The key points
- 1.Fenix Flexin appeared to acknowledge AI use on "Rubberz."
- 2.Treblo’s classifier flagged the song as very likely Treblo-made.
- 3.The detector is limited to Treblo-generated music.
LA rapper Fenix Flexin appeared to acknowledge using AI for his 80s synth pop-themed song "Rubberz," saying in an Instagram reply that he "never said" he did not use AI and that it was not part of the recording process. The comments followed producer Medasin’s claims that Treblo, formerly Sonauto, was used to make the song, and Treblo’s release of an open-source classifier that identified "Rubberz" as "very likely Treblo" with "high confidence." The company says its detector identifies Treblo-generated music, not output from other AI tools, and has a false positive rate of less than 1 in 1,000.
