Hi3D announced that its V1.0 AI 3D model – previously called Sparc3D – is now open source. The code and model weights can be downloaded from the Hi3D website and used for free. The model was trained on about two million curated 3D assets and can reconstruct geometry at up to 1536³ sparse‑grid resolution. In tests it achieved the highest multi‑view fidelity scores and a 90% slicing success rate. The release also cuts credit consumption by more than half, lowering costs for creators.

## The facts

- Release date: Oct 23, 2026
- Training data grew from ~500,000 to 2,000,000 3D assets

## Why it matters

Developers and small studios can now access a high‑quality, production‑validated 3D generation model without paying for licenses or cloud credits.
