Apple plans to roll out a new on-device AI framework, Core AI, as the successor to Core ML, integrated with iOS 27, iPadOS 27, and macOS 27.

The shift from the term ML to AI reflects a broader naming strategy, while the core goal remains enabling developers to integrate external AI models into apps.

WWDC 2026 is positioned as a major focal point for Apple’s AI strategy, signaling a pivot toward deeper AI integration and enhanced developer tooling.

The details come from Bloomberg Power On newsletter by Mark Gurman, a subscription-based source.

AFM is highlighted for supporting on-device capabilities and offline AI features via the Foundation Models framework.

Apple’s Foundation Models (AFM) are a family of on-device and server-based large language models designed for high performance, efficiency and user privacy, enabling features like summarization, writing, and structured data generation.

The report references related coverage from MacRumors and Bloomberg on iOS 27 features and other Apple product rumors.

Testing is underway for iOS 26.4 with developers and public betas, suggesting several weeks of previews before the first iOS 26.5 beta."

Beyond naming and inclusion in OS updates, no further Core AI details were disclosed at this time.

Core ML remains Apple’s on-device ML framework across iOS, macOS, watchOS and tvOS, supporting models like CNNs and Transformers for image, text and audio analysis.

Previous updates to Core ML and OS releases have emphasized on-device AI performance and Foundation Models, setting the stage for Core AI.

Before iOS 27, Apple is reportedly updating Siri and Apple Intelligence using Google's Gemini AI models, with timing around iOS 26.5 beta discussed in industry reports.
