A model and the product around it are different things: a result for one does not carry over to the other.
Lifecycle ≠ availabilityThe provider retired this model on 15 Jun 2026. According to an older statement, Claude Enterprise, Claude Team still list it; a retired model is not counted as usable anywhere.
Where can it be used?
Only recorded availability statements are shown. A missing plan or surface means unknown, not unavailable. Where it applies only to a plan or a region, the row says so. “Rolling out” is not “available”. “Rollout reported” means a rollout was reported, but nothing has supported it for more than 90 days.
