Rapper Fenix Flexin Now Says He Never Denied Using AI on 'Rubberz', But He Did
After months of insisting his retro synth-pop track was fully human-made, the LA rapper has quietly shifted his story. The receipts tell a different tale.
Key points
- LA rapper Fenix Flexin stated in a Hot 97 interview in July 2026 that there was "no AI on" his song "Rubberz."
- In August 2026, Fenix posted an Instagram comment claiming he "never said" he did not use AI on the track.
- Producer Medasin publicly claimed an AI music tool called Treblo (formerly Sonauto) was used to create the song.
- Treblo released its own AI detection tool, which flagged "Rubberz" as AI-generated.
- Rapper Tyga also faced similar controversy in 2026 over his 80s-influenced album $tarface, which he admitted involved AI.
LA rapper Fenix Flexin has changed his story on whether artificial intelligence helped make his hit song "Rubberz," an 80s synth-pop track that went viral this year. The shift is hard to square with what he said on record just weeks ago.
In a reply posted to one of his Instagram posts, 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 it and erbody started commenting. ain't nothing wrong w using new technology as a tool keep up w the times or get left behind."
What did he actually say before?
He said, plainly, that there was no AI on the song. On Hot 97's Mornings With Mero, interviewer Kazeem Famuyide asked him directly about AI use. Fenix replied: "no AI on it."
That was not a one-off. Over several weeks, Fenix and his team posted what they described as recording session files showing two humans at work. They commented on fan posts to insist the song was made "with pro tools auto tune and some reverb" in his living room. When videos circulated that appeared to show him lip-syncing, his camp said he was genuinely singing.
Now he says he never denied it.
What started the allegations?
Producer Medasin posted videos claiming that a tool called Treblo, an AI music generation platform previously named Sonauto, had been used to create "Rubberz." Treblo then released an AI detection tool. It flagged the song as AI-generated content from its own platform.
Fenix is not alone in this. Rapper Tyga faced nearly identical scrutiny in 2026 over $tarface, his own 80s-flavoured album. Tyga eventually admitted he had used AI tools to make it, first reported by The Verge.
What does this mean for music fans?
For listeners, the practical question is straightforward: when an artist or their label says a song is human-made, that claim may not hold. AI music generation tools can now produce tracks that sound like vintage studio recordings, and the gap between a synthesiser played by hand and one simulated by software is no longer obvious to the ear.
There is no law requiring artists to disclose AI use in songwriting or production in the United States as of mid-2026, though several industry bodies are pushing for labelling standards. Until those exist, listeners have limited ways to verify what they are hearing.
Fenix's Instagram comment frames AI as just another tool, the same way an artist might use auto-tune or reverb. That argument has genuine merit in many contexts. What it does not resolve is why, for several weeks, he said the opposite.
