Are they? I thought there was always a kind of “random parameter” or random step midway?

Hope this question is not too dumb!

Usually not, perhaps noise filters, but mostly not. There was amusing case of reversing twirl filter a while ago: https://boingboing.net/2007/10/08/untwirling-photo-of.html

Surely that twirl effect isn't made using AI but just a geometric function, right?

[pfortuny]

Thanks a lot. I was mistaken.

It depends on the algorithm, but many models can be re-generated if you start with the same seed.

[msk-lywenn]

Is it common and/or expected to have control over the seed though?

[comboy]

Yes, if you are fine tuning some other parameters you need to keep the seed the same to be able to have any idea what you're doing.

Thank you! I was mistaken then.
