302 - `deprecated_at: string or null`
303
304 RFC 3339 datetime string representing the time of the model's most recent deprecation. Populated for `deprecated` and `retired` models; `null` while the model is `active`.

312 - `lifecycle: "active" or "deprecated" or "retired"`
313
314 The model's current lifecycle stage.
315
316 - `active`: The model is available for use, open to new adopters, and not scheduled for retirement.
317 - `deprecated`: The model remains callable for organizations with existing access, but is headed for retirement and closed to new adopters.
318 - `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.

296330 The model line this model belongs to, such as `opus` for both Claude Opus 4.5 and Claude Opus 4.6. More lines may be added. `null` when the model belongs to no line; do not infer a line from the `id`.

350 - `retires_at: string or null`
351
352 RFC 3339 datetime string representing the model's currently scheduled retirement date. The schedule can be revised until retirement occurs; `null` while the model is `active` or while no retirement is scheduled. A past date on a `deprecated` model means retirement is overdue, not that it has occurred: `lifecycle` is the retirement signal.
