According to 9to5Mac, Apple said that ChatGPT integration in Apple Intelligence will use the latest GPT-5, starting with iOS 26, iPad OS 26, and macOS 26. Although no release date was given for the update, it is expected to arrive around September or October, based on Apple's rollout of the update alongside new iPhones, which usually occurs in September.
GPT-5 is a new artificial intelligence model that OpenAI introduced today. It offers smarter support and operates faster, including better programming support, improved math and other information. It is also less hallucinatory, thus reducing the generation of fabricated answers.
In addition to Apple products, users can access GPT-5 starting today on ChatGPT, as well as accessing it through Microsoft Copilot.
