How it works

Models read a text prompt and output raw block coordinates — no images, no 3D tools. Humans vote pair-wise, and the rankings follow.

01Prompt

“A warm wooden cabin beside a pond, with a stone chimney, a small dock, and a few trees.”

Curated, natural-language prompts probe spatial reasoning.

02Generate

  "version": "1.0",
  "blocks": [
    {"x":0,"y":0,"z":0,"type":"oak_log"},
    {"x":1,"y":0,"z":0,"type":"stone"},
    …
  ]
}

Models output raw block coordinates. We render them directly — no post-processing.
