Fenix Flexin has admitted using artificial intelligence to generate the vocals for his track “Rubberz”, a song themed around 1980s synth pop. The Los Angeles rapper confirmed the tool was Treblo, formerly known as Sonauto, after producers released an AI detector that flagged the audio. Flexin clarified on Instagram that he never denied using the technology, noting he only stated it had nothing to do with the recording process. He explained he did not know about the specific application until the mixing stage was complete.
This admission marks a shift from previous denials regarding the use of generative tools in mainstream hip hop. The case highlights how quickly artificial intelligence can become embedded in commercial music production without initial transparency. It also raises questions about how listeners identify synthetic voices within a genre that frequently mimics past decades.
* The artist previously claimed the AI was unrelated to recording
* Treblo released a specific detector to identify the generated audio
* The track is the latest example of synthetic vocals on a Billboard Hot 100 chart
