After ChatGPT, GPT-5 is coming to your iPhones next: What to expect

OpenAI has officially unveiled its latest advancement, GPT-5, promising significant enhancements over its predecessor models in reasoning and performance. This cutting-edge model has already taken the reins as the default in ChatGPT and is gearing up for integration into iPhones, iPads, and other Apple devices with the anticipated release of iOS 26, iPadOS 26, and macOS Tahoe 26, according to a report by 9to5Mac. Apple has previously incorporated ChatGPT into its Siri voice assistant, enabling it to manage more complex inquiries and deliver detailed responses. While GPT-4o was the standard for handling user requests, the transition to GPT-5 will elevate this functionality even further. Reports suggest that GPT-5 may begin rolling out to Apple devices as soon as next month, coinciding with the launch of the iPhone 17 series set for early September, which typically precedes new iOS updates. With GPT-5, iPhone users can expect a multitude of enhancements across various applications. Siri will utilize the new model to tackle complex queries, including those related to photos and documents. Furthermore, users will have the capability to employ GPT-5 within numerous Apple and third-party applications, such as Notes, Messages, Mail, and Pages, for tasks like proofreading, rewriting, and summarizing text. In addition, GPT-5 will enhance Visual Intelligence, allowing users to leverage their phone's camera for gathering information about their environment. OpenAI asserts that this new model shows marked improvements in coding, writing, reasoning, and accuracy, particularly in health-related inquiries. Notably, GPT-5 is designed to minimize 'hallucinations,' or inaccuracies, and reduce overly agreeable responses. With features including an Efficient model and a GPT-5 Thinking model, the new system will streamline the user experience. Unlike previous versions where users had to select a model based on their specific needs, ChatGPT will now automatically connect to the most suitable model in real-time. While the exact implementation of this mechanism on Apple devices remains to be seen, the reasoning capabilities of GPT-5 are expected to significantly enhance Apple Intelligence. Stay tuned for more updates as this technology revolutionizes user interaction on Apple devices.
