What is TripoSR?
TripoSR (Tripo AI × Stability AI) reconstructs a 3D mesh from one image in under a second on a high-end consumer GPU. MIT licensed. Output meshes are rough — designed as a starting point for a sculpting pipeline, not a final asset. The fastest open 2D→3D in this class.
Pros & cons
Pros
- Sub-second inference on modern consumer GPUs
- MIT license — commercial-friendly
- Tiny model (~1 GB)
Cons
- Output meshes are low-poly and topologically rough
- Single-image only — no multi-view conditioning
