Apple plans to upgrade the core ChatGPT model in Apple Intelligence from GPT-4o to the latest GPT-5 in the upcoming iOS 26, iPadOS 26, and macOS Tahoe 26 system updates next month. This upgrade will significantly enhance the accuracy, multi-modal understanding capabilities, and response speed of Siri, system-level writing tools, and visual intelligence.
The addition of GPT-5 not only brings performance improvements but also unlocks several new features, including real-time multilingual conversation translation and visual intelligence capabilities that can understand and analyze the current screen content. These upgrades will further enhance the practicality of devices in cross-language communication and complex information processing.
Additionally, Apple will open the API for on-device base models to developers for the first time, allowing third-party applications to directly call edge-side intelligent capabilities, thereby bringing low-latency, high-privacy AI experiences to more scenarios. This move is expected to continuously expand the application scope of Apple Intelligence within the ecosystem.
