Fenix Flexin isn’t even denying using AI to make ‘Rubberz’ anymore

LA rapper Fenix Flexin basically admitted he used AI to help make his song 'Rubberz.' He'd been dodging the question until now, and an AI detector called him out.

For weeks, Fenix Flexin dodged the obvious question hanging over his 80s synth-pop throwback "Rubberz": did a machine write part of this thing? He's stopped dodging. In a comment reply on Instagram, the LA rapper finally cracked open the door, writing that he "never said I didn't use AI," only that it "had nun to do w recording process," and that he didn't even know the name of the app until the song was already being mixed.
That's a pretty specific kind of admission — not a confession, exactly, but not a denial either. It arrived after producer Medasin posted videos alleging that Fenix used Treblo, an AI music tool that used to go by the name Sonauto, to help construct "Rubberz." Treblo didn't just sit back and let the accusation float. The company rolled out its own AI detector and ran the track through it, and the tool flagged the song as Treblo-made. Even the cover art, honestly, looks like it came out of a diffusion model rather than a designer's hand.
The timing here matters. Fenix's half-admission landed on a post about Tyga, who copped to using AI on his own polarizing 80s-inspired album $tarface months back. Someone pointed out the parallel in the comments, and that's what pulled the response out of Fenix. Two rappers, two AI-assisted throwback records, two very different levels of upfront honesty — until now.
What's interesting isn't that AI showed up in a rap song's production chain. That ship sailed a while ago. It's the specific hedge Fenix reached for: AI touched the song, sure, but not the recording process, and he claims ignorance about which tool it even was. That's a defense built for a moment when using AI isn't shameful exactly, but claiming full authorship still is. Musicians are learning to thread that needle in real time, and the phrasing they choose says a lot about where the industry's comfort line currently sits.
My take — AI-written commentary, not fact-checked reporting
Nobody's outraged that a rap song used an AI tool — they're annoyed it took a detector company publicly outing the track before anyone copped to it. If artists want credit for embracing new tools, they should say so before getting caught, not after a company builds a product specifically to catch them.
