Hi3D Open-Sources V1.0 3D Model With 2 Million Training Assets
An open release with published evaluation numbers gives studios, developers, and researchers a shared 3D generation baseline they can run in private environments under the license terms, rather than a closed tool they can only rent.
Reporting from 1 source: ASCII.jp.
Hi3D released Hi3D V1.0, formerly Sparc3D, as open source, publishing the source code and model weights online and offering free 3D model generation on its official site. The training dataset grew from about 500,000 to 2 million items. The model supports up to 1536 cubed effective sparse grid resolution and reached a 90 percent slice success rate in published evaluations.
The release covers the model weights and source code, with a live demo and a Hugging Face repository listed alongside the GitHub page. Hi3D says the curated 3D asset training set grew from about 500,000 to 2 million items before the open-sourcing, and that the team validated the model in production workflows. Published evaluations put it at the highest score for multi-view reproducibility and detail richness, with a 90 percent slice success rate. Fields of use named include 3D printing, product development and e-commerce, industrial design, VR/AR/XR, and animation and video production.
