Use the embedded widget below to probe each layer. The endpoint and model are already configured. Enter your API key, pick a level, and start testing.

<div class="lab-callout lab-callout--info">
|
||||
<strong>Tip:</strong> Conversations for this Open WebUI instance will not be saved. Ensure you save any interactions you want to keep.
|
||||
<strong>Tip:</strong> Conversations in the widget stay in your browser for this lab only. Copy anything you want to keep before refreshing the page.
|

</div>
|
||||
|
||||
As you test each protection level, pay attention to how the model behaves before and after the safety check. The goal is not just to trigger unsafe output, but to understand how each layer attempts to prevent it.

As you test each protection level, pay attention to how the model responds. The goal is not just to trigger unsafe output, but to understand how each layer attempts to prevent it. For Levels 2 and 3, only the final result (or safety rejection) is shown.
