## AI overview

Human-in-the-loop workflows add human judgment to AI and machine learning decisions to improve reliability, quality, and trust. The article describes the trade-off: automation can increase speed and scalability but may raise error risk, while human oversight can improve accuracy and safety at the cost of latency and expense. It proposes tiering human review toward decisions where it is most useful.
