Apple has confirmed a significant artificial intelligence overhaul for its virtual assistant, Siri, which is slated to launch in March 2026 alongside iOS 26.4. This fundamental transformation will enable Siri to become a context-aware assistant capable of 'on-screen awareness' and seamless cross-application integration. To power these advanced capabilities, Apple is adopting a unique strategy by partnering with Google to utilize its 1.2 trillion parameter Gemini AI model, running on Apple's Private Cloud Compute to maintain strict privacy standards.
