Human-in-the-Loop (HITL)

Definition

Human-in-the-Loop (HITL) is a system design approach where human input is incorporated into automated or AI-driven processes.

AI systems handle analysis and execution, while humans supervise, validate, or intervene in critical steps. This ensures that decisions are not fully automated but supported by human judgment, especially in complex or high-risk scenarios.
