Apple’s much-awaited Personalized Siri feature was initially set to debut with iOS 18.4 last month. However, fans will have to wait a bit longer, as the tech giant has announced a delay until next year. Despite this, optimism is brewing among Apple employees who believe that the feature might just be ready for a surprise launch by the end of this year.
In a recent update, insights emerged about how Apple is advancing its artificial intelligence through a mechanism known as Apple Intelligence. According to a Bloomberg report, Apple is utilizing synthetic data to enhance its AI models while maintaining strict user privacy—a core value for the company.
Apple’s unconventional approach of training AI via synthetic data, while unique, has faced some challenges. One key issue is the difficulty the data faces in recognizing trends needed for tasks involving summarization or extended text format, such as drafting emails. To address this, Apple has developed a novel technique that compares synthetic data with a sampling of recent user emails, all the while ensuring that user privacy remains paramount.
To refine their AI model, Apple generates an array of synthetic emails covering commonly found topics. These sample emails, such as an innocuous invitation to play tennis, serve to capture the linguistic and topical dimensions of communication. They’re transformed into embeddings representing these key dimensions and disseminated to a handful of user devices that have consented to share Device Analytics.
These participating devices analyze both synthetic and real user emails, eventually identifying which synthetic embeddings closely match user communication. Employing a privacy measure known as differential privacy, Apple is then able to discern popular synthetic embeddings across devices without knowing who chose what. This process helps Apple generate training data while safeguarding user privacy.
By continually iterating on this process—expanding topics and linguistic nuances like replacing “tennis” with “soccer” for variation—Apple aims to improve email summaries and other text-based features. The forthcoming rollout of these improvements is anticipated in upcoming beta versions of iOS 18.5 and macOS 15.5.
With these advancements, Apple is adamant that the new technology, even in its early stages, holds the promise of understanding user trends more effectively without compromising privacy. Expect further updates as the company seeks to reclaim its position at the forefront of AI technology.
