SceneWorks/sam3-mlx

A redistribution mirror of facebook/sam3 (Segment Anything 3) for download-on-first-use by the SceneWorks macOS worker.

The native-MLX (Rust mlx-gen-sam3) SAM3 segmenter loads the stock checkpoint directly — no conversion — and drives text-concept Promptable Concept Segmentation ("person") for the Replace-Person person-track pipeline (epic 4910). This mirror exists only so the app can fetch the weights without the gated facebook/sam3 access flow.

Files

  • model.safetensors — the SAM3 checkpoint (~0.9B params, F32), byte-identical to facebook/sam3.
  • tokenizer.json — the CLIP-H text tokenizer used for the concept prompt.
  • LICENSE — the Meta SAM License (included as required by the license; it governs use of the Materials).

License

These weights are © Meta and distributed under the SAM License (see LICENSE). This mirror redistributes them unmodified under that license. Refer to the original facebook/sam3 model card for intended use, capabilities, and limitations.
