Fenix Flexin has changed the public line around Fenix Flexin Rubberz AI claims. In an Instagram reply reported by The Verge, the Los Angeles rapper said he had not denied using artificial intelligence on “Rubberz,” while drawing a boundary around its role: he said it had nothing to do with the recording process.
That is a narrower account than his earlier one. During a Hot 97 appearance last month, Fenix said there was “no AI on it” when asked directly about the track, according to The Verge. He and people around the release had also previously attributed the sound to human recording, Pro Tools, Auto-Tune and reverb.
His latest comment does not establish how AI was used, when it entered the production, or whether it supplied any audio heard on the finished song. It does confirm that his position is no longer a blanket denial.
What did Fenix Flexin say about AI in “Rubberz”?
In the Instagram response, Fenix said he had “never said” he did not use AI, and said AI was unrelated to recording. He also said he did not know what the app was until the track was mixed, according to The Verge. He characterized AI as a tool and argued that artists should keep up with new technology.
The distinction matters because “recording process” is not a complete production history. A song can involve writing, composition, arrangement, generated demos, vocal processing, mixing and mastering. Fenix has not publicly specified where AI fit, if at all, among those stages.
Why was “Rubberz” linked to Treblo?
Questions over the June release escalated after producer Medasin argued that the track was connected to Treblo, a generative-music service previously called Sonauto. Wired and Pitchfork reported that Medasin pointed to an older Fenix video in which a filename appeared to end in “Sonauto.mp3.” Sonauto had changed its name to Treblo two days before “Rubberz” was released.
Medasin also made tracks with Treblo that he said resembled “Rubberz” in style and lyrical patterns. That is an allegation and demonstration, not an independent reconstruction of the song’s production session. Fenix sent Medasin clips that appeared to show separated song stems, Pitchfork reported, while commenters noted that software can split a finished recording into stems automatically.
Treblo later released a “Was This Made With Treblo?” detector that rated “Rubberz” as “very likely Treblo,” according to Pitchfork. The company’s cofounder, Ryan Tremblay, told Wired that someone appeared to have used its model. Neither statement independently verifies the track’s full creation process. Pitchfork reported that the classifier was open source but had not been independently reviewed.
For now, the confirmed change is modest but clear: Fenix acknowledges some AI use while maintaining that it was separate from recording. The specifics of that use remain unstated.
