Meta unveiled its Muse Wonder models, its most capable yet, built for agent work in law, finance, health and coding.

Muse Wonder is live on the Meta Model API at $4 per 1M input and $20 per 1M output tokens, with a context window of about 1M tokens.

Muse Wonder Full, the stronger version, is only available in Muse Code on the $50 and $200 monthly plans. Both models add Active Memory, which carries details across chats.

On the Artificial Analysis index, Wonder Full scores 56 and Wonder 52, behind Claude Opus 5.5 at 58. Wonder Full leads coding tests like DeepSWE 1.1 (79.0) and SWE-Marathon (57.5).
