Samples

The package ships importable samples. In the Unity Package Manager, select this package, open the Samples tab, and click Import next to any of:

• Basic Inference — runs a tiny embedded ONNX model end-to-end to confirm the runtime works. No external assets required.
• GenAI Text Generation — text generation with ONNX Runtime GenAI. Requires a local GenAI model folder (set its path in the Inspector).
• Extensions (Preprocessing) — runs an ONNX Runtime Extensions custom op via SessionOptions.RegisterOrtExtensions(). No external assets required.

Each imported sample includes a README.md with step-by-step instructions.
