# Features

## Model Visualization

Ability to graphically view model architecture, including connectivity, node, and tensor parameters.

Includes:

> 
> 
> - Network search for nodes and tensors
> - Ability to overlay accuracy and performance results
> - Visualize ops and tensors mapped between two models with [op source mapping](https://docs.qualcomm.com/doc/80-87189-1/topic/visualization.html#op-mapping-ui)
> - Compare models side-by-side with [model diff](https://docs.qualcomm.com/doc/80-87189-1/topic/visualization.html#model-diff)

## Analytics

QAIRT Visualizer provides different model analytics visualization for debugging models.

### Performance metrics

Shows profiling details for a model run on a given Qualcomm AI Stack runtime. QAIRT Visualizer shows these metrics in chart form with the ability to locate profiling details at an operation level. The performance metric for an operation is also mapped in the model visualization view to help locate the operation within the model. Additionally, a summary of performance details is provided for metrics such as execution and init times.

Note

Support for JSON output with schema version greater than or equal to 2.0.0, but less than 3.0.0.

### Accuracy metrics

Shows accuracy outputs for a model based on reports generated by the QNN Accuracy Debugger tool. QAIRT Visualizer shows these output metrics in chart form with the ability to locate accuracy details at an operation level. The accuracy output for an operation is also mapped in the model visualization view to help locate the operation within the model.

Note

Support for JSON output schema version 0.1.0. Compatibility with future versions is not assured.

### Optrace

Provides the ability to visualize the opstats data for a model, which helps users get insight on the performance bottlenecks in the AI model execution. Model op traces provide internal graph execution details in the form of per-operation cycle counts across each hardware thread. QAIRT Visualizer shows this data mapped back to the Qualcomm AI Stack nodes as a trace graph view.

Note

Support for JSON output with schema version greater than or equal to 1.0.0, but less than 2.0.0, as well as plain chrometrace schema formats.

### Genie Trace

Visualizes Genie Trace JSON reports, which display detailed runtime execution traces for GenAI models.

Note

Support for JSON output with schema version greater than or equal to 1.0.0, but less than 2.0.0, as well as plain chrometrace schema formats.

### Runtrace

Visualizes Runtrace JSON reports, which display high-level profiling events. This is especially useful for understanding preemption and concurrency in multi-graph scenarios.

Note

Support for JSON output with schema version greater than or equal to 1.0.0, but less than 2.0.0, as well as plain chrometrace schema formats.

### QNN HTP Analysis Summary

Visualizes QNN HTP Analysis Summary (QHAS) JSON reports, which provide user-friendly, summarized data and charts from running models with HTP runtime. Details include overall HTP resource utilization, active cycles, dominant cycle path, and tracing back to the original QNN graph.

Note

Support for JSON output with schema version greater than or equal to 1.0.0, and less than 2.0.0.
