iPhone 18: 12 GB of RAM and smarter Siri without price increase

The next iPhone 18 must mark a significant leap in Apple's artificial intelligence. According to a KB Securities report, quoted by DigiTimes and passed on by MacRumors, the standard iPhone 18 model will come equipped with 12 GB RAM — a 50% increase over 8 GB of iPhones 15 Pro and 16. The goal is clear: to run Apple's most advanced AI locally, allowing Siri to become more expressive, contextual and reliable, without relying exclusively on the cloud. The good news for the consumer is that unlike previous rumors about possible increases, the price should remain the same as the current line.

Why does iPhone 18 need 12 GB of RAM for local AI?

Large language models (LLMs) require abundant RAM memory to operate locally with fluidity. Currently, only iPhones with higher RAM capacity can perform advanced AI features, such as the most natural Siri and improved diction. With 12 GB, Apple will be able to integrate a model with more parameters directly into the device, reducing latency and increasing privacy — as processing stays on the device. The change also prepares the ground for future features, such as more contextual responses and integration with third-party apps.

How will Siri with local AI be smarter on iPhone 18?

The Siri of iPhone 18 promises voices with more varied intonation and emotion, leaving the current robotic tone. Diction will be more precise, understanding slang, pauses and corrections in real time. Apple has been investing heavily in AI models since the launch of Apple Intelligence, and the increase in RAM on iPhone 18 is a natural step towards democratizing these features. While competitors like Facebook's IA Mode focus on social network search, Apple bets on native integration with the operating system.

IPhone 18 release date: when to wait?

Historically, Apple launches new iPhones in September. The iPhone 18 must follow the same schedule, with an announcement scheduled for September 2026. The KB Securities report, released in June 2026, strengthens confidence in the manufacturer’s plans. The expectation is that the entire line — including the Pro models — will also receive the RAM upgrade, but the highlight is the standard model, which will finally follow the evolution of the AI.
