Google has been shipping custom NPUs since the Pixel 4 in 2019. Prior to that, Google phones just used off the shelf SOCs from Qualcomm, with 2018's Pixel 3 using the NPU in the Snapdragon 845. Android first shipped NNAPI in Android 8.1 in 2017, with acceleration on various mobile GPUs and DSPs, including the Pixel Visual Core on the Pixel 2. Google has shipped more on-device models so far, but neither company has a moat for on-device inference.
