Hi3D v1.0 open-sources 3D refinement

Hi3D v1.0 is a meaningful step toward practical, locally deployable 3D asset pipelines, but its “open-source” label comes with real hardware and licensing caveats.

• –Developers can refine existing meshes rather than relying solely on image-to-3D generation.
• –The pipeline supports 512³, 1024³, and 1536³ refinement passes, enabling a quality-versus-cost tradeoff.
• –V1 generates geometry only; textures, materials, training code, and evaluation tooling are not included.
• –Local inference requires Linux, CUDA, and an NVIDIA Ampere-or-newer GPU; the highest-resolution path was validated on a 96 GB H20.
• –The custom Hi3D license permits commercial use but requires branding and additional licensing above 200,000 monthly users or $1 million in revenue.
