Why AI output needs its own QA
Generated work fails differently from human work. It is fluent, well formatted and confident, which is exactly why it passes the glance test that most review processes rely on. The defects sit in assumptions rather than syntax: a function that handles the happy path and silently returns nothing for the rest, a statistic with an invisible source, a screenshot that lost the metadata proving where it came from.
Traditional QA assumes a fixed requirement and a deterministic intent. Generative pipelines have neither. What they do have is repeatable failure modes, and those can be tested.
