I’ve noticed dsv4 do that as well, but inconsistently. I thought it was broken at first, but no, it’s just kind of shorthand that it does while thinking.
It’s also a little bit snarky, almost. The stuff it thought during the car wash puzzle made me laugh.
It wouldn't accept it was the Glimmer model and I had to stop when I realized I was arguing with my GPU. Was a surreal moment, lol.
