# Agents and Agent Versions

> Understand how Voker separates an agent's logical identity from its versioned configurations, so you can iterate safely and compare behavior over time.

## Agents

An agent represents a logical assistant or capability, identified by its purpose, such as "Support Bot" or "Document Analyzer." It remains stable while its versions evolve.

## Agent Versions

An agent version represents a specific configuration of an agent at a point in time. This includes the model, system prompt, tool configuration, and any other behavioral settings. Every agent execution is tied to a single Version. Instead of editing Versions in place, you create new ones, giving you a clear history of changes, side-by-side comparisons, and the ability to revert safely.
