What this measures

How smart is the assistant at the core reasoning, knowledge, and generation tasks people actually throw at it? Frontier benchmark standing, but weighted toward real assistant quality rather than leaderboard maxing.

What moved this grade
  1. Apple

    Siri, rebuilt: conversational and “profoundly more capable”

    “Siri is now a profoundly more capable assistant, more conversational, so you can go back and forth like never before and get detailed, engaging answers.”

    The personal-context Siri Apple promised back in 2024 finally ships in iOS 27, with a new, customizable expressive voice and a major jump in system-wide dictation accuracy. It is the most consequential Siri change in a decade, though the real-world quality only proves out as iOS 27 reaches devices this fall, so we move the grades with a verification caveat rather than to the top of the field.
