## Summary

Chinese 3D generation company Hi3D has open-sourced Hi3D v1.0, which refines a coarse mesh using a reference image of the same object. The model is built on Sparc3D, expanded to about two million curated 3D assets, and requires Linux and an NVIDIA GPU with compute capability 8.0 or newer. Training code is not included, and the release allows commercial use under its own license with a notice requirement above 200,000 monthly active users.
