The OPENAI GPT-5 model has been put online for most Chatgpt users this week, but many people use Chatppt not via the Openai interface but via other platforms or tools. One of the largest deployments is iOS, the iPhone operating system, which allows users to make certain requests via GPT-4O. It turns out that these users will not have to wait a long time for the last model: Apple will go to GPT-5 in iOS 26, iPados 26 and MacOS Tahoe 26, According to 9TO5MAC.
Apple has not officially announced when these operating system updates will be published on user devices, but these major versions have generally been published in September in recent years.
The new model had already been deployed on other platforms, such as the coding tool Github Copilot via a public overviewas well as Microsoft Co -pilot for general use.
GPT-5 claims to hallucinate 80% less and announce a major rethink of the Openai position of its models; For example, GPT-5 chooses by default automatically if it is necessary to use an optimized model for reasoning based on the nature of the user’s prompt. Free users will have to accept the choice, while paid chatpt accounts allow you to manually choose the model to be used on a quick basis. We do not know how it will work in iOS; Will this stick to the non-introductory mode of GPT-5 all the time, or will he use GPT-5 “(with reflection)”? And if he supports the latter, can users paid by Chatgpt be able to choose manually as they can in the Chatgpt application, or will they be limited to everything that Chatgpt judges appropriate, like free users? We don’t know yet.
