Are collabs a good way to see if an artist is AI or not?

(Dunno what the flairs mean so I guess this is the best one?)

So, I like discovering new music, and the way I do it is using recommendations on discord and taking spotify playlists and putting the songs I find intresting in my apple music. AI makes it a bit harder, since AI uses a style that has taken inspiration from other metal acts. While making one yesterday, I was investigating another artist who I have never heard of, and I saw they made a collab with a band I was already familiar with, which is why I was confident that it wasn’t AI. So, can I apply this rule in the future or do AI artists also collab with eachother? I try to stay as far away from AI music as possible but the only AI artists I see only do solo work
