11:01 - Load and run SAM3 image segmentation
import CoreAIImageSegmenter // Load let segmenter = try await ImageSegmenter(resourcesAt: sam3ModelURL) // Use let response = try await segmenter.segment(image: inputImage, prompt: "flower") let mask = response.segments.first?.mask -
11:28 - Load a language model and create a session
import FoundationModels import CoreAILanguageModels // Create model instance let model = try await CoreAILanguageModel(resourcesAt: qwen3ModelURL) // Create session using the model let session = LanguageModelSession(model: model) // Generate response let response = try await session.respond(to: "...") -
12:29 - Generate structured output with @Generable

- 0:00 - Introduction
Overview of Core AI — a new set of technologies that lets you bring advanced on-device AI capabilities to your apps with no server, no cost per token, and no cloud latency.
- 1:16 - App concept: camera-based vocab learning
Introduction to the demo app — an iOS language-learning app where students point their camera at real-world objects to generate vocab cards with translations, example sentences, and segmented images, all running on-device.
- 2:52 - Model discovery
How to define your app's AI requirements — content, language, and device constraints — and select the right models: SAM3 for text-prompted image segmentation and Qwen 0.6B (a 119-language reasoning model) for vocab card generation.
- 7:40 - Getting models with the Core AI models repository
How to use the coreai-models GitHub repository to find popular models with ready-made export recipes — browsing the catalog, running the export script for SAM3 and Qwen, and getting optimized .aimodel files.
- 8:37 - Integration
How to inspect .aimodel files in Xcode (size, platform targets, function signatures, tensor shapes), add the coreai-models Swift package, and select the CoreAILM and CoreAISegmentation libraries as app dependencies.
- 10:55 - Writing the Swift integration code
How to write the Swift code to use both models — loading SAM3 and running text-prompted segmentation, loading Qwen with a single CoreAILanguageModel line, and using the familiar LanguageModelSession API from Foundation Models with structured @Generable output for typed vocab card fields.
- 13:05 - Diagnosing model specialization latency
Using the new Core AI Instruments template to identify that first-run latency is caused by model specialization — the process that compiles a Core AI model for the specific device — and understanding when and how to handle it gracefully.
- 14:40 - Deployment
How to design a deliberate deployment strategy: using a first-run experience to introduce the feature, keeping models out of the app bundle to avoid bloating update size for all users, and triggering on-demand model download via Background Assets only when the user opts in.
- 17:00 - Ahead-of-time (AOT) compilation
How to use the coreai-build command to perform compilation ahead-of-time on your development machine — generating device-architecture-specific compiled model assets that dramatically reduce on-device specialization time during the first-run experience.
- 18:03 - iOS demo
Live demo of the complete iOS experience: fast model preparation with AOT compilation, SAM3 segmenting real objects (rocks, wood, sunflower), and Qwen generating Mandarin vocab cards — with seamless subsequent inferences from the cached model.
- 19:57 - Multiplatform
How the same Swift code runs on macOS with no changes — adding batch processing for folders of photos, stepping up to Qwen3 8B for higher-quality reasoning and pinyin generation, using longer context for curriculum generation, and a live macOS demo processing road trip photos into a full lesson plan.

Summary: Core AI gives you everything you need to build private, multi-platform on-device AI experiences — no server, no cost per token, no cloud latency.
