Meta's Muse Wonder 1.0 Enters PINNACLE Top Ten, Beating Claude Opus 5.5 and GPT-6
ryanshrout · x · 2026-10-15
Signal65's PINNACLE benchmark shows Meta's new flagship agent model Muse Wonder 1.0 breaking into the top ten, ranking above Claude Opus 5.5 (both effort levels), GPT-6 Sol max, and Grok 4.6 — a 1.5x step over its predecessor Muse Spark 1.3.
Key numbers:
- 33% fewer weighted errors than Spark, median rounds down from 32 to 19, 49% fewer output tokens per correct answer
- 99.6% completion on multi-step enterprise jobs, 97.6% on the 128K retrieval corpus, 0.0% fabrication — level with the best on the board
- At Meta's $4/$20 list rate, $1.70 per correct task — 1.9x Spark and 5.6x GPT-6.1 Sol max
The report notes the only thing keeping Muse Wonder 1.0 off the cost frontier is its price, which Meta can change at will. Patrick Moorhead asks: is Meta AI the biggest comeback of the past six months?
