We Pinned Our Model Version to Stay Safe. The Provider Deprecated It Anyway.

A production AI model pinned to a specific version was deprecated by its provider despite efforts to avoid change, highlighting that pinning delays but does not prevent model updates. This reveals an often overlooked cost in AI deployment: the re-qualification tax, or the effort to revalidate systems after model changes. Teams must plan for scheduled model deprecations as providers accelerate model updates and retirements.
