Apple will reportedly bring OpenAI’s latest GPT-5 model to iPhones via iOS 26 update. Here’s how iPhone users can take advantage of its capabilities.

Apple Intelligence will integrate OpenAI's newly launched ChatGPT-5 model when iOS 26 arrives next month, Apple has confirmed (via 9to5Mac).

However, the chat portion of Siri will be mostly the same, so ChatGPT will still be a major part of Apple Intelligence throughout 2026. Apple is reportedly working on a “true modernized, conversational version of Siri,” using a homegrown large-language model, but that isn’t expected to arrive until iOS 27.
