Hi3D
Open release of Hi3D v1.0, formerly Sparc3D, for refining a coarse 3D mesh into high-resolution geometry.
The model card says Hi3D v1.0 was released on October 23, 2026. It refines a coarse mesh into high-resolution geometry conditioned on a reference image, at resolutions 512, 1024, or 1536. The project report says it was trained on about 2 million curated 3D assets. Inference code is on GitHub, weights are on Hugging Face, and an online demo is on a Hugging Face Space. It requires Linux, Python 3.10, CUDA 12.0 through 12.5, and an NVIDIA GPU. The 1536 resolution was validated on a 96 GB GPU. The license is the custom Hi3D Open License Agreement 1.0, which is not an OSI license. This is a refinement step, not a full text-to-3D model, and the GPU needs are heavy.
