Sure seems like Fenix Flexin used AI music generator Treblo
TL;DR
Treblo has released an open-source AI Music Classifier that detects whether a song was generated with its own tool, though not with other AI generators. The company reports a false positive rate below 1 in 10,000. Applied to Fenix Flexin's track Rubberz, the classifier rated it very likely Treblo with high confidence. The result adds weight to suspicions that the song was AI-generated.
Nauti's Take
An open-source classifier that flags a vendor's own output is real progress for music editors and labels, because provenance questions can finally be tested reproducibly. The limit is obvious: the tool only recognises Treblo material, and a false positive rate below 1 in 10,000 sounds strong while covering neither other generators nor heavily remastered tracks.
Teams using AI music commercially should treat such results as strong evidence and keep their own provenance records for every track.
