Fenix Flexin Confirms AI Role in Billboard-Charting Hit “Rubberz”

Fenix Flexin, a member of Shoreline Mafia, has publicly acknowledged that the AI software Treblo was used in the creation of his viral synth-pop single “Rubberz.” The admission follows months of avoidance and partial denials by the rapper and his producer Purps On The Beat.

The track, released in June, immediately drew attention for its “80s-style, British-accented” vocals, prompting listeners and analysts to suspect generative-AI involvement. Producer Medasin’s viral breakdown and Treblo’s own detection tool later flagged the song as “very likely” generated with its model, a tool that claims a false-positive rate below 1 in 10,000. Prior to the admission, Fenix Flexin responded to AI accusations in interviews by deflecting, saying he could “record a whole record” in a British accent without AI assistance. Both he and Purps On The Beat had previously denied the claims in social-media comments and a Channel 5 interview with Andrew Callaghan.

According to Complex, “Rubberz” became the first fully AI-generated track to enter the Billboard Hot 100, peaking at No. 58. The chart placement underscores the commercial impact of a song whose production involved AI-assisted elements, even though the artist maintains that the technology did not affect the recording stage.

• Fenix Flexin (artist) – In the Instagram comment cited above, he framed AI as a neutral tool, emphasizing that it “didn’t affect the recording process.”

Complex

• Treblo (AI software company) – Confirmed through its vetting software that its model was used to create “Rubberz,” reinforcing the technical basis for the AI claim.

• Complex (reporting outlet) – Reported the false-positive rate of Treblo’s detection tool as below 1 in 10,000, lending credibility to the AI identification.

Later, Treblo’s detection and Medasin’s analysis suggested AI use, creating a discrepancy between the artists’ public denials and third-party technical findings. The artist’s eventual admission acknowledges AI’s role but continues to claim the recording process remained untouched, a point not independently verified by the sources.

The episode illustrates a growing tension in the music industry between emerging generative-AI tools and traditional notions of artistic creation. As more artists experiment with AI-assisted composition, the “Rubberz” case may set a precedent for how chart-eligible songs are credited and how audiences perceive authenticity. The admission also aligns with a broader trend of artists—such as Tyga, who recently admitted AI use on his album *$tarface*—being more forthcoming about integrating new technology into their work.

No specific future events or scheduled actions were detailed in the sources. The discussion around AI’s role in mainstream music production is expected to continue as additional tracks employing similar tools emerge.
