OpenAI Launches GPT-5 with Major Upgrades — Coming Soon to iPhones and Apple Devices
OpenAI has officially rolled out GPT-5, its most advanced AI model to date, promising major improvements over previous generations in reasoning, accuracy, and versatility. The new model has already replaced GPT-4o as the default in ChatGPT and is expected to make its way to Apple devices — including iPhones, iPads, and Macs — with the release of iOS 26, iPadOS 26, and macOS Tahoe 26, according to a report by 9to5Mac.
Apple already integrates ChatGPT into its Siri voice assistant for handling complex queries and generating detailed responses. Until now, Siri has been using GPT-4o to manage these requests, but with GPT-5 taking over, users can expect more refined and capable AI responses. If the report holds true, GPT-5 could start rolling out to Apple devices as early as next month — just in time for the anticipated launch of the iPhone 17 series and Apple’s annual software update cycle.
How GPT-5 Powers Apple Intelligence
GPT-5 will continue to serve as the backbone for various AI features under Apple Intelligence — Apple’s suite of AI tools embedded across its ecosystem. Here’s how users will see GPT-5 in action:
1. Enhanced Siri Responses
Siri will use GPT-5 to handle more complex questions, including those involving photos, files, or detailed contextual understanding — delivering faster, smarter answers.
2. AI-Powered Writing Tools
Users will be able to access GPT-5’s capabilities for proofreading, rewriting, and summarizing text within both Apple’s native apps (such as Notes, Mail, Messages, and Pages) and supported third-party apps.
3. Visual Intelligence Integration
Leveraging the device’s camera, GPT-5 will also assist in analyzing real-world visuals — helping users gather information about their surroundings in real time.
What’s New in GPT-5?
OpenAI claims GPT-5 offers significant upgrades in areas such as coding, writing, reasoning, and health-related queries. The model is also designed to reduce hallucinations — false or fabricated information — and is less likely to provide overly agreeable or biased responses.
In terms of architecture, GPT-5 introduces two specialized components: the Efficient model and the GPT-5 Thinking model. These are now automatically selected in real time through a smart routing system, eliminating the need for users to manually choose the best model for their task — a first for ChatGPT.
While it’s not yet clear exactly how this intelligent routing system will work on Apple devices, it’s likely that the improved reasoning and dynamic model switching will integrate seamlessly into Apple Intelligence features over time.
