Treblo AI detector flags hit rap songs as synthetic

The generative music application Treblo has released an open-source detection tool called "Was This Made With Treblo?" that flags whether songs were created using its platform. Upon its release, the detector flagged "Rubberz," a synth-pop track by rapper Fenix Flexin that reached No. 58 on the Billboard Hot 100 and amassed 7 million views on its music video, as "Very likely Treblo." It also flagged a July track from rapper Tyga's "STARFACE" project as "Likely Treblo." This development follows accusations by independent producer Medasin, who noticed a "Sonauto.mp3" file suffix—referencing Treblo's former name, Sonauto—in one of Fenix's social media posts.

Medasin demonstrated how Treblo's engine frequently generates specific lyrical structures, such as "finger/linger" rhyme pairs, when prompted with "80s synthwave" and "rap lyrics." Treblo cofounder Ryan Tremblay confirmed the platform was unaware of the song's existence until it charted, but noted the tool's new detector has a false positive rate of under one in 10,000. To ensure transparency, the company has released the detector's underlying code under an open-source license for public inspection.

For AI practitioners and music industry professionals, this situation marks a critical shift in how synthetic media is monitored and monetized. As platforms like Tidal block monetization for AI-generated music and others introduce detection features, the ability to reliably audit audio files becomes essential. The release of open-source, highly specific detectors like Treblo's provides developers and distributors with the tools needed to enforce licensing agreements and maintain content integrity. It proves that proprietary model signatures can be identified with high statistical confidence, forcing a transition toward greater transparency in creative workflows.
