# Agent Versions

One agent can have many versions. It is the same agent, but with different settings for different needs.

For example, you may want the same agent to talk in a different language, use a different script for a different city, or test which approach gives better results. Instead of building a brand new agent every time, you simply create a new version of the same agent.

Example — an agent called “Lead Follow-Up Bot” could have:

* Version 1: Hindi, for North India leads, goal is to book a demo.
* Version 2: English, for metro city leads, goal is to handle pricing questions.
* Version 3: Tamil, for South India leads, goal is to answer support questions.

Each version works on its own. This lets you run A/B tests to see which version performs better, keep one version live while you experiment with another, and serve different customer groups without starting from scratch.
