What autonomy level should I buy?

Match the level to the job, both directions. Deterministic, stable-rules work → L0 workflow (don't overpay for autonomy you won't use). A human should keep final judgment → L1 copilot. Multi-step, ambiguous work needing runtime decisions and recovery → a real L2–L3 agent. Overpaying for an unusable L4 and buying L0 for an L3 problem both waste money.

Is fully autonomous (L4) better?

Not for most business tasks. Full autonomy fits low-stakes, reversible work. For high-stakes or irreversible actions, Human-in-the-Loop (HITL) supervision at L2–L3 is the standard—a vendor promising unsupervised L4 for your accounts-payable run is either agent washing or being reckless.

Levels of Autonomy (AI Agents)

Written by Max Zeshut

A five-level scale for classifying how much of a task an AI agent runs without human intervention—the agent analog of SAE's self-driving levels, and the antidote to Agent Washing. **L0 Scripted:** fixed rules / conversation trees (a chatbot or RPA flow). **L1 Assisted:** suggests and drafts, human executes every action (a copilot). **L2 Supervised:** plans and acts on routine steps, human approves high-stakes ones via an Approval Gate. **L3 Conditional:** runs end-to-end in a bounded domain with a Human-on-the-Loop (HOTL) monitoring. **L4 High:** runs open-ended tasks and self-corrects, human sets goals and guardrails. The honest floor for calling a product an 'agent' is L2; most real production agents live at L2–L3, and for anything touching money, contracts, or customers that supervised range is the responsible design, not a limitation.

Пример

In a support deployment: an L1 copilot drafts replies for an agent to send; an L2 agent resolves password resets autonomously but routes refund requests to an Approval Gate; an L3 agent handles all tier-1 tickets end-to-end while a supervisor watches the queue for exceptions. Writing the target level into the contract ('operates at L3 for tier-1 tickets, measured over a 30-day pilot') makes the claim testable in a way 'agentic' never is.
