Python Runtime v1.1.0 (macOS arm64)

What's New in v1.1.0

MPS GPU Acceleration (5-15x speedup)

• Patched PyTorch 2.10.0 with Metal scalar address-space fix (device → constant in c10/metal/indexing.h)
• Pyannote diarization now runs on Apple Silicon GPU via MPS backend
• Automatic MPS detection with CPU fallback

Architecture Change: Scripts Separated

• Python scripts are no longer in the runtime archive
• Scripts (run_diarization.pyc, download_model.pyc) ship with the app bundle
• Script updates = app update only (no re-downloading 240MB runtime)
• Runtime download only needed when Python/PyTorch version changes

Contents

• Python 3.13.11 (arm64)
• PyTorch 2.10.0 (patched for MPS)
• pyannote.audio + speaker-diarization model

System Requirements

• macOS 14+ (Sonoma or later)
• Apple Silicon (M1/M2/M3/M4)
