Multiple outlets report renewed speculation that Apple’s next base iPhone, the iPhone 18, will ship with 12GB of RAM. The requirement is tied to Apple’s on-device “most powerful” Siri AI model, which is described as needing at least 12GB of unified memory to deliver the company’s most advanced Siri capabilities. Reported features include more expressive Siri voices and improved accuracy for systemwide dictation. Under earlier assumptions, phones with 8GB of RAM—such as the iPhone 17—would not support the full set of Siri AI features when they roll out. \n\nAnalyst reporting cited by these sources points to KB Securities, which says Apple plans to standardize 12GB across the iPhone 18 lineup to avoid excluding customers from the complete Siri experience. The same reporting also says Apple would keep the iPhone 18’s pricing at its current level, despite expected component cost pressure. Another consistent element across reports is Apple’s anticipated launch schedule: Pro models in the fall of 2026 and the non-Pro iPhone 18 arriving months later, in spring 2027. Supplier notes also suggest Apple is seeking more LPDDR5X memory supply for the next generation.
