Apple has rolled out its Foundation Models framework, a core part of Apple Intelligence, with the release of iOS 26, iPadOS 26, and macOS 26 this month. According to the company, the framework enables developers to integrate on-device large language models into their apps, unlocking new features while keeping user data private and ensuring offline availability. Apple also says inference is performed free of cost, reducing the need for server infrastructure.
Susan Prescott, Apple’s vice president of Worldwide Developer Relations, said early adoption has been strong. “From generating journaling prompts that will spark creativity in Stoic, to conversational explanations of scientific terms in CellWalk, it’s incredible to see the powerful new capabilities that are already enhancing the apps people use every day,” she said.
Apple highlighted several examples across app categories. In health and fitness, SmartGym reportedly lets users describe workouts in natural language and converts them into structured routines, while Stoic introduces journaling prompts based on recent entries, processed fully on device. Other apps including SwingVision, 7 Minute Workout, Gratitude, and Train Fitness are said to be delivering personalised coaching and summaries through the framework.
Education apps such as CellWalk, Grammo, and Platzi are claimed to provide conversational explanations of scientific or grammar terms, generate new practice questions, or answer lesson-specific queries. Meanwhile, productivity and creativity tools like Stuff and VLLO are said to benefit from task automation and video editing suggestions powered by Apple Intelligence.
Apple states that the Foundation Models framework is tightly integrated with Swift, providing guided generation and tool calling. It is available now on Apple Intelligence-compatible devices, with beta support for nine languages including English, French, German, Japanese, and simplified Chinese.
