Autonomy Level
A classification of how independently an AI agent operates, typically on a scale from fully human-controlled to fully autonomous. Level 1: human does the task, agent assists. Level 2: agent drafts, human approves (Human-in-the-Loop (HITL)). Level 3: agent executes, human reviews after. Level 4: agent executes autonomously, human handles exceptions (Human-on-the-Loop (HOTL)). Most production agents operate at Level 2–3, with Level 4 reserved for low-risk, high-volume tasks. Autonomy is best assigned per action, not per agent — the same agent can run at Level 4 for reversible actions and Level 2 for irreversible ones.

Example
A support agent starts at Level 2 (drafts responses, human sends). After three months of consistent quality, it's promoted to Level 3 (sends automatically, human reviews a sample). Low-risk password resets run at Level 4 (fully autonomous).
Frequently asked questions
- How do you decide what autonomy level to give an agent?
- Consider three factors: risk (what's the worst outcome of a mistake?), reversibility (can you undo a bad action?), and confidence (how reliably does the agent handle this task?). High risk + low reversibility = low autonomy. Low risk + high reversibility + proven accuracy = high autonomy.
