What can an AI agent do?
The VOCE A0–A4 reference distinguishes the scope of action and the controls to examine. These are operational categories, not a numerical performance scale.

A0 · Assistant
Generates or retrieves information without external action.
Human responsibility: Review the answers and their sources.
A1 · Connected tools
Uses approved tools for reading or low-impact tasks.
Human responsibility: Limit access and ensure it can be revoked.
A2 · Delegated action
Performs business actions within a defined mandate.
Human responsibility: Set transaction limits, approvals and recovery procedures.
A3 · Multi-agent system
Coordinates agents, models and tools across systems.
Human responsibility: Trace the delegation chain and evaluate shared outcomes.
A4 · Critical network
Operates in contexts with potentially critical consequences.
Human responsibility: Assign an accountable owner and test emergency intervention.
A4 describes criticality; it does not mean self-improvement. The appropriate category depends on the use case. These levels belong to the VOCE reference and are not an EU certification.
