Apple is developing an AI-powered web search tool for Siri, internally codenamed World Knowledge Answers, aiming to provide general search information akin to ChatGPT. This feature will initially be integrated into Siri, with potential future expansion to Spotlight and Safari. The tool will support text, photos, and video queries, summarizing search results for clarity. This enhanced Siri, powered by a rebuilt architecture using large language models, is slated for release in 2026, likely in an iOS update. The new Siri features three core systems: a planner, a search system, and a summarizer. Apple is reportedly in discussions with Google to utilize a custom Gemini AI model for some summarization tasks. They are also testing Anthropic and in-house models for planning functionalities. Apple's own Foundation Models will handle user data searches to ensure privacy. Beyond web search, Siri will gain personalization, allowing it to use personal data like emails and messages to assist users. It will also gain the ability to interact with on-screen content and perform actions within apps. Later in 2026, Siri will receive a visual redesign and a health feature intended to support a paid wellness service.
