Muse Wonder

● live
MetaSOTA scope

Live — Oct 12; Meta's most capable model, a new line above Muse Spark; muse-wonder-1.0 on Meta Model API (preview) at $4 / $20 per 1M, $0.20 cached, no long-context premium; 1M ctx, 131K max output; Muse Wonder Full, the stronger variant, is in Muse Code only (Power and Maximum plans); same $4 / $20 as Claude Opus 5.5; Artificial Analysis Intelligence Index (read on AA Oct 12): Wonder 52, Wonder Full 56; Claude Opus 5.5 58 on the same index per Meta's chart; Meta's own table has Wonder Full ahead of Opus 5.5 on 8 of 14 rows (two are Meta-internal: its Personal Superintelligence Index and MemoryBench; DeepSWE 1.1 79.0 vs 74.2, SWE-Marathon 57.5 vs 46.3) and behind on the other 6, including Terminal-Bench 4.0, ProgramBench (59.0 vs 70.5) and the AA index; Meta's launch materials do not use the Watermelon codename, but @kimmonismus, who says he had early access, called the model Meta's 'Watermelon' on Oct 12 after launch, so it was very likely Wonder's codename (Meta has not said). On the board as live since 2026-10-12 — the watchers keep tracking it: lineup changes, pricing moves and deprecations all alert.
