Apple opens rebuilt Siri AI to everyone in iOS 27 public beta

Apple made its long-awaited Siri overhaul available to all users through the iOS 27 public beta, per TechCrunch. The rebuilt assistant runs on Apple's on-device Foundation Models and Private Cloud Compute infrastructure — the latter reportedly developed with help from Google's Gemini — and introduces a dedicated Siri chat app that turns the assistant into a conversational surface rather than a command line.

The release is significant because Apple's Siri revamp had been repeatedly delayed, becoming a symbol of the company lagging on generative AI. Shipping it to the public beta — even if still beta — signals Apple believes the privacy-preserving architecture (on-device for sensitive tasks, Private Cloud Compute for heavier lifting) is ready for broad use. The dedicated chat app is a notable UX shift, acknowledging that users now expect an open-ended assistant they can converse with, not just trigger.

The Google/Gemini involvement in Private Cloud Compute underscores how even Apple, fiercely protective of its stack, leans on outside frontier models where its own aren't sufficient — a pattern echoed by the China/Qwen deal the same week. The caveat is that beta quality and real-world reliability will determine whether this repairs Siri's reputation or extends the narrative of Apple playing catch-up.
