Hi3D 1.0 (formerly Sparc3D)

Hi3D has open-sourced version 1.0 of its image-to-3D model, the renamed Sparc3D, released 23 October 2026. It refines a coarse mesh into high-resolution geometry conditioned on a reference image, using sparse latents and a self-pruning sparse VAE over up to three passes, reaching an effective 1536³ extraction grid. Training used about two million curated 3D assets. The release includes inference code, weights on Hugging Face, a technical report and a Hugging Face Space; training code is not included. It ships under the custom Hi3D Open License Agreement. The company's hosted v3.0 goes to 2048³ geometry and 8K textures.
