NVIDIA Releases AITune: An Open-Source Inference Toolkit That Automatically Finds the Fastest Inference Backend for Any PyTorch Model

NVIDIA open-sourced AITune, an Apache 2.0 Python toolkit for optimizing PyTorch inference on NVIDIA GPUs.

AITune benchmarks and tunes models across backends including TensorRT, Torch-TensorRT, TorchAO, and Torch Inductor.

It supports both ahead-of-time and just-in-time workflows, validates output correctness, and saves the best configuration as a reusable artifact.

The toolkit cuts manual deployment work by automating backend selection and performance testing, helping improve production inference efficiency.
