Five Levels of AI Autonomy

Adapted from the SAE J3016 standard for vehicle automation, AI autonomy can be categorized into five levels:

LevelNameDescription
0ManualNo automation; humans do everything
1AI-AssistedAI provides decision support; humans decide and act
2Semi-AutonomousAI acts with human approval for significant actions
3Conditionally AutonomousAI executes defined tasks; humans intervene for exceptions
4Fully AutonomousAI manages end-to-end; humans govern and audit

The progression is not merely technical, it’s about trust transfer. Each level represents a different allocation of cognitive load and accountability between human and machine.

Most effective deployments don’t pick a single level. They assign different levels to different tasks based on risk, complexity, and the AI system’s demonstrated reliability.
