Apple is expected to launch all the iPhone 18 series models with 12GB of RAM, including the standard iPhone 18, according to a report. This is said to allow Apple’s most advanced AI foundational models to run on the rumoured handset, consequently widening the Siri AI adoption and increasing the demand for the upcoming iPhone 18 series handsets. While most AI features will be available on iPhone 15 Pro and later models, the company’s most advanced AI features will not be available on handsets that feature RAM lower than 12GB. Hence, only the iPhone 17 Pro, iPhone 17 Pro Max, and iPhone Air will be able to run the new powerful AI models. Meanwhile, the standard iPhone 17 model ships with 8GB of RAM.
