Treblo Tool Flags Fenix Flexin Song as Likely AI-Generated

Treblo’s detector plus a co‑founder’s comment say the Hot 100 single "Rubberz" likely used its model, prompting urgent questions over disclosure of AI involvement by labels, platforms, chart bodies.

Overview

  • A viral technical takedown by producer Medasin showed a snippet filename referencing Sonauto (Treblo’s former name) and demonstrated how Treblo can reproduce the song’s vocal style, triggering renewed scrutiny of authorship.
  • Fenix Flexin has denied using AI and posted a Pro Tools project walkthrough meant to prove manual creation, but critics remained unconvinced and the video was later deleted.
  • Independent analyses, including a detailed breakdown in The Verge, identified audio artifacts — brittle hi‑hats, cut‑off reverb tails, and low‑bitrate sounding backing vocals — that experts say are commonly found in generative‑music output.
  • Treblo released a classifier that labeled the publicly available Rubberz file as “very likely Treblo,” and a co‑founder acknowledged someone used the model to find a popular sound, which together strengthen but do not absolutely prove the AI link.
  • The episode highlights gaps in forensic certainty and disclosure: it raises questions about chart eligibility, royalty reporting, and the need for clear provenance standards as AI tools make commercially successful tracks easier to produce.
