Apple to Stagger Gemini-Powered Siri Rollout After Testing Snags

Internal testing shortfalls are pushing Apple toward a staged release.

Overview

  • Bloomberg reports that capabilities once targeted for iOS 26.4 in March are being moved to iOS 26.5 in May, with some slipping to iOS 27 in September.
  • Internal testing found slow responses, incorrect query handling, and a bug that cuts off users who speak quickly, with some trials showing unexpected fallback to ChatGPT.
  • Expanded access to personal context across messages and mail is the most likely to be postponed, and voice-driven app intents control is also behind schedule.
  • Engineers are now testing these features in iOS 26.5 builds that include a notice about Siri enhancements and a preview toggle, suggesting a potential limited beta-style release.
  • Apple told CNBC it still plans to launch the overhauled assistant in 2026, with the upgrade built on Apple Foundation Models and Google’s Gemini technology.
