Treblo detector flags Fenix Flexin's 'Rubberz' as AI-made

What happened

Treblo, an AI music generator, announced an open-source detection tool on Monday that identifies songs created with its model. The tool flagged Fenix Flexin's chart hit 'Rubberz' as 'very likely Treblo' with 'high confidence,' suggesting it was generated almost entirely by Treblo's model—which would make it the first known AI-generated song to reach the Billboard Hot 100.

Why it matters

Fenix Flexin has denied the song was AI-made and posted low-quality video clips claiming to show project files from the recording session, but those posts have failed to dispel allegations. If confirmed, the song's chart success would mark a watershed moment: a major hit explicitly built with AI generation tools, raising questions about disclosure and authenticity in music.

What to watch

Treblo CEO Ryan Tremblay said the classifier has a false positive rate of less than 1 in 10,000. The tool detects songs made with Treblo specifically, not other AI music generators, so it cannot confirm whether other parts of the production used different AI tools or non-AI methods.
