Muse Wonder Full Isn't the Model You Get on the API

Meta released Muse Wonder and Muse Wonder Full on 12 October. Artificial Analysis scored Full at 56 on its Intelligence Index, two points behind Claude Opus 5.5, and Wonder at 52, but only Wonder is in the Meta Model API, at $4 per million input and $20 per million output, the same as Opus 5.5. Full is 'Not available' on the API and sold only on the $50 and $200 Muse Code plans, and Meta's models page says that setting reasoning effort to max on Wonder doesn't select it. At the Opus price Wonder costs $4.52 per index task, 76% of it input from 7.69 million input tokens per task, and the subscription that carries Full defaults to Contributor mode, where your prompts, code and files train future Meta models.
