Muse Wonder

Meta
Verdict

A versatile model, balanced across most use cases.

Overview

Muse Wonder is Meta's generalist model, available only through its paid API, with a million-token context window geared toward code and agentic workflows. Its AA Intelligence Index score (52.4) is solid but unremarkable, and Meta's claimed parity with Opus 5.5 remains unconfirmed. The stronger Muse Wonder Full variant is reserved for Muse Code subscribers and isn't publicly documented. Hosted in the United States with no on-premise option, so data runs through Meta's own infrastructure.
