·2026.08.22 08:02

Run models from various frameworks such as PyTorch, TensorFlow/Keras, scikit-learn, LightGBM, and XGBoost within a single runtime. The core objective is to increase inference speed and reduce costs through hardware accelerator utilization and graph optimization.

By adding just one line to existing PyTorch training scripts, you can reduce training time for Transformer models in multi-node NVIDIA GPU environments. This approach integrates directly into existing workflows without requiring framework changes.

It provides language bindings for multiple languages including C++, C#, Go, Java, JavaScript, Rust, and Objective-C. Released under the MIT license, it can be freely used in commercial projects.

It is suitable for environments that require consistent performance across diverse hardware and operating systems. It is particularly useful for developers planning large-scale model inference or distributed training that requires GPU acceleration.
