# witness-pyannote-seg-mlx
`pyannote/segmentation-3.0` powerset speaker segmentation, converted to a
gate-free MLX safetensors for witness's on-device speaker diarization.
## Upstream attribution
- **Model**: pyannote `segmentation-3.0` (PyanNet powerset segmentation).
- **Authors / source**: pyannote — `pyannote/segmentation-3.0`.
- **License**: MIT (the segmentation-3.0 model weights are MIT-licensed).
## What's in this repo
- `model.safetensors` — gate-free converted weights produced by
`.research/diarization/gen_seg_fixture.py`. Validated to 100% per-frame
powerset-argmax agreement with the upstream export (logits max_abs ≈ 2.5e-5).

*Converted to MLX for [witness](https://github.com/littlebearlabs/witness), an
open-source Rust toolkit for on-device system capture on macOS. Generated by
`.research/diarization/publish_weights.sh`.*
