Step 2: Upload a Second Model to Use Diff Mode

Diff Mode allows you to compare two model graphs and visually identify structural differences such as added, removed, or modified nodes.

By visualizing topology changes before and after graph optimization, you can easily verify which optimization patterns were applied and plan subsequent experiments more efficiently.

Quick Start: Experience with Sample

If you want to explore Diff Mode capabilities without uploading your own models, you can try the interactive sample page.

Click the "Go to Sample Page" button located at the bottom-right corner of the main landing screen.

This launches a pre-configured session with demo models, allowing you to instantly experience the Diff Mode features and view types.

How to Activate

Toggle Diff On (top navigation)
Upload a second model
Choose Diff view type via Graph → Select Diff View Type

Diff View Types (4 Options)

NP Probe provides multiple visualization layouts for structural comparison:

Mode	Description
Basic View	Displays both graphs as they are, without highlighting any changes. Use this view when you want a clean side-by-side comparison without visual markers.
Parallel View	Highlights nodes missing from the left graph and nodes added in the right graph.Ideal for significant topology changes, where large portions of the model differ. After turning on the Diff toggle and uploading a second model, Parallel View is selected as the default option.
Derived View	Highlights node differences (added or missing) on the right graph only.Best suited for minor or localized topology changes.
Aligned View	Displays both graphs using a synchronized layout and highlights differences (added/missing) on the right graph.Most effective when the two models have minimal topology differences, allowing precise alignment-based comparison.

Summary Indicators

Displayed above the Diff view:

Similarity (%)
Total Nodes
Added Nodes
Deleted Nodes

These indicators provide a quick understanding of the model-to-model delta.
