I wonder how many choices you can give this thing in multiple choice response mode. I'm guessing you could give it enough choices to produce Turing complete programs one symbol at a time when running in a loop, or to hold a conversation when given a vocabulary as the choices. It would be particularly hilarious to just let it choose the next ASCII character of output in a loop.

My guess is that due to its design there is no support for prompt caching, as there would normally be no reason for it. So the performance of my idea would probably be appalling as every step in the loop would reevaluate every input and output token. But it would be interesting to see the outcome.
