OpenAI’s GPT-5 mannequin went reside for many ChatGPT customers this week, however numerous folks use ChatGPT not via OpenAI’s interface however via different platforms or instruments. One of many largest deployments is iOS, the iPhone working system, which permits customers to make sure queries by way of GPT-4o. It seems these customers will not have to attend lengthy for the most recent mannequin: Apple will swap to GPT-5 in iOS 26, iPadOS 26, and macOS Tahoe 26, in response to 9to5Mac.
Apple has not formally introduced when these OS updates will likely be launched to customers’ gadgets, however these main releases have sometimes been launched in September lately.
The brand new mannequin had already rolled out on another platforms, just like the coding instrument GitHub Copilot by way of public preview, in addition to Microsoft’s general-purpose Copilot.
GPT-5 purports to hallucinate 80 p.c much less and heralds a significant rework of how OpenAI positions its fashions; for instance, GPT-5 by default routinely chooses whether or not to make use of a reasoning-optimized mannequin primarily based on the character of the person’s immediate. Free customers must settle for regardless of the selection is, whereas paid ChatGPT accounts permit manually selecting which mannequin to make use of on a prompt-by-prompt foundation. It is unclear how that can work in iOS; will it follow GPT-5’s non-reasoning mode on a regular basis, or will it make the most of GPT-5 “(with pondering)”? And if it helps the latter, will paid ChatGPT customers have the ability to manually choose like they will within the ChatGPT app, or will they be restricted to no matter ChatGPT deems applicable, like free customers? We do not know but.
