Meta's Muse Wonder Reaches the Frontier at Opus Prices (October 12, 2026)
On October 12, Meta released Muse Wonder and Muse Wonder Full, its first models aimed at the top tier, built for agents with memory that carries across conversations. On the independent Artificial Analysis index, Wonder Full scores 56 and Wonder 52, behind Claude Opus 5.5 at 58. Wonder costs $4 per million input tokens and $20 per million output tokens on Meta's API, the same as Opus 5.5. Wonder Full is sold only in Muse Code plans at $50 or $200 a month, which default to a mode that lets Meta train on what users submit.
So what
A fourth frontier lab adds leverage in model negotiations, but nothing here is a reason to switch on price or quality. The exposure is data: anyone on your team trying Muse Code should turn off Contributor mode before pasting code or client files, since the opt-out covers only future submissions. Add training defaults to your AI tool approval checklist. Revisit if Wonder Full reaches the API, where Meta says its prices will sit below rivals' top models.
Hype check
Meta's own chart puts Wonder Full ahead on 7 of 14 benchmarks, mostly long coding and legal tasks, while independent scoring ranks it second. One developer's launch-day agent test ran six hours and about $96 without clearing an early game milestone; that is one run, not a benchmark.
Confidence: Established fact — launch, prices and plan terms come from Meta and VentureBeat; relative quality rests on early benchmarks.
