Apple details how it plans to improve its AI models by privately analyzing user data

Apple has introduced a new approach to enhance its AI models while prioritizing user privacy. This method involves comparing synthetic datasets with real user data samples—such as recent emails or messages—from individuals who have opted into the company's Device Analytics program. Devices determine which synthetic inputs most closely resemble real data and send only a signal indicating the best match, ensuring that actual user data never leaves the device. This allows Apple to refine its AI outputs, like email summaries, without direct access to personal information. ​

The initiative addresses prior challenges Apple faced with training on synthetic data alone, which led to less effective AI performance and delayed features in its Apple Intelligence platform. The new system is being introduced in beta versions of iOS and iPadOS 18.5 and macOS 15.5. Apple continues to leverage its differential privacy strategy, first adopted in 2016, by integrating randomization into datasets to maintain anonymity and protect individual identities. ​

This approach aligns with Apple's commitment to privacy, as the company emphasizes that it does not use customers' private data or their interactions to train its foundation models. Instead, Apple utilizes licensed materials and data from its Applebot web crawler. Even when cloud processing is necessary, Apple ensures that processed data is not stored long-term or accessed by unauthorized entities.

Additionally, Apple provides users with detailed privacy reports showing how their data has been used by Apple Intelligence, further reinforcing its commitment to transparency and user control over personal information.
