Apple on-device AI (iOS 26+)

Private, no-network generative AI on iPhone/iPad/Mac. This skill routes between the four local runtimes and covers the Foundation Models framework in depth.

• Core ML model loading/prediction, compute units, MLTensor, .mlpackage → coreml.
• OCR, barcode/face/text detection, image segmentation → vision-framework.
• Tokenization, POS/NER tagging, sentiment, word embeddings, on-device translation → natural-language.
• Expose app actions/entities to Siri, Spotlight, and Apple Intelligence → app-intents.
• Fintech note: the system model runs fully on-device — no prompt or user data leaves the phone, which is what makes it usable for balances/transactions. Still treat model output as untrusted (see Safety).
