Apple unveiled Apple Intelligence at WWDC, introducing generative AI features like email rewriting and custom emoji creation for iPhone, iPad, and Mac. Emphasizing privacy, Apple detailed its on-device approach and use of proprietary AI models trained without private data. By optimizing for power efficiency and size, Apple ensures deep integration of AI into its devices while keeping data secure. Using adapters, Apple fine-tunes models for specific tasks like text summarization and artwork generation. Utilizing Neural Engine in Apple Silicon, the company speeds up AI responses. For complex tasks, Apple sends requests to Private Cloud Compute (PCC) servers, ensuring end-to-end encryption and data deletion post-request. While competitors also offer AI solutions, Apple sets itself apart with a strong focus on data privacy. By balancing local and cloud processing, Apple Intelligence aims to provide advanced AI capabilities while safeguarding user data.
