Apple brings a fully revamped Siri built on Google's Gemini, but not to the EU
Apple shipped its fully rebuilt Siri running on Google's Gemini models with iOS 27, initially excluding the EU and China over regulatory hurdles.
Apple released 'Siri AI' as an English beta within iOS 27, iPadOS 27, macOS 27, watchOS 27, and visionOS 27, built on Google's Gemini models running partly on-device and partly through Private Cloud Compute. The rollout excludes the EU and China at launch due to regulatory requirements, with French, Japanese, Korean, Portuguese, and Spanish support due next month. Early reviewers call it a step forward but report failures on personal-context queries and occasional hallucinations. Siri integrates with third-party apps like WhatsApp and Audible, with Outlook, Notability, and Tripsy coming later.
