Meta Launches Muse Wonder Models, Scoring 56 to Rank Second on Artificial Analysis Index

Meta's new model Muse Wonder (Full) scored 56 on the Artificial Analysis Intelligence Index v4.3.2, ranking second globally—just 2 points behind leader Claude Opus 5.5 at 58—while overtaking GPT-6 Astra. It is the Muse team's largest and most capable model to date, marking Meta's return to the top tier of closed-source model competition.

Confirmed

• Artificial Analysis's official account detailed Muse Wonder Full (max)'s rankings across the ten sub-evaluations of the Intelligence Index: first place in both CritPt (33% weight) and GDP.pdf (33% weight), though with a slim margin—the closest competitor sits at 31-32%; overall, it placed in the top three in six of the ten sub-evaluations.
• A screenshot of the AA Index v4.3.2 shows Muse Wonder (Full) at 56 points alongside/just behind the top spot held by Claude Opus 5.5 (accounts vary slightly; the official page lists it second at 56, with Opus 5.5 at 58).
• Meta's research blog and the AA index page are both live and serve as primary sources.
• A Muse team member announced muse wonder (full) 🍉 as their largest and most capable model yet, saying each release brings huge leaps with accelerating progress: "There are no walls. Superintelligence is coming."

Why it matters

• Muse Wonder closing to within 2 points of the widely regarded SOTA Claude Opus 5.5 and surpassing GPT-6 Astra directly reshapes the competitive landscape among frontier models.
• Topping sub-categories like CritPt and GDP.pdf shows its gains aren't just from overall weighting—useful signal for users who care about specific benchmark dimensions.
• The team's bold claim that "there are no walls, superintelligence is coming" makes whether it can sustain these leaps worth watching.
