Apple recently unveiled details about Apple Intelligence, their proprietary AI system, which has caused some confusion. Contrary to popular belief, Apple is not merely using OpenAI’s technology but has developed its own innovative AI models. These models can run directly on devices like iPhones, iPads, and MacBooks, as well as on their cloud servers, providing users with a highly personalized AI experience.

Apple’s approach focuses on personal intelligence rather than world knowledge. This means their AI is designed to assist with everyday tasks by leveraging the personal data available on Apple devices. The system includes multiple generative models fine-tuned for specific user experiences, such as writing and refining text, summarizing notifications, creating playful images for conversations, and taking in-app actions to simplify interactions across apps.

The core of Apple Intelligence comprises two main models: a 3 billion parameter model that runs on-device and a larger cloud-based model for more intensive tasks. These models are part of a broader family of generative models, including a coding model for Xcode and a diffusion model for visual expression in apps like Messages.

Apple emphasizes responsible AI development, ensuring their models are highly secure, private, and free from biases. They use a combination of licensed and publicly available data for training, with strict filtering to remove personal and low-quality content. Their training pipeline includes innovative techniques like rejection sampling fine-tuning and reinforcement learning from human feedback.

Optimization is a key focus, with Apple using advanced techniques to ensure their models run efficiently on both devices and servers. This includes low-bit parallelization and the use of Laura adapters for fine-tuning without altering the base model’s parameters.

Apple’s models have shown impressive performance in human evaluations, particularly in summarizing emails and notifications. They also excel in safety, with low harmfulness scores compared to other models like GPT-4 Turbo. Overall, Apple aims to integrate these AI capabilities deeply into their ecosystem, providing users with intelligent tools that enhance their daily interactions with their devices.

Matthew Berman discusses these developments, highlighting Apple’s unique approach and its potential to revolutionize personal AI applications. He emphasizes the importance of having AI models that can accomplish real tasks for users, making everyday interactions more efficient and intuitive.
