  • let’s see if we can find supporting information on this answer elsewhere or, maybe ask the same question a different way to see if the new answer(s) seem to line up

    Yeah, that’s probably the best way to go about it, but still requires some foundational knowledge on your part. For example, in a recent study I worked on we found that programming students struggle hard when the LLM output is wrong and they don’t know enough to understand why. They then tend to trust the LLM anyways and end up prompting variations of the same thing over and over again to no avail. Other studies similarly found that while good students can work faster with AI, many others are actually worse off due to being misled.

    I still see them largely as black boxes

    The crazy part is that they are, even for the researchers that came up with them. Sure we can understand how the data flows from input to output, but realistically not a single person in the world could look at all of the weights in an LLM and tell you what it has learned. Basically everything we know about their capabilities on tasks is based on just trying it out and seeing how well it works. Hell, even “prompt engineers” are making a lot of their decisions based on vibes only.


  • I don’t know if it’s just my age/experience or some kind of innate “horse sense” But I tend to do alright with detecting shit responses, whether they be human trolls or an LLM that is lying through its virtual teeth

    I’m not sure how you would do that if you are asking about something you don’t have expertise in yet, as it takes the exact same authoritative tone no matter whether the information is real.

    Perhaps with a reasonable prompt an LLM can be more honest about when it’s hallucinating?

    So far, research suggests this is not possible (unsurprisingly, given the nature of LLMs). Introspective outputs, such as certainty or justifications for decisions, do not map closely to the LLM’s actual internal state.








  • I have a compsci background and I’ve been following language models since the days of the original GPT and BERT. Still, the weird and distinct behavior of LLMs hasn’t really clicked for me until recently when I really thought about what “model” meant, as you described. It’s simulating what a conversation with another person might look like structurally, and it can do so with impressive detail. But there is no depth to it, so logic and fact-checking are completely foreign concepts in this realm.

    When looking at it this way, it also suddenly becomes very clear why people frustratedly telling LLMs things such as “that didn’t work, fix it” is so unproductive and meaningless: what would follow that kind of prompt in a human-to-human conversation? Structurally, an answer that looks very similar! Therefore the LLM will once more produce a structurally similar answer, but there is literally no reason why it would be any more “correct” than the prior output.
