# Simulation

<a href="/release-notes/2026.3"><Badge className="version-badge" color="blue">Added in 2026.3</Badge></a>

With *Simulation* mode, you can simulate conversations for your LLM-based AI Agents using [predefined scenarios](/ai/agents/test/simulator/overview). This mode allows you to test and debug your AI Agent's behavior in various situations without needing real user input.

## Restrictions

* Simulations don't work with Snapshots in the Interaction Panel.
* AWS Bedrock's `amazon.nova-premier-v1:0` and `amazon.nova-2-lite-v1:0` models aren't supported to run simulations.

## How to Use Simulation Mode

To open simulation mode, click the <img src="https://mintcdn.com/cognigy-15abf2ba/WLWtdAYHA6nv5QU9/_assets/icons/black-and-white/simulation.svg?fit=max&auto=format&n=WLWtdAYHA6nv5QU9&q=85&s=e4b6c8d539ec8e78b318563e243c1193" alt="simulation" width="22" height="22" data-path="_assets/icons/black-and-white/simulation.svg" /> tab in the [Interaction Panel](/ai/agents/test/interaction-panel/overview), then select the scenario to run the simulation on.

The simulation of the selected scenario starts with the following predefined settings:

* The number of simulation runs is 1 and can't be changed.
* The simulation uses the [default LLM](/ai/agents/develop/gen-ai-and-llms/other-operations#set-a-model-as-default) selected on the **Large Language Models** page.
