Evidence claims:
- [upstream_claim] README: high-resolution transformers pretrained on 1 billion human images, published at ICLR 2026; tasks pose (308 whole-body keypoints), body-part segmentation (29 parts), surface normals, pointmaps, human matting. · source: https://github.com/facebookresearch/sapiens2
- [upstream_claim] Six variants 0.1B, 0.4B, 0.8B, 1B, 1B (4K, trained at 4096x3072) and 5B; initial release April 24, 2026; 1B matting model released May 15, 2026. · source: https://github.com/facebookresearch/sapiens2
- [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.
