Human-in-the-Loop
Keeping a human approval step in an AI workflow for oversight and safety.
Definition
Human-in-the-loop (HITL) is a design principle where AI systems are required to pause and obtain human approval before taking consequential actions. Rather than fully autonomous operation, the AI handles the information gathering and drafting while humans review, approve, or override before the action executes. HITL is the responsible deployment pattern for AI in any process where errors have material consequences — financial transactions, customer communications, regulatory filings.
