But you can still be creative if you keep every outcome, it would be very hard to prove creativity if you discard everything. The one could argue you're creative the moment you select something.
I don't think all creativity requires intentionality. Some forms of creativity are the accumulation of unintentional outcomes, like when someone sets out to copy a thing, but due to mistakes or other factors outside their control end up with something unique to what they were going for.
How that preclude these models from being creative? Randomness within rules can be pretty creative. All life on earth is the result of selection on random mutations. Its output is way more structured and coherent than random noise. That's not a good comparison at all.
Either way, generative tools are a great way for the people using to create with, no model has to be creative on its own.
It's a lot less than playing a video game. My fans on my GPU spin up harder and for more sustained time whenever I'm playing.
