The Roboflow [Model Evaluation](https://docs.roboflow.com/train/evaluate-trained-models) tool now supports instance segmentation projects. You can now use this tool to explore mAP by object size, identify the ideal confidence threshold based on precision/recall trade-off, view model accuracy by class, and more.

To use this feature, open a model in Roboflow and click on the "View Full Model Evaluation" button to view your model evaluation.

*Note: If your model was trained before the end of October 2025, a button may appear asking you to recompute your model evaluation. This will ensure our dashboard has all of the metrics now supported in our instance segmentation model evaluation suite.*
