At the 2024 Worldwide Developers Conference, Apple announced a significant advancement in AI technology with the introduction of Apple Intelligence, deeply integrated into iOS 18, iPadOS 18, and macOS Sequoia. This new system incorporates a series of highly sophisticated generative models designed to enhance user experience across Apple devices by performing tasks that adapt in real-time to the user’s needs.
Core Models Powering Apple Intelligence
Apple Intelligence is built on two primary types of models: a compact, ~3 billion parameter language model that runs directly on devices, and a more extensive server-based model that leverages Apple’s private cloud compute capabilities. These models are engineered to handle specific tasks like writing assistance, summarization, and image creation, tailoring their responses based on the context of the user’s activity.
On-Device vs. Server-Based Models
The on-device model offers fast, efficient, and private processing, ensuring user data never leaves the device. This model is ideal for quick interactions that require immediate feedback, such as rewriting texts or generating email responses. In contrast, the server-based model, which runs on Apple silicon servers, is used for more complex processing tasks that can benefit from greater computational power while still prioritizing user privacy.
Specialized Models for Developers and Users
Apart from these foundational models, Apple has developed specialized models to cater to different needs. These include a coding model integrated within Xcode to assist developers and a diffusion model designed for creative tasks like generating custom images in the Messages app. These models demonstrate Apple’s commitment to providing a broad range of AI capabilities that support both everyday users and developers.
Responsible AI Development at Apple
Apple’s approach to AI emphasizes responsible development and operation. The company adheres to a strict set of AI principles, focusing on user empowerment, representation, thoughtful design, and privacy protection. These principles ensure that the AI tools and models developed by Apple not only enhance functionality but also maintain ethical standards and user trust.
Technical Innovations and Optimization
Apple’s models are trained using the AXLearn framework on an array of high-efficiency platforms. This training includes techniques like data parallelism and Fully Sharded Data Parallel (FSDP) to manage extensive data sets efficiently. Post-training, models undergo optimization to enhance their performance on devices, applying techniques like low-bit palletization to balance power, memory, and speed.

Adapting to User Needs
One of the most innovative aspects of these models is their ability to adapt through “adapters” — small modules inserted into the model to fine-tune responses based on specific tasks. These adapters can dynamically alter the model’s behavior, making it versatile across different applications without compromising the core model’s integrity.
Conclusion
With the rollout of Apple Intelligence, Apple is setting a new standard for what smart devices can do, powered by a foundation of advanced, responsibly developed AI models. These models are not just enhancing the way devices operate; they are transforming how users interact with technology, making everyday tasks easier and more intuitive. This is just the beginning, and Apple is excited to see how its users will leverage these capabilities to enhance their digital experiences.
TL;DR: Apple Intelligence – A Leap in On-Device AI
At the 2024 WWDC, Apple unveiled Apple Intelligence, a major advancement in AI that’s integrated into iOS 18, iPadOS 18, and macOS Sequoia. This suite includes both on-device and server-based models, enabling advanced AI capabilities directly on iPhones, iPads, and Macs. Key highlights include:
- On-Device and Server-Based Models: Apple Intelligence utilizes a ~3 billion parameter language model for on-device processing and a more extensive server-based model for complex tasks, ensuring user privacy and data security.
- Specialized AI Capabilities: Features range from enhanced writing assistance and creative image generation to a smarter Siri and third-party app integration via the updated App Intents framework.
- Privacy-Centric Infrastructure: The new Private Cloud Compute setup uses Apple Silicon servers that anonymize user data, ensuring it remains secure and private. These servers have no permanent storage and are designed for maximum transparency and security.
- Strategic AI Development: Apple has developed multiple models tailored to various needs, including a focus on a powerful on-device model discussed by John Giannandrea, Senior Vice President for Machine Learning and AI strategy at Apple.
- OpenAI Collaboration: An optional OpenAI ChatGPT-4o layer is available, adding versatile AI interaction capabilities.
