Choosing the right model

​
Precision-2

Best for: Startups, SMEs, and enterprises who need the state-of-the-art in speaker diarization accuracy and advanced features like voiceprints and speaker identification.
Self-hosted options for Precision-2 are available on Enterprise plans.
Typical use cases: phone call analytics, meeting transcription with speaker attribution, video dubbing and timestamp-critical workflows, building training data for voice assistants, and more. Advanced features:
  • Speaker identification with voiceprints: Identify known speakers in your audio using pre-enrolled voiceprints
  • Exclusive diarization mode: Returns speaker diarization where only one single speaker (the most likely to be transcribed) is active at a time, making STT reconciliation easier
  • Flexible speaker count control: Set minSpeakers, maxSpeakers and numSpeakers parameters for any number of speakers
  • Human-in-the-loop correction: Use confidence scores to help streamline manual correction processes

​
Community-1 (hosted)

Best for: Teams who want the open-source model without managing infrastructure Typical use cases: Prototyping, low-volume production workloads, testing and validation Key Benefits:
  • Cost efficiency: hosted at cost, ideal for experimentation and low-volume workloads
  • No infrastructure management: Focus on your application while we handle the deployment
  • Easy migration: Start with hosted Community-1 and upgrade to Precision-2 when needed
  • Same powerful model: Access the same Community-1 model through our API without setup complexity

​
Community-1 (self-hosted with pyannote.audio 4.0)

Best for: Researchers, developers, and personal hobby projects who want full control over their diarization models and workflows. Typical use cases: Academic work, product-iteration, prototyping, and custom diarization deployment (e.g., dataset-specific fine-tuning or custom reconciliation with STT). Key Benefits:
  • Best open-source speaker diarization model available - outperforms pyannote.audio 3.1 across all key metrics
  • Open-source flexibility: Full transparency into model weights and code allowing local and offline training and inference.
Trade-offs:
  • Lower accuracy compared to Precision-2
  • No support for advanced features like speaker identification and voiceprints
  • Requires deploying the model on your own infrastructure

How to specify a model in diarization requests

When making a diarization request, you can specify which model to use using the model parameter: 
curl -X POST "https://api.pyannote.ai/v1/diarize" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://files.pyannote.ai/marklex1min.wav",
    "model": "precision-2"
  }'
By default, if you do not specify a model, the API will use the Precision-2 model.

​
Switch between models

You can easily switch between models by changing the model parameter:
  • "model": "community-1" for Community-1
  • "model": "precision-2" for Precision-2
Note: Speaker identification and voiceprint features are not available for Community-1 models. These advanced features are exclusive to Precision-1 and Precision-2.

​
Compare results between models

To compare performance between models on your specific data:
  1. Process the same audio file with both models
  2. Compare the diarization results
  3. Evaluate which model provides better accuracy for your use case
