→Apple's Siri lead explains the AI Siri delay: they scrapped the first version and rebuilt the entire architecture from scratch
At a closed-door session after WWDC, Apple revealed they had a working prototype last year—an improved old Siri with tool calling. The team decided it fell short of the product vision, so they scrapped it and rebuilt the entire architecture from scratch on a new large model. The new Siri has a standalone app, native multimodal support, privacy built into the foundation, and runs the same system across iPhone, iPad, Mac, Apple Watch, Vision Pro, CarPlay, and AirPods. Mike Rockwell took over Siri management last year.

Apple's Siri lead confirms they scrapped a working prototype last year and rebuilt the entire architecture on a new large model.

This is worth a click because Apple rarely admits to scrapping a working prototype. At a closed-door WWDC session, Mike Rockwell said they had a functional version last year—old Siri plus tool calling—but the team felt it fell far short of the product vision. They chose a different design that required deep architectural changes, tore down the old Siri, and rebuilt from scratch on a new large model. The result: a standalone app, native multimodal support, privacy built into the foundation, and the same Siri running across iPhone, iPad, Mac, Apple Watch, Vision Pro, CarPlay, and AirPods.
I'd discount this a bit—it's Apple's own narrative from a closed session, not a third-party evaluation. "Complete rebuild" sounds dramatic, but the post doesn't give technical specifics: model size, on-device vs. cloud split, latency, or how it stacks up against GPT-5 or Gemini. What's confirmed is Apple chose a rewrite over a patch job and turned Siri from a system feature into a standalone app. That product decision is more informative than the technical details we're missing.
