Fenix Flexin appears to acknowledge AI was used in the song 'Rubberz' as scrutiny centers on Treblo
The Verge reports that rapper Fenix Flexin now appears to be acknowledging AI use in the creation of 'Rubberz,' an 80s synth pop-themed track that had drawn scrutiny from producer Medasin. The report ties the song to allegations that the AI music tool Treblo, formerly called Sonauto, was used, and notes that the company has released an AI detector that flags the track.
Why it matters: The episode adds to growing debate over disclosure, attribution, and verification in AI-generated music. A public artist acknowledgment combined with a vendor-built detection tool could shape how audiences, collaborators, and platforms assess whether commercially released songs were made with generative AI.
