SapiensID (wb4m) — JAX/Equinox weights
Converted weights for SapiensIdEqx, a JAX/Equinox re-implementation of SapiensID: Foundation for Human Recognition (Kim, Ye, Su, Liu and Liu, CVPR 2025, arXiv:2504.04708, https://github.com/mk-minchul/sapiensid).

The port reproduces the reference forward to 1 − cos 1.79e-12 on the 4096-d embedding, gated at 56 seams end to end on CPU and GPU. Inputs are an image plus caller-supplied body keypoints and foreground mask; the upstream aligner (YOLOv8 / OpenPose) is not part of this port.
Use
from sapiensid_eqx.model import SapiensId
model = SapiensId.from_pretrained("sapiensid_wb4m.eqx")
No PyTorch is needed to load or run these weights.
