Our latest Open-Source diarization model Community-1 is now available in pyannote.audio 4.0!

Our most significant open-source update brings you faster, more accurate diarization with seamless integration, and more:

• Cleaner speaker assignment: Exclusive single-speaker mode eliminates overlapping conflicts.

• Faster training pipeline: Metadata caching and optimized data loaders reduce training time by 40% while maintaining quality.

• Smarter STT reconciliation: Streamlined timestamp reconciliation means fewer integration headaches.

• Better accuracy: Significant improvements over OSS 3.1, especially with noisy, real-world audio conditions.

• Premium path: Seamless upgrade to pyannoteAI Premium models when you need production-grade accuracy.

How to upgrade: pip install --upgrade pyannote.audio. New features are opt-in; existing code keeps working.

Note: Python 3.10+ required for this version.
