Human-in-the-Loop (HITL)
Human-in-the-loop is a design pattern where a human reviews, edits, or approves AI output before it takes effect — combining AI scale with human judgment at decision points.
HITL is the responsible default for AI workforce. Where pure automation gets you speed, HITL gets you speed + a brain on the irreversible moves. The interesting design question is which loops keep a human and which graduate to autonomous; the answer is usually 'gate the irreversible, autonomate the rest'.
Example
AI Recruiter screens 200 applications, ranks them, and presents the top 12 with notes. The human hiring manager picks 6 to interview — humans-in-loop on the decision, AI-out-of-loop on the volume.
How OpenLabor uses it
OpenLabor's approval gates make HITL the default for sensitive actions and let you turn it off as confidence grows.
Doesn't HITL slow everything down?
Only on the steps that have a human. The volume below the human's attention runs full speed.
