Siri AI taps Google Gemini LLM technology, with future development focused on deep third-party app integration

DIGITIMES has observed that Siri AI is built around four core layers - devices, models, reasoning and applications - and is designed to transform Siri from a voice assistant into an AI agent capable of executing tasks. Its device layer spans Apple’s full product lineup, from iPhone and MacBook to Vision Pro, giving it broader device coverage than those of Google, Samsung Electronics and Xiaomi. Although Apple Foundation Models (AFM) are refined through knowledge distillation and fine-tuning with Gemini, Apple continues to rely on private cloud computing for its cloud-based models and places strong emphasis on user data privacy. In addition, Siri AI’s application layer provides deep app integration and can automatically execute multi-step tasks. This capability represents Siri AI’s key technical advantage and is likely to be a core source of competitiveness in the emerging AI agent race.
