant adds to the model slug in the weights filename.

Returns:

'_static' for the static-shape variant, '' for the dynamic one.

classmethod recommended() → CheckpointVariant

The variant to prefer on the host running this code.

Returns STATIC on macOS, where frozen shapes let the CoreML provider engage in the default fallback chain, and DYNAMIC everywhere else. The choice is by platform only — it never imports the inference runtime — so static is recommended on macOS even when CoreML is absent, where it simply runs on CPU like the dynamic build.

Return type:

CheckpointVariant

Returns:

The recommended variant for this host.
