So, first, there’s an issue where the model isn’t “remembering” having “seen” all of the text. It was updated by gradients taken over its outputs on the historical corpus. So there’s a subtlety, such that “which worlds are consistent with observations” is a wrongly-shaped claim. (I don’t think you fell prey to that mistake in OP, to be clear.)
Second, on my loose understanding of metaphysics (ie this is reasoning which could very easily be misguided), there exist computable universes which contain entities training this language model given this corpus / set of historical signals, such that this entire setup is specified by the initial state of the laws of physics. In that case, the corpus and its regularities (“dogs” and “syntax” and such) wouldn’t necessarily reflect the world the agent was embedded in, which could be anything, really. Like maybe there’s an alien species on a gas giant somewhere which is training on fictional sequences of tokens, some of which happen to look like “dog”.
Of course, by point (1), what matters isn’t the corpus itself (ie what sentences appear) but how that corpus imprints itself into the network via the gradients. And your post seems like evidence that even a relatively underspecified corpus (sequences of legal Othello moves) appears to imprint itself into the network, such that the network has a world model of the data generator (i.e. how the game works in real life).
Does this make sense? I have some sense of having incommunicated poorly here, but hopefully this is better than leaving your comment unanswered.
