PyTorch Mobile for iOS and Android devices launched last fall as part of the rollout of PyTorch 1.3, with speed gains coming from quantization, Google TPU support, and a JIT compiler upgrade.

The latest version of Facebook's open source deep learning library PyTorch comes with quantization, named tensors, and Google Cloud TPU support.

Facebook has already used a prototype of the Android Neural Network API that supports PyTorch to enable immersive 360-degree backgrounds on Messenger video calls.

Microsoft delivers another piece of its Copilot Runtime: an Arm version of the popular AI development framework.
