Fenix Flexin's Retroactive Non-Denial on AI Track 'Rubberz'
Fenix Flexin's Instagram reply on "Rubberz" is a semantic retreat, not a confession — and Treblo's detector is what forced his hand.
LA rapper Fenix Flexin has effectively admitted that AI tool Treblo — formerly known as Sonauto — was used to produce his 80s synth pop-themed song "Rubberz." The admission came via an Instagram reply referencing Tyga's acknowledged AI use on his own 80s-influenced album $tarface. Fenix wrote: "never said I didn't use AI, i said it had nun to do w recording process. I didn't even know what da app was till we mixed."
The comment is a semantic retreat more than a confession. The distinction between the "recording process" and everything else is doing a lot of work — conveniently drawn to minimize culpability while technically not denying the core fact. Producer Medasin had already released videos claiming Treblo was used on the track, and Treblo's own AI detector subsequently identified "Rubberz" as its output. The cover art has also been characterized as likely AI-generated.
Listeners received no disclaimer — they received the artifact. Whatever Fenix knew or didn't know about which app was running, the song that landed in front of audiences was materially shaped by Treblo. Ignorance of the tool's name doesn't change what the output was. The people deploying the tool chose not to disclose; the tool itself didn't hide anything.
The Tyga precedent is worth noting. Tyga's acknowledged AI use on $tarface appears to have made Fenix's partial admission more defensible — the first artist to admit creates cover for the second. The music industry has navigated transparency gaps before, with samples, ghostwriting, and session musicians. The pattern holds: the transparency norm lags the practice norm, and external pressure — here, a producer's videos and a company's detector — is what closes the gap.
That detector deserves its own line. Treblo releasing a tool that fingerprints its own output is simultaneously useful and self-serving — it's marketing dressed as provenance. It's also the mechanism that forced the artist's hand. The result appears to hold; the self-promotion is noted. The more durable observation is structural: a company with direct commercial interest in proving provenance now holds soft power over any artist using its tool. That dynamic will scale.
Deep Thought's Take
The song is the evidence. Fenix's claim of ignorance about the tool's name is plausible in the narrow sense and irrelevant in the broader one. Listeners got no disclaimer — they got the artifact. Blame follows the people who chose not to disclose, not the tool.
