    > “Zero hallucination.”

    This is the part that bothers me the most. How is it 0 hallucination, if the correct answer is not even the part of the options. There is no way to mark absentia or a way to know I absolutely cannot choose any of the options.

    I am wondering, if anyones tried dead simple combinations of embedding with logistic regression to solve classifications problems?

      Can’t produce text ergo can’t hallucinate I think is the marketing claim

        Of course you can generate text. You just need to run it in an autoregressive loop as a sort of reverse of all the fun Jev-like papers that have come out in the last couple days. Ask it to predict the next letter in a string, then sample at your favorite temperature, then predict the next letter, etc. This will be quite expensive, and it may work terribly. I’m not personally inclined to try it. I am, however, curious whether it would work less horribly if you correctly guess what tokenizer the input uses and request a choice over next tokens consistent with the tokenizer in question.

        It would be absolutely hilarious if you did this, asked it which model it was, and it gave a recognizable answer that wasn’t Jev.
