Android 8.1 Oreo goes final, rolling out now to Pixel and Nexus devices
After two developer previews, Android 8.1 Oreo is ready for the masses. Google announced that the new OS is rolling out now and is posting system images for the Pixel 2 and 2 XL, the Pixel 1 and 1 XL, the Pixel C tablet, and the Nexus 6P and 5X. The Android Open Source Project (AOSP) code drop should be happening now, too.
Android 8.1 Oreo is a minor maintenance release after the major update of Android 8.0. The biggest feature in 8.1 is a new "Neural Networks API" (NNAPI), which is designed for running machine learning operations on mobile devices. Phones with specialized machine learning hardware can hardware accelerate this API, while older devices can use a CPU fallback mode. The API provides a base layer higher-level machine learning framework to plug into, like Google's TensorFlow Lite.
