Model Details
Sapiens, a family of models for four fundamental human-centric vision tasks - 2D pose estimation, body-part segmentation, depth estimation, and surface normal prediction. Our models natively support 1K high-resolution inference and are extremely easy to adapt for individual tasks by simply fine-tuning models pretrained on over 300 million in-the-wild human images. The resulting models exhibit remarkable generalization to in-the-wild data, even when labeled data is scarce or entirely synthetic. Our simple model design also brings scalability - model performance across tasks improves as we scale the parameters from 0.3 to 2 billion. Sapiens consistently surpasses existing baselines across various human-centric benchmarks.

Model Zoo
Note: This repository does not host any checkpoints but contains links to all the model repositories.
We provide checkpoints in three formats:
- original: weights can be finetuned for your use case along with inference.
- torchscript: (inference only) weights ported to torchscript.
- bfloat16: (inference only) for large scale processing, weights ported to bfloat16 (A100 gpu only + pytorch-2.3).
