Muse Wonder FULL from Meta | First Impressions

https://arena.ai/agent Meta just released Muse Wonder and Muse Wonder Full, and in this video we test both on 3D scenes, animated HTML clips and several website builds. We compare them against Claude Opus 5.5, Sonnet 5.5 and Fable 5.1, GPT-6.1 Sol, GPT-6 Astra and Gemini 4 Argon. The Full model is a big step up from the regular Wonder, but it still isn’t at the frontier on design and front-end work. Try the models yourself on Arena.
