ExecuTorch

PyTorch's toolkit for running AI models directly on phones, laptops, headsets and tiny chips.

New this week

What it does

ExecuTorch is software from the PyTorch project for running AI models on devices themselves, such as phones, wearables, laptops, browsers and microcontrollers, rather than on remote servers.

Developers take a PyTorch model, prepare it for a particular device, and run it from many programming languages. It covers chat models, speech recognition and synthesis, image understanding and more. Its makers say it powers on-device features in Instagram, WhatsApp and Meta's headsets and glasses.

Who it's for

App and hardware developers who want AI to run privately and offline on devices.
