AI agents wrong ~70% of time: Carnegie Mellon study

Technology

  • I'm in a workplace that has tried not to be overbearing about AI, but has encouraged us to use them for coding.

    I've tried to give mine some very simple tasks like writing a unit test just for the constructor of a class to verify current behavior, and it generates output that's both wrong and doesn't verify anything.

    I'm aware it sometimes gets better with more intricate, specific instructions, and that I can offer it further corrections, but at that point it's not even saving time. I would do this with a human in the hopes that they would continue to retain the knowledge, but I don't even have hopes for AI to apply those lessons in new contexts. In a way, it's been a sigh of relief to realize just like Dotcom, just like 3D TVs, just like home smart assistants, it is a bubble.

    The first half dozen times I tried AI for code, across the past year or so, it failed pretty much as you describe.

    Finally, I hit on some things it can do. For me: keeping the instructions more general, not specifying certain libraries for instance, was the key to getting something that actually does something. Also, if it doesn't show you the whole program, get it to show you the whole thing, and make it fix its own mistakes so you can build on working code with later requests.

  • No, it matters. Youre pushing the lie they want pushed.

    And you're pushing a hate train with no aspect of nuance to show for it.

    Seems like you are even less than 30% useful. And that is mainly because you can be used as fertilizer.

  • and doesn't need to be exactly right

    What kind of tasks do you consider that don't need to be exactly right?

    Description generators for TTRPGs, as you will read through them afterwards anyway and correct when necessary.

    Generating lists of ideas. For creative writing, getting a bunch of ideas you can pick and choose from that fit the narrative you want.

    A search engine like Perplexity.ai which after searching summarizes the web page and adds a link to the page next to it. If the summary seems promising, you go to the real page to verify the actual information.

    Simple code like HTML pages and boilerplate code that you will still review afterwards anyway.

  • When LLMs get it right it's because they're summarizing a stack overflow or GitHub snippet it was trained on. But you loose all the benefits of other humans commenting on the context, pitfalls and other alternatives.

    You mean things you had to do anyway even if you didn't use LLMs?

  • That’s literally how “AI agents” are being marketed. “Tell it to do a thing and it will do it for you.”

    So? That doesn't mean they are supposed to be used like that.

    Show me any marketing that isn't full of lies.

    Have you tried insulting the AI in the system prompt (as well as other tunes to the system prompt)?

    I'm not joking, it really works

    For example:

    Instead of "You are an intelligent coding assistant..."

    "You are an absolute fucking idiot who can barely code..."

  • Emotion > Facts. Most people have been trained to blindly accept things and cheer on what fits with their agenda. Like technbro's exaggerating LLMs, or people like you misrepresenting LLMs as mere statistical word generators without intelligence. That's like saying a computer is just wires and switches, or missing the forest for the trees. Both is equally false.

    Yet if it fits with the emotional needs or with dogma, then other will agree. It's a convenient and comforting "A vs B" worldview we've been trained to accept. And so the satisfying notion and misinformation keeps spreading.

    LLMs tell us more about human intelligence and the human slop we've been generating. It tells us that most people are not that much more than statistical word generators.

    people like you misrepresenting LLMs as mere statistical word generators without intelligence.

    You've bought-in to the hype. I won't try to argue with you because you aren't cognizent of reality.

    You’re not wrong, but often I’m just trying to do something I’ve done a thousand times before and I already know the pitfalls. Also, I’m sure I’ve copied code from stackoverflow before.

    “You are an absolute fucking idiot who can barely code…”

    Honestly, that's what you have to do. It's the only way I can get through using Claude.ai. I treat it like it's an absolute moron, I insult it, I "yell" at it, I threaten it and guess what? the solutions have gotten better. not great but a hell of a lot better than what they used to be. It really works. it forces it to really think through the problem, research solutions, cite sources, etc. I have even told it i'll cancel my subscription to it if it gets it wrong.

    no more "do this and this and then this but do this first and then do this" after calling it a "fucking moron" and what have you it will provide an answer and just say "done."

    This is the same kind of short-sighted dismissal I see a lot in the religion vs science argument. When they hinge their pro-religion stance on the things science can’t explain, they’re defending an ever diminishing territory as science grows to explain more things. It’s a stupid strategy with an expiration date on your position.

    All of the anti-AI positions, that hinge on the low quality or reliability of the output, are defending an increasingly diminished stance as the AI’s are further refined. And I simply don’t believe that the majority of the people making this argument actually care about the quality of the output. Even when it gets to the point of producing better output than humans across the board, these folks are still going to oppose it regardless. Why not just openly oppose it in general, instead of pinning your position to an argument that grows increasingly irrelevant by the day?

    DeepSeek exposed the same issue with the anti-AI people dedicated to the environmental argument. We were shown proof that there’s significant progress in the development of efficient models, and it still didn’t change any of their minds. Because most of them don’t actually care about the environmental impacts. It’s just an anti-AI talking point that resonated with them.

    The more baseless these anti-AI stances get, the more it seems to me that it’s a lot of people afraid of change and afraid of the fundamental economic shifts this will require, but they’re embarrassed or unable to articulate that stance. And it doesn’t help that the luddites haven’t been able to predict a single development. Just constantly flailing to craft a new argument to criticize the current models and tech. People are learning not to take these folks seriously.

    I frequently find myself prompting it: "now show me the whole program with all the errors corrected." Sometimes I have to ask that two or three times, different ways, before it coughs up the next iteration ready to copy-paste-test. Most times when it gives errors I'll just write "address: " and copy-paste the error message in - frequently the text of the AI response will apologize, less frequently it will actually fix the error.

    He's developing a toxic relationship with his AI agent. I don't think it's the best way to get what you want (demonstrating how to be abusive to the AI), but maybe it's the only method he is capable of getting results with.

    Maybe the marketers should be a bit more picky about what they slap "AI" on and maybe decision makers should be a little less eager to follow whatever Better Auto complete spits out, but maybe that's just me and we really should be pretending that all these algorithms really have made humans obsolete and generating convincing language is better than correspondence with reality.

    I’m not sure the anti-AI marketing stance is any more solid of a position. Though it’s probably easier to defend, since it’s so vague and not based on anything measurable.

    Calling AI measurable is somewhat unfounded. Between not having a coherent, agreed-upon definition of what does and does not constitute an AI (we are, after all, discussing LLMs as though they were AGI), and the difficulty that exists in discussing the qualifications of human intelligence, saying that a given metric covers how well a thing is an AI isn't really founded on anything but preference. We could, for example, say that mathematical ability is indicative of intelligence, but claiming FLOPS is a proxy for intelligence falls rather flat. We can measure things about the various algorithms, but that's an awful long ways off from talking about AI itself (unless we've bought into the marketing hype).

    So you’re saying the article’s measurements about AI agents being wrong 70% of the time is made up? Or is AI performance only measurable when the results help anti-AI narratives?

    In April, Nigeria asked Google, Microsoft, and Amazon to set concrete deadlines for opening data centers in the country. Nigeria has been making this demand for about four years, but the companies have so far failed to fulfill their promises. Now, Nigeria has set up a working group with the companies to ensure that data is stored within its shores. Just onshoring the data center does not solve the problems. You can't be sure no data travels to the US servers, some data does need to travel to the US servers, and the entire DC is still subject to US software and certificate keychains. It's better, but not good or safe. I need to channel my inner Mike Ehrmantrout to the US tech companies and government: you had a good thing going you stupid son of a bitch. You had everything you needed and it all ran like clockwork. You could have shut your mouth, cooked, and made as much money as you needed, but you just had to blow it up, you and your pride and your ego. Seriously, this is a massive own goal by the US government. This is a massive loss to US hegemony and influence around the world that's never coming back. It has never been easier to build sovereign clouds with off the shelf and open source tooling. The best practices are largely documented, software is commoditized, and there are plenty of qualified people out there these days and governments staring down the barrel of existential risk have finally got the incentive to fund these efforts.

    Just saw this article linked in a ThePrimeagen video. I didn't watch the video, but I did read the article, and all of this article is exactly what I'm always saying when I'm complaining about current UI trends and why I'm so picky about the software I use and also the tools I use to write software. I shouldn't have to be picky, but it seems like developers (professional and hobbyist alike) don't care anymore and users don't have standards.

    CBDCs could well take the prize for most dangerous thing in our lifetime, similar to nuclear weapons during the Cold War. I'm thinking of that line from the song in Les Mis. Look down, look down. You'll always be a slave. Look down, look down. You're standing in your grave.
