Overview

• Bloomberg reports Apple signed a formal agreement this week to evaluate a custom Google Gemini model to power parts of the revamped assistant.
• The internally named World Knowledge Answers feature is slated to debut inside Siri with iOS 26.4 as early as March 2026, with potential expansion to Safari and Spotlight later.
• The new interface would return results using text, images, video, and local points of interest, and include AI-generated summaries to condense web content.
• Apple plans to use its own Foundation Models for searching user data and to run third-party models on its Private Cloud Compute to protect privacy.
• The project is led by Apple’s AKI team under senior executives, and while Anthropic and others were evaluated, costs reportedly favored Google as a U.S. judge allowed Apple’s default-search deal with Google to continue.
