What is documented about Hi3D v1.0
news checked 2026-10-27Refines a coarse mesh into high-resolution geometry conditioned on an image (geometry only, no texture); trained on about 2M assets. Files: transformer_512 3.68 GB + transformer_1024 3.68 GB + sparse VAE 0.38 GB. Uses Hunyuan3D-2mini for coarse shapes in examples. Parameter count not stated.

Memory · 1 precisionHow much VRAM it needs
Weights plus 20% runtime overhead. For 3d models, activations also depend on resolution, clip length and batch size; the per-GPU estimates below give the practical configuration.
| Precision | Weights | Weights + headroom |
|---|---|---|
| BF16 / FP16estimated | 8 GB | 10 GB |
Cross-checked on Hugging Face Oct 28, 2026: repository read, 7.7 GB of weight files. Method: weights estimated from the parameter count (2, 1 and 0.6 bytes per parameter; the published checkpoint size at its own precision) x 1.2 runtime headroom; short context.
Smallest configuration per GPU · 110 GPUs · cheapest eligible on-demand offer per GPU count, every provider on fileWhat it costs to run, GPU by GPU
The fewest GPUs of one type whose total memory fits the model at short context, priced from the cheapest eligible on-demand offer for exactly that count (45-day window, newest reading per provider), with the next providers beside it. Monthly = 730 hours.
