 ## What is ExecuTorch?
 
-ExecuTorch is a novel AI framework developed by Meta, designed to streamline deploying PyTorch models on a variety of devices, including mobile phones and microcontrollers. This framework enables exporting models into standalone binaries, allowing them to run locally without requiring API calls. ExecuTorch achieves state-of-the-art performance through optimizations and delegates such as Core ML and XNNPACK. It provides a seamless export process with robust debugging options, making it easier to resolve issues if they arise.
