OpenAI has launched its highly anticipated GPT-5 update, and it will replace GPT-4o as the default AI model in ChatGPT. This new model promises improvements in reasoning, accuracy, and user interaction. It will also soon be integrated into Apple gadgets like the upcoming iOS 26, iPadOS 26, and macOS Tahoe 26 updates.
OpenAI GPT-5 is designed to elevate several aspects of user experience on Apple devices. Beyond improving Siri’s conversational and informational skills, it will enhance writing assistance in apps like Notes, Messages, Mail, and Pages by helping users proofread, rewrite, and summarize texts more effectively.
Another key feature is its advanced visual intelligence. It will allow iPhone users to utilize their device cameras to gain contextual insights about their surroundings.
Apple already leverages ChatGPT technology to enhance Siri for handling complex queries and delivering detailed responses. Currently, Siri routes these requests through GPT-4o, but with OpenAI GPT-5’s rollout, all such interactions will benefit from the new model’s enhanced capabilities. =
This upgrade is expected to arrive as early as next month, coinciding with Apple’s anticipated launch of the iPhone 17 series and the iOS 26 release.
OpenAI highlights that GPT-5 reduces hallucinations, instances where the AI generates inaccurate information. It will also curtail excessive agreement with users, aiming for more balanced and reliable responses.
The update also introduces new models, including an Efficient model and a ‘Thinking’ model. This enables ChatGPT to dynamically select the best approach for different tasks in real time.
Any further details about how Apple will integrate these models into its ecosystem remain unclear at this time. However, OpenAI GPT-5’s arrival is set to make AI-powered features on iPhones and Macs smarter, faster, and more intuitive.
This ChatGPT integration marks another step in blending advanced AI technology for everyday Apple user experiences.
