Agent Autonomy Levels
Autonomy is a spectrum — from a chatbot with tools to a long-horizon agent running unattended. Spend risk scales with autonomy.
The spectrum
Level 1 — Tool-assisted assistant: human in the loop for every action.
Level 2 — Routed workflow: agent acts within a fixed process.
Level 3 — Autonomous task: agent runs a task end-to-end.
Level 4 — Long-horizon autopilot: agent works for hours or days unattended.
The spend implication
Each level up multiplies tool calls and removes human review.
Level 3–4 agents need deterministic gates — there's no human in the loop.
FAQ
What autonomy level needs a firewall?
Any agent that can spend — but gates matter most at levels 3–4.
Is autonomy the goal?
It's a trade: more autonomy, more control required.
