Apple is preparing to bring major artificial intelligence upgrades to the iPhone after falling behind rivals in built-in AI features over recent years. According to Bloomberg’s Mark Gurman, the company is planning a significant overhaul of Siri with the release of iOS 27, expected in September 2026 alongside the iPhone 18. The update will transform Siri into a full AI-powered chatbot, similar to tools like ChatGPT. The AI-powered Siri project has reportedly faced delays and is now scheduled for launch in late 2026. This has put Apple behind competitors like Google and Samsung, which already offer advanced AI tools on their devices.
