Apple debuts 'Siri AI' and Core AI on-device framework at WWDC, powered partly by Google

Apple used its WWDC keynote to reboot Siri after years of criticism. 'Siri AI' is an entirely new version built on a rebuilt architecture for enhanced conversational ability, personal context understanding, and broad world knowledge, deeply integrated across iPhone, iPad, Mac, and Apple Vision Pro with expanded Visual Intelligence and a dedicated app to review past conversations.

The most striking disclosure is that Siri AI is powered partly by Google-built models — a notable concession for a company that prizes vertical control. Alongside it, Apple introduced Core AI, an on-device framework for running full-scale LLMs optimized for Apple silicon's unified memory and Neural Engine, and Xcode 27 gained agentic coding via Anthropic's Claude Agent and OpenAI's Codex.

Competitively, Apple is racing to close a gap that rivals opened with multimodal assistants from Google and OpenAI. Leaning on Google for the heaviest lifting lets Apple ship a capable assistant quickly while positioning Core AI as its long-term on-device moat. The Wall Street Journal flagged that memory constraints remain a hard ceiling despite Apple's roughly $4.5T valuation, and developers reacted with both excitement at Core AI and unease over Apple's reliance on a direct search-and-AI competitor. Features are available for developer testing as of June 9, with a public beta expected later this year — leaving open how much of the experience runs locally versus calling out to Google's cloud.
