Meta says Wonder scored 85.6 on MemoryBench and, paired with Muse Code, 68 on Artificial Analysis's coding agent evaluation. Chief AI Officer Alexandr Wang said the company aimed for practical work, not 3D demos, and the model card lists 3D spatial reasoning as a known limitation.","whyItMatters":"The API-tier model Meta shipped scores below GPT-6 Astra and Claude Opus 5.5 on its own composite index, so the practical-work framing and the memory and coding wins carry the launch rather than an overall lead.","webCardHtml":"\u003cp\u003eBoth models are already live. Wonder Full is sold on Muse Code plans at $50 per month or more, and Meta says it reaches subscribers of the personal AI agent app Muse soon.
