Note

Sentis is now called Inference Engine. The documentation has moved to https://docs.unity3d.com/Packages/com.unity.ai.inference@latest. Refer to the new location for the latest updates and guidance. Make sure to update your bookmarks and references accordingly.

Import a model file

To import an ONNX model file, drag the file from your computer into the Assets folder of the Project window.

If your model has external weights files, put them in the same directory as the model file so that Sentis imports them automatically.

To learn about the models Sentis supports, refer to Supported models.

Create a runtime model

To use an imported model, you must use ModelLoader.Load to create a runtime Model object.

using UnityEngine;
using Unity.Sentis;

public class CreateRuntimeModel : MonoBehaviour
{
    public ModelAsset modelAsset;
    Model runtimeModel;

    void Start()
    {
        runtimeModel = ModelLoader.Load(modelAsset);
    }
}

You can then create an engine to run a model.
