# SAM 3 — Image / Video / Panorama / Multi-Class Segmentation

Upload an image or video, type up to 5 comma-separated classes, and get a mask overlay you
can preview and download. Panoramas (very wide images) are automatically tiled and stitched.

**Requirements for this Space to run:**
- GPU hardware (T4 or better) — set under Settings → Hardware
- An `HF_TOKEN` secret (Settings → Variables and secrets) with access to the gated
  `facebook/sam3` checkpoint (request access once at
  https://huggingface.co/facebook/sam3)

Built with [SAM 3](https://github.com/facebookresearch/sam3) by Meta. See the repo for
license terms before commercial use.
