‘We tore it down’: Apple says it built Siri AI ‘from scratch’, but admits this wasn’t the original plan: a first version of its new voice assistant was ready last year



  • Apple has explained why the Siri AI overhaul has taken so long
  • The company initially created an “iterative” version on top of the existing Siri, but it fell short of Apple’s vision.
  • So, Siri was rebuilt from the ground up.

The Siri AI overhaul is finally coming later this year, much later than initially promised, but Apple has now shed some light on why, exactly, it took so long.

In a post-WWDC talk attended by 9to5Mac and TechRadar, Mike Rockwell, the Apple executive who took over leadership of the Siri team last year, explained that, in 2025, the company managed to build a working version of Siri AI “that was kind of an incremental over the original Siri,” but that “we didn’t feel like it was really meeting the vision and the experience that we wanted to make.”

As a result, the team “rebuilt Siri from the ground up, literally tearing it down,” and the end result was “a profoundly more capable Siri.”
