About

What is executorch?

ExecuTorch is PyTorch's unified solution for deploying AI models directly on-device, spanning from smartphones to microcontrollers. It's engineered for privacy, performance, and portability, powering Meta's on-device AI across various products. The tool allows developers to deploy LLMs, vision, speech, and multimodal models using familiar PyTorch APIs, accelerating research to production without manual C++ rewrites, format conversions, or vendor lock-in. Key features include native PyTorch export, a production-proven architecture, a minimal 50KB base runtime footprint, and support for over 12 hardware backends like Apple, Qualcomm, and ARM. It uses ahead-of-time (AOT) compilation to optimize models for edge deployment, offering a seamless workflow from export to execution.
