…Ensembling and self-criticism are not necessarily related. The way you decide the final output from the ensemble is you usually just take the majority response and you're done. So self-criticism is going to be a bit different in that you have one prompt, one initial output from that prompt, and then you tell the model, okay, look at this question and this answer. Do you agree with this? Do you have any criticism of this? And then you get the criticism and you tell it to reform its answer appropriately. And that's pretty much what self-criticism is. I actually do want to go back to what you said though, because it made me remember another prompting technique, which is ensembling, and I think it's an ensemble. I'm not sure where we have it classified. But the idea of this technique is you sample multiple chain-of-thought reasoning paths, and then instead of taking the majority as the final response, you put all of the reasoning paths into a prompt, and you tell the model, examine all of these reasoning paths and give me the final answer. And so the model could sort of just say, okay, I'm just going to take the majority, or it could see something a bit more interesting in those chain-of-thought outputs and be able to give some result that is better than just taking the majority. Yeah, I actually do this for my summaries. I have an ensemble and then I have another LM go on top of it. I think one problem for me for designing these things with cost awareness is the question of, well, okay, at the baseline, you can just use the same model for everything, but realistically you have a range of models, and actually you just want to sample all range. And then there's a question of, do you want the smart model to do the top level thing, or do you want the smart model to do the bottom level thing, and then have the dumb model be a judge? If you care about cost. I don't know if you've spent time thinking on this, but you're talking about a lot of tokens here, so the cost starts to matter. I definitely care about cost. I think it's funny because I feel like we're constantly seeing the prices drop on intelligence. Yeah, so maybe you don't care.…
