AI Song Detector

This changelog documents notable updates to the Vobile AI Song Detector API, including new features, improvements, and model attribution enhancements.

v6 - May 22, 2026

Improved:

  • Further reduced false positives in challenging edge cases.

v5 - April 16, 2026

Added:

  • Introduced new model attribution classifier: Google Lyria.

Improved:

  • Increased detection accuracy, especially for ElevenLabs and Boomy songs.

v4 - February 24, 2026

Improved:

  • Improved model attribution accuracy.
  • Increased overall detection accuracy, with the focus on reducing false positives in challenging edge cases.

v3 - January 28, 2026

Added:

  • Introduced two new model attribution classifiers: Mureka and Sonauto.
  • The model attribution classifier supports a defined set of platforms listed above. Detection of AI-generated music is broader and not limited to these platforms. In such cases, predicted_model may be null.

v2 - January 7, 2026

Added:

  • Model attribution classifier to identify which model most likely generated the queried song, when the detector has strong attribution confidence.
  • New response fields:
    • predicted_model (string)
    • predicted_model_score (float)
  • Expanded attribution coverage with targeted improvements for ElevenLabs and Boomy, while maintaining broad attribution across other leading AI music generators.

Improved:

  • Higher detection accuracy: internal evaluation shows an estimated \~10% relative lift versus v1 (varies by content type, genre, and audio quality).

v1 - December 1, 2025

Added:

  • Initial release of the Vobile AI Song Detector API.
  • Broad support across major AI music generation platforms.
  • Per-request confidence scoring via ai_score.
