Human in the loop
Also known as: HITL, human oversight
What is human in the loop?
Human in the loop means a person reviews or approves AI output before it takes effect. It is the standard control for automated decisions with financial, legal, safety or reputational consequences.
The design question is not whether to have humans, but where the approval boundary sits and how much volume a reviewer can realistically handle. Approval steps that no one has time to perform become rubber stamps.
