Rated as Muse Spark 1.2 (xHigh) (xhigh effort); Muse Spark 1.1 as muse-spark-1.1. Some were rated at different settings; ratings on one arena share one scale, so the difference still reads directly. Text, WebDev and Vision ratings come from people voting between two anonymous answers; Text and Vision are style-controlled, as on arena.ai. Agent is Arena's separate score for real agent sessions, on its own scale. Not rated on Document, where Muse Spark 1.1 is. Data: Arena (arena.ai), CC BY 4.0.
