Meta Launches Frontier Model Muse Wonder, Claiming Top-Tier Performance

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.
