What Meta announced

Meta introduced Muse Wonder and Muse Wonder Full on October 12. Wonder is available through the Meta Model API and Muse Code; Wonder Full is available to Muse Code subscribers. Meta says a broader rollout inside Muse will follow, beginning with subscribers. The announcement does not promise that everyone can select both versions in the consumer app today.

What the outside check adds

Artificial Analysis published its own evaluation the same day. Both tested versions improved on its Muse Spark 1.3 comparison in Intelligence Index v4.3. That is evidence about the evaluator’s tasks and settings, not a universal ranking of everyday assistants.

Before you try it

Check the exact variant, product, and charging rules. A developer API and a subscription app are different ways to access a model. We have not run either Wonder version; this briefing combines the provider’s availability information with the evaluator’s published results.
