# Load Pre-Trained Model

> Learn how to load a pre-trained model in ReinforceUI Studio.

One of the key features of **ReinforceUI Studio** is the ability to load and analyze pre-trained models. If you have a log folder from a previous training session, you can load the model, visualize its policy performance, and observe the agent executing the task.

This feature is especially useful for:

* Reviewing a specific training session
* Comparing different models
* Refining and optimizing your models over time

## How to Load a Pre-Trained Model

<Tip>
  We recommend using log folders created by ReinforceUI Studio to ensure compatibility.
</Tip>

Follow these simple steps to load a pre-trained model in ReinforceUI Studio:

1. Click on the "Load Pre-Trained Model" button on the main screen.

2. Select the log folder containing the pre-trained model.

3. Automatic Setup:
   * The system will search for the required config file and model file.
   * It will automatically create the environment and load the model.
   * If successful, you will see the platform, environment, and algorithm names in green.
   * If there's an issue, an error message in red will indicate what went wrong.

4. Press "Test Policy" to observe the agent executing the task.

***

That's it! 🎉
You can now visualize the model's policy performance, compare it with other models, and refine your training process efficiently.
