A20 Pro’s powerful computing power lets the iPhone 18 Pro run a 27-billion-parameter model at twice the speed of its predecessor

Apple’s latest A20 Pro chip is demonstrating its true potential in on-device artificial intelligence. A new real-world test shows that an iPhone 18 Pro powered by the A20 Pro can run a large AI model with 27 billion parameters locally, reaching a generation speed twice that of the previous iPhone 17 Pro. This has sparked renewed interest in the new wave of mobile on-device AI capabilities.
