Siri's Two-Phase Transformation

Apple's approach to upgrading Siri involves a strategic two-phase rollout. The first major enhancement will arrive with iOS 26.4 in March or April 2026, delivering core functionality improvements including screen awareness, personal context understanding, and cross-app action capabilities

The iOS 26.4 update will introduce a sophisticated large language model foundation for Siri, reportedly leveraging Google's Gemini model in a customized implementation. This represents a significant departure from Apple's current 1.5 billion-parameter model, with the new system expected to feature substantially more parameters for enhanced understanding and response capabilities

Following the functional overhaul, iOS 27 will introduce Siri's visual redesign. Gurman reports that Apple has tested making Siri resemble the Finder's icon, giving the assistant a "visual personality to make it feel lifelike"

Health+ Service Launch

The most significant addition may be the introduction of Health+, a comprehensive AI-powered health service integrated into the revamped Health app. This service will feature an AI agent designed to help users manage their health through personalized coaching, curated educational content from health experts, and advanced nutrition tracking capabilities

Apple's partnership with Google for Siri's underlying AI model represents a significant shift, with reports indicating the company will pay approximately $1 billion annually for access to Google's AI technology.
