TripoSR

TripoSR is a fast single-image-to-3D reconstruction model from VAST AI Research (with Stability AI collaboration): one photo in, a textured 3D model out in under a second on a capable GPU.

It builds on the LRM (Large Reconstruction Model) line of research — feed-forward 3D reconstruction without per-object optimization — which is what makes it fast enough for interactive use.

The repo is a compact, pip-installable inference stack with clear requirements (Python 3.8+, CUDA, PyTorch), so it drops into existing 3D tooling; the approach is documented in an arXiv paper.
