The **Tune your model** phase on your model's overview takes you to the NLU Expert Feedback Loop feature, which collects data from Virtual Agent chat logs and provides it to you for feedback.

**Note:** The ServiceNow® Store application NLU Workbench - Advanced Features must be installed to view **Tune your model**. The Virtual Agent plugin is also required.

When the Expert Feedback Loop has feedback waiting for your review, **You have utterances that need feedback** is highlighted on the card.
