LibreSAM3DBodyd3-mesh
A mirror of Meta's facebook/sam-3d-body-dinov3 SAM 3D Body checkpoint, hosted
for use with the LibreYOLO mesh task (human body mesh recovery).
This is a mirror, not a new model
The weights are Meta's, unmodified. Nothing here is retrained, distilled or
fine-tuned. The mirror exists so LibreYOLO's mesh task has a stable,
version-pinned source, and so the gate below travels with the weights.

License: read this before requesting access
These weights are not MIT, and they are not covered by LibreYOLO's own MIT
license. They are redistributed under Meta's SAM License, included here as
LICENSE. The SAM License permits redistribution, including
commercially, on the condition that it is passed through: anyone who
redistributes these weights further must do so under the same terms and include
a copy of the agreement.
Restrictions that survive redistribution, summarized but not replacing the text:
- No military or warfare use, nuclear applications, espionage, or guns and illegal weapons.
- Use must comply with applicable Trade Controls and privacy law.
- No reverse engineering or decompiling of the materials.
- Research publications using these weights must acknowledge them.
- Meta may modify the agreement, with changes effective immediately.
Why this mirror is gated
Meta gates the upstream repository with manual approval and rejects requests from comprehensively sanctioned jurisdictions. This mirror instead uses Hugging Face's automatic gated-access flow: users must accept the SAM License and submit the required identity and jurisdiction fields before access, but a repository maintainer does not manually approve each request. It does not claim to reproduce Meta's manual screening; users who require that process should obtain the weights directly from the upstream repository.

The MHR body model is not mirrored here
SAM 3D Body predicts into MHR (Momentum Human Rig). The MHR asset is Apache 2.0 and published ungated by Meta, so LibreYOLO fetches it directly from the upstream release rather than holding a second copy:
https://github.com/facebookresearch/MHR/releases/download/v1.0.1/assets.zip
LibreYOLO caches it automatically via
libreyolo.models.sam3dbody.ensure_mhr_model().
Status
The checkpoint here is the raw upstream artifact under Meta's SAM License. LibreYOLO remains a wrapper around the separately installed upstream implementation; this mirror includes no SAM-licensed model code and no converted LibreYOLO-schema checkpoint.
