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).
