Evidence claims:
- [upstream_claim] README: official PyTorch implementation of 'Human Motion Diffusion Model' with text/action/unconstrained generation, in-between and upper-body editing, training and evaluation scripts, and the faster DiP model; datasets HumanML3D, KIT-ML, UESTC, HumanAct12. · source: https://github.com/GuyTevet/motion-diffusion-model
- [upstream_claim] Outputs: results.npy of xyz joint positions, stick-figure mp4, and via the mesh script SMPL parameters and per-frame .obj meshes; dependencies include SMPL, CLIP, SMPL-X and PyTorch3D with their own licenses. · source: https://github.com/GuyTevet/motion-diffusion-model
- [upstream_claim] arXiv:2209.14916 by Tevet et al., first submitted 2022-09-29; abstract reports state-of-the-art results on text-to-motion and action-to-motion benchmarks. · source: https://arxiv.org/abs/2209.14916
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.
