Agents in 3d design

Preprint: 3DCodeVerse harness wins 90% of human comparisons against Claude Design

Researchers report a dataset of executable 3D code and a multi-agent harness that checks and revises programs without human feedback. In pairwise human evaluations, both systems were run by Claude Opus 5.5.

Why it matters: It suggests the harness, not only the model, drives 3D output quality; the authors also say fine-tuning on their dataset significantly improves open models' 3D coding.
