Scenario

This section describes the typical service scenarios of graph build and run. You can perform services as required.

**Table 1** Graph build and run
Scenario	Function Usage	Applicable Products
Building a Graph into an Offline Model	Build a graph and save it as an offline .om model. Load the model through the model loading API, and call the model run API for inference. For details, see section "Model Management" in Application Development (C & C++).	All
Building and Running a Graph	After a graph is constructed, build and run the graph directly. Use AddGraph to load the graph object. When the graph is running, the following two scenarios are involved based on the called API: Synchronous mode: After the graph is loaded, use RunGraph to run the graph synchronously to obtain the result. Asynchronous mode: After the graph is loaded, use RunGraphWithStreamAsync to run the graph asynchronously to obtain the result.

Building a Graph into an Offline Model

In this scenario, a graph is compiled and saved as an OM offline model. Figure 1 shows the process. For details about services, see Graph Build to an Offline Model.

Building and Running a Graph

Figure 2 shows the workflow of constructing, building, and running a graph. For details about services, see Graph Build and Run.
