I believe the resulting models would be the same. I don't know all the internals on how something like Dalle generates its images, but let's assume that if you then gave both models the same text prompt and random seed, they would generate the same images in the same order. Although I would argue that if this system was sentient, all we've done is clone/recreate the sentient system. The ability to clone/recreate an intelligence does not contradict that there was a sentience, I believe. The human equivalent would be if you could create two molecularly identical brains, and have them experience the exact same lives for some time, controlling all stochastic processes, would they be the same person? Obviously it's not possible to control these things in the physical world, but even if you did get the same person, that doesn't make either any less sentient.
