The trick: Narrowed Superlative
Meta calls Muse Wonder state-of-the-art.
On the outside Artificial Analysis index its best model scores 56, behind Opus 5.5 at 58, and that best model is not on Meta's API.
Meta says Muse Wonder delivers state-of-the-art performance on personal and professional agentic tasks.
Before you read on. Your call?
TRUE, BUT
56 vs 58
That lead rests on a category Meta defines, partly on its own tests such as FocusBench and MemoryBench. The Artificial Analysis index puts Muse Wonder Full at 56, behind Opus 5.5 at 58, and Wonder Full is only for Muse Code subscribers, not the API.
