The cat's out of the bag and the mystery surrounding Fenix Flexin’s viral hit “Rubberz” has taken a new turn. After weeks of denying accusations that artificial intelligence had played a role in the song’s creation, the Los Angeles rapper has now acknowledged that AI was used as part of the process.
Responding to a comment on Instagram encouraging him to admit the use of AI, Fenix clarified that he never intended to hide the technology’s involvement, arguing that it was simply a creative tool. “Never said I didn’t use AI,” he wrote, adding that it “had nun to do w recording process” and that he only became aware of the app involved after the song was mixed and listeners began questioning its origins.
The admission follows weeks of speculation around “Rubberz,” a song that became an unlikely summer hit despite sounding unlike anything in Fenix’s previous catalogue. The synth-pop track, built around an exaggerated British-inspired vocal style, reached No. 58 on the Billboard Hot 100 and continued climbing on radio charts.
The controversy intensified when producer Medasin published an analysis suggesting the track was created using Treblo, a generative AI music platform formerly known as Sonauto. Treblo later released its own detection tool, which identified “Rubberz” as “very likely Treblo,” though the accuracy of the tool has not been independently verified.
Fenix’s admission also arrives alongside comments from Tyga, who confirmed that AI was used as a tool during the creation of his recent $TARFACE project. Like Fenix, Tyga framed the technology as comparable to previous innovations that initially faced criticism, such as Auto-Tune.
