You work for a toy manufacturer that has been experiencing a large increase in demand.

AutoML Vision Edge is a service that allows you to create custom image classification and object detection models that can run on edge devices, such as mobile phones, tablets, or IoT devices 1 .  AutoML Vision Edge offers four types of models that vary in size, accuracy, and latency: mobile-versatile-1, mobile-low-latency-1, mobile-hig h-accuracy-1, and mobile-core-ml-low-latency-1 2 . Each model has its own trade-offs and use cases, depending on the device specifications and the application requirements.

For the use case of building an ML model to reduce the amount of time spent by quality control inspectors checking for product defects, the best model to use is the AutoML Vision Edge mobile-low-latency-1 model.  This model is optimized for fast inference on mobile devices, with a latency of less than 50 milliseconds on a Pixel 1 phone 2 . Faster defect detection is a priority for the toy manufacturer, and the factory does not have reliable Wi-Fi, so a low-latency model that can run on the device without internet connection is ideal.  The mobile-low-latency-1 model also has a small size of less than 4 MB, which makes it easy to deploy and update 2 .  The mobile-low-latency-1 model has a slightly lower accuracy than the mobile-high-acc uracy-1 model, but it is still suitable for most image classification tasks 2 . Therefore, the AutoML Vision Edge mobile-low-latency-1 model is the best option for this use case.
