The on-device language models provided by Apple are designed to be consistent across different devices, including Mac and iPhone. The Foundation Models Framework gives access to the same on-device large language model across macOS, iOS, iPadOS, and VisionOS. This model is built into the operating systems and is optimized for various tasks such as content generation, text summarization, and user input analysis, all while maintaining privacy by running entirely on the device. Therefore, the language models are the same for both Mac and iPhone, ensuring a consistent experience across Apple's ecosystem.
