# Mosaic Augmentation

{% hint style="info" %}
Mosaic Augmentation is an Enhanced Augmentation, a **premium** feature.

For up-to-date information on our plans and their associated features, see our [pricing page](https://roboflow.com/pricing).
{% endhint %}

Mosaic combines several images (typically three to nine) into a single composite tile, shrinking and packing the originals together. This increases the number of objects per image and their scale variety, helping your model perform better on small objects.

{% hint style="danger" %}
Warning: Many modern models apply Mosaic as an online augmentation during training; applying it twice can cause undesirable results. We do not recommend using this with Roboflow 3.0 or YOLOv8.
