# SAM 3 (ungated copy)

An unmodified copy of Meta's [SAM 3](https://huggingface.co/facebook/sam3) checkpoint in Transformers format, taken from `facebook/sam3` at commit `3c879f39826c281e95690f02c7821c4de09afae7`. It is hosted so that [spintrack](https://github.com/NeLy-EPFL/spintrack) can find a trackball in a video without a Hugging Face login.

Every file except this README is byte-identical to Meta's. `model.safetensors` has SHA-256 `6d06f0a5f84e435071fe6603e61d0b4cc7b40e0d39d487cfd4d67d8cc11cc14a`.

The model is redistributed under the SAM License (`LICENSE`), as its section 1.b.i allows, and its use is governed by that license. Among other terms, publications of research that uses it must acknowledge the use of SAM (section 1.b.ii). For the model itself, its intended uses and how to cite it, see [Meta's model card](https://huggingface.co/facebook/sam3) and the [SAM 3 repository](https://github.com/facebookresearch/sam3).

```python
from transformers import Sam3Model, Sam3Processor

model = Sam3Model.from_pretrained("tkclam/sam3")
processor = Sam3Processor.from_pretrained("tkclam/sam3")
```
