In its v6 announcement Suno names three label partners; it does not name the training catalogue

What the announcement establishes

Suno published v6 on 9 September in three variants: v6 and v6-wild for Pro and Premier subscribers, and v6-mini for everyone. The company describes the models as developed with its industry partners Warner Music Group, BMG and Believe. That sentence establishes a commercial relationship with three rights holders. It does not, on its own, establish which sound recordings went into training.^[1]

The distinction matters because the two statements sit at different points in the chain. A partnership names who agreed; a training list names what was used. The announcement carries the first and leaves the second out, so a listener who wants to know whose work shaped an output has nothing in this document to consult.^[1]

The opt-in that has not started

The announcement also describes opt-in experiences built around individual artists, where an artist chooses to take part and is paid when they do. As written, that is a design intention; the post carries no detail showing a mechanism already in operation, no start date, no payment formula and no way to see which artists have joined. Payment and attribution answer different questions, and only the first of them is named here.^[1]

This column found on 5 August that compensation can answer a licensing loss while the attribution question can stay open. Suno's v6 announcement falls on the same side of that divide: the label agreements settle who is paid, and the document says nothing about how an output would be traced back to a catalogue.^{[1], [2]}

What retiring the old models removes

Suno says that as v6 rolls out it will retire its previous models and move the service entirely onto the v6 generation. That closes a comparison. While both generations run, a listener or a researcher could put the same prompt to an old model and to v6 and hear whether the licensed material changed the output. Once the earlier models are gone, the only account of the change is the announcement itself.^[1]

What would close the gap is narrow and nameable: a training statement listing the catalogues v6 was built on, and an attribution method that matches a finished track to them. If either appears beside the artist opt-in Suno describes, the licensing claim becomes checkable; until then it rests on the partners' word. The feature list — section editing, mashups, sampling, audio isolation, lyric changes — describes what the model does, and none of it touches where the material came from.^[1]
