Build Local AI Apps with C++ and NVIDIA TensorRT RTX Samples

The Nvidia Deploy repository provides open‑source C++ samples that pair ONNX Runtime with the TensorRT RTX execution provider to accelerate local inference on Windows and Linux. It separates model export (via a Python exporter converting Hugging Face checkpoints to ONNX) from deployment, supporting tasks such as automatic speech recognition (Whisper, Parakeet, Nemotron), image segmentation (Meta SAM 2.1), and prompt‑driven generation (FLUX.2-klein-4B). Performance benchmarks on DGX Spark show GPU speedups up to ~200× over CPU, while post‑training quantization via NVIDIA Model Optimizer yields drop‑in ONNX replacements that require no code changes.
