Target Users

• AI engineers and researchers performing model architecture analysis
• Users who need to compare pre- and post-optimized models

Key Features

1. Diff Mode

Compare two models side-by-side to visually identify structural differences such as added, removed, or modified nodes.

• Topology Visualization: Verify optimization patterns by visualizing topology changes before and after graph optimization.
• Multiple View Layouts: Supports various comparison layouts including Basic, Parallel, Derived, and Aligned views to suit different analysis needs.
• Summary Indicators: Provides quick insights with indicators for similarity percentage, total node count, and added/deleted nodes.

2. Node Coloring

Assign custom colors to operators for faster structural understanding and analysis.

• Highlight Important Ops: Highlight operations that are important to your experiment by assigning custom colors or using predefined sets.
• Conditional Attribute Coloring: Apply custom colors by specifying conditions for desired attribute or metadata values, allowing for precise visual filtering.

3. Synced Control

Enabling Synced Control synchronizes the viewpoint between the source and target models, making the exploration of structural differences and localized topology changes significantly more efficient.

4. Fast Loading Performance for LLMs & Large Graphs

Netspresso Probe is engineered with an optimized parsing engine designed to handle massive computation graphs. While standard visualization tools often suffer from lagging or crashes when loading LLMs, Netspresso Probe ensures smooth and stable rendering.
