OpenAI’s GPT‑5 to Power Apple Intelligence in iOS 26

Apple has confirmed that its AI assistant platform Apple Intelligence will adopt OpenAI’s GPT‑5 in iOS 26, iPadOS 26, and macOS Tahoe next month, with upgraded Siri, writing, and visual AI tools (via 9to5Mac).

Currently, Apple Intelligence’s ChatGPT integration relies on the GPT‑4o model, delivering features such as Siri responses, creative writing assistance, and visual intelligence driven by your camera.

With the upgrade to GPT‑5, users can expect a substantial boost in reasoning, response quality, and speed. OpenAI describes GPT‑5 as its smartest, most capable model yet, now widely available to all ChatGPT users across free and paid tiers.

Reports confirm that Apple’s enhanced AI features will roll out with the next major software updates in the fall, likely arriving next month alongside Apple’s iPhone 17 event. These updates promise deeper ChatGPT integration across Siri, Writing Tools, and Visual Intelligence in Apple products.

GPT‑5 isn’t just smarter; it’s more efficient thanks to a unified system that intelligently chooses when to deploy either fast, lightweight models for simple queries or more in-depth models for complex tasks. OpenAI also highlights new capabilities such as safer responses, superior coding and writing support, improved voice handling, customizable personalities, and—for paying users—Google app integration.

Apple’s AI strategy appears to be accelerating as it deepens its collaboration with OpenAI even as the company invests in developing its own AI technologies. Notably, a Bloomberg‑sourced report indicates Apple has created a new “Answers, Knowledge and Information” team working on a ChatGPT‑styled engine that can search the web and answer general queries.

For users, the GPT‑5 upgrade means more accurate, responsive Siri interactions, smarter help with text, improved responses from images and screenshots, and overall confidence that Siri can handle tougher questions.
