Apple is opening its on-device AI models to third-party developers through an SDK announced at WWDC 2025.
This move allows integration of native AI models for tasks like text rewriting, image generation, and notification summarization into iOS and macOS apps.
The SDK will provide developers access to foundation models for features such as Visual Intelligence, summarization, and rewriting, enhancing on-device AI capabilities.
Cloud-based AI models will remain restricted to protect user privacy and maintain control over computing costs, but future phases may open up cloud hooks.
