Suva from Hugging Face launched the LLM 3D Worlds Arena, a Space for ranking 3D worlds generated by different LLMs. It hosts 650+ worlds created by models like GPT 6-Astra, Claude Opus 5.5, and Kimi K3; visitors can walk around each scene and vote.

The launch image shows 14 model entries for the same prompt ("Toy-block industrial town"), built with Three.js or Blender, with visibly different quality. The team is taking suggestions for which models to add next.
