Choosing a Model

Consider these factors:

Speed vs Accuracy: Smaller models are faster but less accurate. Larger models are more accurate but slower.

Language needs: If you only use English, Parakeet v2 offers the best speed/accuracy ratio. For multiple languages, WhisperKit models are more versatile.

Storage space: Models are downloaded and stored locally. Larger models require more disk space.

Hardware: More powerful Macs can run larger models more efficiently.

Managing Models

  1. Open Dicta settings
  2. Navigate to Models
  3. Download your preferred model(s)
  4. Select the active model

You can have multiple models downloaded and switch between them as needed. Delete unused models to free up disk space.

Model Performance

All models run 100% on-device. Performance depends on your Mac’s hardware:

  • Apple Silicon Macs: Excellent performance with all models
  • Intel Macs: Good performance with smaller models, larger models may be slower
