Apple anticipates releasing system updates for iOS 26, iPadOS 26, and macOS Tahoe 26 next month. These updates will mark a significant advancement, upgrading the ChatGPT core model within Apple Intelligence from GPT-4 to the state-of-the-art GPT-5. Post-upgrade, users can expect enhanced accuracy, improved multimodal understanding, and faster response times in Siri, system-wide writing tools, and visual intelligence applications. GPT-5 will also introduce novel features, including real-time conversation translation and screen-level visual intelligence. Furthermore, Apple will make APIs for the on-device base model available to developers, empowering third-party applications to harness edge intelligence capabilities.
