 <mark>💡 The 82% size reduction and 55% VRAM reduction means this model now fits on a single 15 GB GPU (e.g. NVIDIA L4, A10, A2 etc.), bringing high-quality text-to-3D generation to individual researchers and end-user hardware.

+Rendered with spherical harmonic lighting, Blinn-Phong specular and ambient occlusion: gray only, no color, so the geometry itself shows. The lace doily is a failure case: INT4 loses the lace pattern.
