Muse Ember declines 64% of knowledge questions, halving its hallucination rate vs Haiku
ArtificialAnlys · x · 2026-11-10
Artificial Analysis flagged Muse Ember's clear weakness and a surprising upside:
- AA-Omniscience accuracy is just 21.1%, the lowest among similarly intelligent models, mostly because it declines to answer 64% of questions
- But that keeps its hallucination rate at 17.4%, half of Claude Haiku 5.5's
In short, Muse Ember's strategy is "say no when unsure" — weak knowledge coverage but high answer reliability, suited to tasks where a wrong answer is worse than no answer.
