Apple's iPhone 18 to Feature 12GB RAM for Siri AI, No Price Increase

According to reports from South Korea's KB Securities and DigiTimes, next year's regular iPhone 18 will come with 12GB of RAM to support Apple's most powerful on-device AI model and related Siri features. Apple confirmed during WWDC 2026 that this model enables more expressive Siri voices and improved dictation accuracy. Some sources suggest this plan risks deepening a global DRAM crisis.
