316 The model's current lifecycle stage.
317
318 - `active`: The model is available for use, open to new adopters, and not scheduled for retirement.
319 - `deprecated`: The model remains callable for organizations with existing access, but is headed for retirement and closed to new adopters.
320 - `retired`: The model is no longer available for use; inference requests naming it fail. It remains in the catalogue as the historical record of its retirement.
