Fenix Flexin denies AI use — but Treblo's new tool detects it

treblo released an open-source 'ai music classifier' designed to detect content created specifically by its model, reporting a false positive rate of less than 1 in 1,000 analyses. the company used this tool to identify fenix flexin's controversial single 'rubberz' as ai-generated with 'high confidence,' directly contradicting fenix's public claims that the song was a human composition. treblo ceo ryan tremblay stated the probability suggests the song was generated almost entirely by their model, arguing it represents the first ai-generated track to chart on the billboard hot 100. this development highlights the growing necessity for provenance tools in the generative audio space, as artists and platforms face increasing difficulty distinguishing between synthetic and human-created content.
