Agent Autonomy Level
In one line
Agent autonomy level describes how far an agent acts on its own without human intervention — usually in stages, much like the autonomous driving levels people are already familiar with.
Going deeper
Agent autonomy level is a way to talk about how far an agent acts on its own — from 'recommends only' to 'decomposes and executes goals without humans'. The framing usually maps onto the autonomous-driving stages: Level 0 manual, Level 1 suggestion, Level 2 execute on approval, Level 3 autonomous within bounds, Level 4 broadly autonomous, Level 5 fully autonomous.
It is useful in practice because the risk and value scale differ by level. Higher-autonomy agents do more damage when they fail, so permissions, approvals, logging and rollback need to be designed to match. A common production pattern is to operate the same underlying agent at different levels for different task types.
The same thinking maps cleanly onto marketing and ecommerce. Deciding up front whether the AI 'suggests' a campaign, 'launches after human approval', or 'launches and is reviewed after the fact' makes the ROI of agent adoption far easier to measure.
