What it does
TensorRT is a software kit from NVIDIA for inference, which means running an AI model after it has been trained. It is designed to make models run quickly on NVIDIA graphics cards (GPUs).
This repository holds the open-source parts of TensorRT: add-ons called plugins, a tool that reads models saved in the common ONNX format, and sample apps. The main TensorRT release is downloaded separately from NVIDIA.
It is aimed at engineers who put AI models into products and need them to respond fast.
Who it's for
Software engineers and AI teams who deploy models on NVIDIA hardware.
