Muse Wonder from Meta | First Impressions

https://arena.ai/agent Meta says its new Muse Wonder Max is at the level of Opus 5.5 and Astra. We put it through dozens of one-shot prompts (3D scenes, animated HTML pieces and front-end design) and compared it with Astra, Opus 5.5, GPT-6.1 Sol, Claude Sonnet 5.5, Fable, Kimi and Mistral, including what each generation cost. The short version: it’s better than Kimi on most tasks, but across one-shot generations it looks closer to GPT-5.6 Sol than to the frontier models Meta compared it with.
