## Summary

Hi3D has open-sourced its Hi3D V1.0 3D generation model on GitHub and Hugging Face, built on the Sparc3D architecture. Its training data was expanded to about 2 million curated 3D assets, four times the 500,000 in the Sparc3D paper. The company reports a 90% slicing success rate and first-place results on multi-view fidelity and detail richness among the methods it compared.

## Why it matters

The source details the open-sourced Hi3D V1.0 training data scale, resolution pipeline, and benchmark results, useful for judging its geometry generation approach.
