This article discusses how Apple Inc. has leveraged artificial intelligence to enhance fundamental features in its new iPhone 15 series and smartwatches. Apple has developed a new chip for the Series 9 watch, which includes enhanced data processing capabilities, particularly with the addition of a quad-core "neural engine" that doubles the speed of machine learning tasks. The AI components of Apple's new watch chip have improved Siri's accuracy by 25%. Additionally, the image capture of the iPhone series has been enhanced, with the camera automatically recognizing people in the frame and collecting data needed for blurring the background. Although Apple has not attempted a major transformation using artificial intelligence like some other companies, AI has been quietly revolutionizing Apple's core software products behind the scenes.
