Human-in-the-Loop (HITL)
What is Human-in-the-Loop (HITL)?
A design pattern in which humans are incorporated into the AI decision-making process — either to provide training labels, to review AI outputs before acting on them, or to handle cases the AI cannot resolve confidently. HITL is the recommended approach for high-stakes AI applications in legal, medical, financial, and HR contexts.
Example in practice
A bank's AI loan approval workflow that routes low-confidence predictions to a human underwriter for review is a well-designed HITL system — automating routine cases while keeping humans accountable for edge cases.
