It took a few weeks, some very public accusations, and enough online drama to fill a group chat — but LA rapper Fenix Flexin has finally admitted what many already suspected: his viral hit "Rubberz" was made using AI. And apparently, he thinks that's totally fine.

From Denying to Defending

When producer Medasin first called out Fenix Flexin earlier this month, claiming an AI tool called Treblo (formerly Sonauto) was used to create "Rubberz," the rapper was quick to push back. On Hot 97's Mornings With Mero, he insisted there was "no AI on it." He and his team posted clips they claimed were from real recording sessions, complete with what looked like pro tools and reverb, and even accused people of lip-syncing during what they said were actual live takes.

But as more evidence piled up — including Treblo's own AI detector confirming the track came from their platform — Fenix apparently decided to change his story. In an Instagram comment responding to someone comparing the situation to Tyga's own AI controversy, Fenix finally said what critics had been waiting for:

"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."

So, to be clear: he did deny it. Multiple times. On TV, on social media, in comment sections. But now he's saying he never actually said that. Cool, cool.

What Is Treblo (Formerly Sonauto)?

For those catching up, Treblo is an AI music generation tool that can create full songs — from instrumentals to vocals — based on text prompts. Think of it as ChatGPT, but for music. The tool formerly went by Sonauto before rebranding. According to reports, Treblo even released an AI detector specifically designed to identify tracks made with their platform, and wouldn't you know it — "Rubberz" came back flagged as a 97% match for Treblo-generated audio.

Why This Is a Big Deal

"Rubberz" isn't some random SoundCloud loosie — it reportedly charted on the Billboard Hot 100. That means an AI-generated track, one that the artist publicly denied using AI to create, made it onto one of the most prestigious music charts in the world.

This raises some big questions the music industry is still trying to answer:

• Do listeners have a right to know if a song was made by AI? If you stream something thinking a human poured their heart into it, and it turns out an algorithm wrote the whole thing, does that matter?
• How should chart rankings handle AI music? Billboard doesn't currently require disclosure of AI involvement — but after this story, that policy might need a second look.
• What does this mean for human producers and artists? If a guy can feed a prompt to an app and land on Billboard, what's the point of spending years learning to produce?

Fenix Isn't Apologizing

In case you were hoping for some accountability, Fenix's comment section response makes his position pretty clear: he's not sorry. He frames using AI as simply "keeping up with the times." And honestly? He's probably not wrong that AI tools are becoming a legitimate part of music production. The issue isn't necessarily that he used the tool — it's that he lied about it, got caught, and then tried to rewrite history.

Meanwhile, Tyga recently faced similar backlash after admitting he relied on AI for his own '80s-influenced album $tarface. It seems like every week, another artist is getting caught in the AI music controversy. As these tools get better and cheaper, this is only going to keep happening.

So What Now?

The music world is at a crossroads. AI can make music faster and cheaper than any human studio session. Artists can go from prompt to Billboard hit in days. But when the line between human creativity and AI generation gets this blurry, audiences deserve honesty about what they're actually listening to.

Whether Fenix Flexin learned anything from this mess is unclear. But one thing's for sure — "Rubberz" won't be the last AI hit to spark this kind of controversy. The question is whether the industry will get ahead of it, or keep playing catch-up every time another artist gets exposed.
