 * EP context [unit tests](https://github.com/microsoft/onnxruntime/blob/main/onnxruntime/test/providers/nv_tensorrt_rtx/nv_ep_context_test.cc)
 
 
+There are two other ways to quick generate an EP context model
+
+1. **ONNX Runtime Perf Test**
+
+```sh
+onnxruntime_perf_test.exe -e nvtensorrtrtx -I -r 1 "/path/to/model.onnx" --compile_ep_context --compile_model_path "/path/to/model_ctx.onnx"
+```
+
+2. **Python Script**
+
+```sh
+python tools/python/compile_ep_context_model.py -i "path/to/model.onnx" -o "/path/to/model_ctx.onnx"
+```
