Overview

  • Apple has set an internal release target of spring 2026 for its long-delayed AI-powered Siri overhaul, expected to arrive with iOS 26.4 around March.
  • The next-generation assistant was previewed at WWDC 2024 and originally slated for fall 2024 but has been postponed multiple times.
  • A hybrid architecture that combined Siri’s legacy framework with a new AI platform experienced roughly a 33 percent failure rate in tests, prompting a ground-up rebuild.
  • John Giannandrea was reassigned from consumer-facing AI projects and leadership of Siri now falls to Craig Federighi and Vision Pro lead Mike Rockwell.
  • Beyond Siri, Apple is developing other AI initiatives including a web-connected chatbot dubbed Knowledge as it seeks to catch up with Google, Microsoft and OpenAI.
