The headline feature of the OS update seems to be a "Neural Networks API" (NNAPI), which Google says "provides apps with hardware acceleration for on-device machine learning operations." This sounds a lot like it will use the "Pixel Visual Core," the extra Google-designed SoC present in the Pixel 2—which we were told would be enabled with Android 8.1—but it's odd that Google doesn't mention it by name.
