Apple will unveil an enhanced version of Siri powered by Large Language Models (LLMs) at WWDC 2024, with this version making its debut in iOS 18. However, according to recent rumors, some new cutting-edge generative AI features might be exclusive to the iPhone 16 models.

Last month, Bloomberg reporter Mark Gurman revealed that Apple is developing a slew of features utilizing generative AI, including a "smarter version of Siri" and new AI functionalities based on LLMs, which will be integrated into iOS 18 and iPadOS 18.

Gurman stated that Apple is still debating whether to confine generative AI processing to devices, deploy it via the cloud, or employ a hybrid approach combining both. Neither side mentioned whether certain AI features would require specific hardware architecture or permeate all devices capable of running iOS 18.

However, according to independent information shared by leaker @Tech_Reve, iOS 18 will bring the company's new LLM to millions of existing devices via cloud-based AI, while AI functionalities on new devices might still be exclusive to the iPhone 16.

Regarding iOS 18 features, Gurman's sources mentioned improvements in interaction between Siri and the Messages app, enabling users to answer complex questions more efficiently and automatically complete sentences. We might also see automatically generated Apple Music playlists and integration with productivity apps like Pages and Keynote, facilitating AI-assisted writing and slide creation. The relationship between this AI integration and new hardware requirements is currently unknown.

Apple is designing new A-series chips for the iPhone 16 series, utilizing TSMC's latest N3E 3-nanometer node. While improvements in efficiency and performance are expected, Apple's AI intentions may bring additional benefits. It's worth noting that TSMC is the sole manufacturer of NVIDIA's powerful H100 and A100 AI processors, which power tools like ChatGPT and are used in most AI data centers.

Rumoredly, all models of the iPhone 16 series will feature an additional button, the purpose of which remains unknown. Internally dubbed the "Capture button," it's a capacitive button located on the same side as the power button, capable of detecting pressure and touch, providing tactile feedback when pressed. While there's no news about its function, it's conceivable it could have unexpected practical AI applications.

Reportedly, Apple allocates $1 billion annually for AI research, with some high-profile executives overseeing development, including Senior Vice President of Software Engineering Craig Federighi, Senior Vice President of Machine Learning and AI Strategy John Giannandrea, and Senior Vice President of Services Eddy Cue.
