Sure seems like Fenix Flexin used AI music generator Treblo

A new AI detection tool developed by Treblo has identified the song 'Rubberz' by Fenix Flexin as being highly likely generated by their AI model. Despite the company's claims and the tool's high confidence score, the artist continues to deny the use of AI in his music production.
Why it matters
This incident highlights the growing tension between AI-generated content and artistic authenticity, as well as the emergence of proprietary detection tools in the music industry.
We were pretty sure that Fenix Flexin’s “Rubberz” was made using AI, but musician Medasin was confident that it was made using Treblo specifically. Now the company and a new detection tool seem to confirm it.
On Monday, the company announced the open-source Treblo AI Music Classifier, which detects when a song was generated using Treblo, though not other AI tools. According to a blog post, it has a false positive rate of less than 1 in 1,000. That’s not unimpeachable, but it’s notable that the company’s own Classifier determined that “Rubberz” was “very likely Treblo” with “high confidence,” adding more fuel to the PR nightmare for Fenix.
