AFM Sandbox is an interactive learning app and developer playground for Apple's Foundation Models framework. Every example runs live on the on-device language model built into your iPhone or iPad, so you can see how the API behaves in real time. LEARN BY RUNNING REAL REQUESTS • 49 hands-on lessons across 12 topics: Meet the Model, Prompting Basics, Streaming, Generation Options, Structured Output (@Generable), Reasoning, Vision, Tools, Transcripts, Profiles, Errors & Feedback, and Under the Hood. • 100+ one-tap examples—from quick basics to creative prompts—or edit any input to test your own ideas. • Every run shows the formatted Result alongside inline live Stats (total time, time to first token, input/cached/output tokens, and model calls), the Raw framework output, and ready-to-copy Swift code that updates as you edit. • Switch between Beginner mode (plain-English explanations) and Developer mode (API signatures, parameter types, and implementation notes). EXPLORE EVERY CAPABILITY • Structured Output: Generate real Swift structs, enums, and arrays with @Generable, @Guide constraints, streaming PartiallyGenerated snapshots, and runtime schemas. • Vision & Multimodal Prompts: Test image understanding, structured receipt/scene extraction, multi-image comparison with ImageReference, and built-in OCRTool & BarcodeReaderTool using 10 built-in sample images or your own photo library. • Tool Calling & Spotlight: Watch the model call Swift functions for weather, dice rolls, unit conversion, and Core Spotlight search, and inspect every tool call in the transcript. • New in iOS 27 APIs: Experiment with DynamicInstructions, @SessionProperty, DynamicProfile lifecycle hooks, editable transcript history, and custom LanguageModel executors. INTERACTIVE AI PLAYGROUND • Chat freely with the on-device model while tweaking settings on the fly. • Switch between 6 built-in Personas (Helpful, Socratic Tutor, Swift Coder, Storyteller, Devil's Advocate, Pirate) or write your own custom system instructions. • Toggle live Swift tools (Weather Lookup, Dice Roller, Unit Converter) and tune Creativity (temperature), Sampling Mode (greedy, top-k, top-p with seed), and response length. 100% ON-DEVICE & PRIVATE • Everything runs locally on your iPhone or iPad. • No accounts, no API keys, no analytics, and no servers. Requires a device with Apple Intelligence turned on, running iOS 27 or iPadOS 27 or later. ## Key features - Interactive learning lessons - Live on-device AI model execution - Structured output generation - Vision and multimodal prompts - Tool calling capabilities - Customizable AI personas - On-device privacy ## Is AFM Sandbox safe?
