# Rodin Gen-2

![Rodin Gen-2](https://assets.runware.ai/covers/hyper3d-rodin-gen-2.jpg)

Rodin Gen-2 is a 10 billion parameter 3D generation model from Hyper3D built on the BANG architecture. It creates production-ready assets from text prompts or up to 5 input images, with 4x geometry improvement over Gen-1. It supports quad-dominant and raw mesh modes, PBR and shaded materials, configurable polygon counts, T/A pose control, bounding box constraints, and output in GLB, FBX, OBJ, USDZ, and STL formats.
