Deezer

In-house detection of fully AI-generated music

Deezer built a tool to detect fully AI-generated tracks and keep them out of recommendations

WorkingCompany's own claimOfficial ↗

Problem

Music generators such as Suno and Udio let anyone produce tracks in bulk. Deezer received about 10,000 fully AI-generated tracks a day in January 2025, around 10% of its daily deliveries, and some of the streams on such tracks were fraudulent.

Approach

Deezer developed its own detection tool, which finds the artifacts that generation models leave in audio and can help identify which model made a track. It does not need a separate training set for each model. Deezer filed two patent applications in December 2024. The tool supports a tagging system that labels fully AI-generated music and excludes it from algorithmic and editorial recommendations.

Results

10,000fully AI-generated tracks delivered to Deezer per day in January 2025, about 10% of daily deliveries, per DeezerCompany's own claim[1]
99.8%stated accuracy of the detection tool, per Deezer's later FAQ update on the same pageCompany's own claim[1]

Takeaway

A streaming service treated AI-generated uploads as a content-quality and fraud problem and built its own filter. The accuracy figure is Deezer's own.
