Apple Intelligence's integration with ChatGPT won't utilize the newly released GPT-5 model until iOS 26, iPadOS 26, and macOS Tahoe 26 are released, according to Apple. Currently, Apple Intelligence relies on OpenAI's GPT-4o for tasks like Siri queries and Visual Intelligence features. While the next major software updates are expected to launch in the fall, Apple has not yet confirmed if GPT-5 will be available in the developer or public betas. GPT-5 was released to ChatGPT users on Thursday.
