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.","whyItMatters":"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.","webCardHtml":"\u003cp\u003eThe 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.\u003c/p\u003e","blueskyPost":"Hi3D V1.0's training set went from 500,000 to 2 million items, so the release is the data as much as the code: whoever trains on it inherits the same slice success rate.","twitterPost":"Hi3D V1.0 ships its weights and a 2 million item dataset. The free generator is the demo; the dataset is the actual release.","threadsPost":"Hi3D V1.0 ships code, weights, and a training set that grew from 500,000 to 2 million items. The free generation on the official site gets the attention, but the dataset is what other teams can build on, and the 90 percent slice success rate is the benchmark they inherit.","newsletterBlurb":"Hi3D has released Hi3D V1.0, formerly Sparc3D, as open source, with source code and model weights available online and free generation on the official site.
