Apple Intelligence is a next-generation personal intelligence system unveiled by Apple at its WWDC conference. It's built on a family of generative models, including on-device and server foundation models, a diffusion model for image generation, and a coding model. These models are designed to tackle specific tasks, with the ability to tap into third-party models like ChatGPT for more complex requests. The system is optimized for performance, with an impressive 0.6 milliseconds per prompt token latency on iPhone devices. Apple's approach to training and optimization involves carefully curated datasets, post-training refinement, cutting-edge optimization techniques, and task-specific adaptation. The system has shown strong performance in benchmarks, including human graders preferring its models over open-source and commercial competitors. With a focus on efficiency, performance, and scalability, Apple Intelligence positions the company as a leader in personal AI technology, delivering powerful and personalized AI experiences while prioritizing user privacy and security.
