From the abstract

Large Language Models (LLMs) have emerged as a groundbreaking technology with their unparalleled text generation capabilities across various applications. Nevertheless, concerns persist regarding the accuracy and appropriateness of their generated content. A contemporary methodology, self-correction, has been proposed as a remedy to these issues. Building upon this premise, this paper critically examines the role and efficacy of self-correction within LLMs, shedding light on its true potential and limitations. Central to our investigation is the notion of intrinsic self-correction, whereby an LLM attempts to correct its initial responses based solely on its inherent capabilities, without the crutch of external feedback. In the context of reasoning, our research indicates that LLMs struggle to self-correct their responses without external feedback, and at times, their performance even degrades after self-correction. Drawing from these insights, we offer suggestions for future research and practical applications in this field.

> The implications are vast. We may be able to translate between languages that have never had a “Rosetta Stone”. Any animals that have a true language could have it decoded. And while an LLM that’s gotten an 8 year old’s understanding of balancing assorted items isn’t that useful, an LLM that’s got a baby whale’s grasp on whale language would be revolutionary. Given that almost no-one trusts these LLMs for anything serious beyond creative / BS generating uses, this article does a lot of glossing over the reliability of their outputs and focuses more on such utopian promises with claims of 'understanding' which is in this article is beyond absurd and nonsensical.

reality of LLMs is that they cannot reason. [0] It is known that LLMs perform incredibly worse in mathematical reasoning and understanding which it consistently hallucinates the wrong answers [1] and even when you tell it to correct itself, it pretends to identify its mistake and regurgitates another incorrect answer and its answers get even worse further down the conversation. [2] Of course to the typical user, it's easy to be fooled by a stochastic parrot pretending to demonstrate reasoning. But experts understand that these systems cannot transparently explain themselves and are AI sophists which fundamentally cannot be trusted.

The paper: https://arxiv.org/pdf/2310.01798.pdf > Our research shows that LLMs are not yet capable of self-correcting their reasoning The paper actually just shows that the particular "self-correction" strategy and set of prompts they used doesn't help for the tasks they looked at, for the models they looked at. It may be the case in general, but it may not. > it is plausible that there exist specific prompts or strategies that could enhance the reasoning performance of models for particular benchmarks Seems they agree. So the wording of the title/conclusion is too strong. > searching such prompts or strategies may inadvertently rely on external feedback, either from…

human insights or training data I'm not sure this justifies picking a single prompting strategy, and not looking at the impact of different prompting strategies. Even just writing a few different prompts in advance with different wordings and showing the variation in results would have been helpful.
