The prompts or at least being fed a sequence of tokens including output from prior passes is integral to how language models function. Rather than being “hooked up to one” the neural networks only function is to pick a single token based on a set of inputs. So without being feed it’s own output you get a single token and then nothing. There’s some randomness injected into the process and whatnot but that’s ultimately…
No, it doesn't pick a single token based on a set of inputs. It predicts a probability distribution for the next token given the previous tokens. That's why techniques like beam search and Viterbi work so well - you don't have to commit to the next token at each step. And temperature (what I assume you mean by "randomness injected") isn't "window dressing," it fundamentally gives better results because LMs model prob…
As to randomness that’s simply one approach, there’s deterministic approaches that have their own advantages. What randomness provides over them is avoiding always responding to the same opening in the same way as that’s quite off-putting.
