Hm that's interesting. It seems like the most useful info is probably under the 'Landscape' tab.

Everything we came across building our own detector: the models and apps that spot AI music, the datasets they learn from, and the generators they are built to catch. Labelled open source, closed model, or commercial so you know what you can actually run.

I didn't really evaluate any of it though, so take that with a grain of salt.
