Yep. To add on, this is exactly what all the "AI haters" (myself included) are going on about when they say stuff like there isn't any logic or understanding behind LLMs, or when they say they are stochastic parrots.
LLMs are incredibly good at generating text that works grammatically and reads like it was put together by someone knowledgable and confident, but they have no concept of "truth" or reality. They just have a ton of absurdly complicated technical data about how words/phrases/sentences are related to each other on a structural basis. It's all just really complicated math about how text is put together. It's absolutely amazing, but it is also literally and technologically impossible for that to spontaneously coelesce into reason/logic/sentience.
Turns out that if you get enough of that data together, it makes a very convincing appearance of logic and reason. But it's only an appearance.
You can't duct tape enough speak and spells together to rival the mass of the Sun and have it somehow just become something that outputs a believable human voice.
For an incredibly long time, ChatGPT would fail questions along the lines of "What's heavier, a pound of feathers or three pounds of steel?" because it had seen the normal variation of the riddle with equal weights so many times. It has no concept of one being smaller than three. It just "knows" the pattern of the "correct" response.
It no longer fails that "trick", but there's significant evidence that OpenAI has set up custom handling for that riddle over top of the actual LLM, as it doesn't take much work to find similar ways to trip it up by using slightly modified versions of classic riddles.
A lot of supporters will counter "Well I just ask it to tell the truth, or tell it that it's wrong, and it corrects itself", but I've seen plenty of anecdotes in the opposite direction, with ChatGPT insisting that it's hallucination was fact. It doesn't have any concept of true or false.
The shame of it is that despite this limitation LLMs have very real practical uses that, much like cryptocurrencies and NFTs did to blockchain, are being undercut by hucksters.
Tesla has done the same thing with autonomous driving too. They claimed to be something they're not (fanboys don't @ me about semantics) and made the REAL thing less trusted and take even longer to come to market.
Drives me crazy.
Yup, and I hate that.
I really would like to one day just take road trips everywhere without having to actually drive.
Right? Waymo is already several times safer than humans and tesla's garbage, yet municipalities keep refusing them. Trust is a huge problem for them.
And yes, haters, I know that they still have problems in inclement weather but that's kinda the point: we would be much further along if it weren't for the unreasonable hurdles they keep facing because of fear created by Tesla
Hadn't heard of this. Thanks!
For road trips (i.e. interstates and divided highways), GM’s Super Cruise is pretty much there unless you go through a construction zone. I just went from Atlanta to Knoxville without touching the steering wheel once.
I'll look into that when my Kia passes away. Thank you!
Trains are really good for that
You can't road trip in a train.
I love that example. Microsoft's Copilot (based on GTP-4) immediately doesn't disappoint:
It's annoying that for many things, like basic programming tasks, it manages to generate reasonable output that is good enough to goat people into trusting it, yet hallucinates very obviously wrong stuff or follows completely insane approaches on anything off the beaten path. Every other day, I have to spend an hour to justify to a coworker why I wrote code this way when the AI has given him another "great" suggestion, like opening a hidden window with an UI control to query a database instead of going through our ORM.
Yeah, see, one very popular modern religion (without official status or need for one to explicitly identify with id, but really influential) is exactly about "a wonderful invention" spontaneously emerging in the hands of some "genius" who "thinks differently".
Most people put this idea far above reaching your goal after making myriad of small steps, not skipping a single one.
They also want a magic wand.
The fans of "AI" today are deep inside simply luddites. They want some new magic to emerge to destroy the magic they fear.
Lol, the AI haters are luddites, not the AI supporters. AI is the present and future, and just because it isn't perfect doesn't mean it's not good enough for many things. And it will continue to get better, most likely.
You should try and understand that it's not magic, it's a very specific set of actions aimed at a very specific result with very specific area of application. Every part of it is clear. There's no uncharted area where we don't know at all what happens. Engineering doesn't work like that anywhere except action movies.
By the same logic as that "it isn't perfect" a plane made of grass by cargo cult members can suddenly turn into a real aircraft.
And it won't magically become something above it, if that's what you mean by "get better".
For the same reason we still don't have a computer virus which developed conscience, and we won't.
And if you think otherwise then you are what I described.
This is not true. If you train these models on game of Othello, they'll keep a state of the world internally and use that to predict the next move played (1). To execute addition and multiplication they are executing an algorithm on which they were not explicitly trained (although the gpt family is surprisingly bad at it, due to a badly designed tokenizer).
These models are still pretty bad at most reasoning tasks. But training on predicting the next word is a perfectly valid strategy, after all the best way to predict what comes after the "=" in 1432 + 212 = is to do the addition.
Yep the hallucinations issue happens even in GPT4, in my experience certain topics can bring about potential hallucinations more than others but if ChatGPT (even with GPT4 or whatever other advanced version of it) gets “stuck” on believing its hallucinations the only way to convince it is literally plainly stating the part that’s wrong and directing it to search Bing or the internet some other way specifically for that. Otherwise you just let out a sigh and start a new chat. If you spend too much time negotiating with it that wastes tokens anyway so the chat becomes bloated and it forgets stuff from earlier in the chat, not to mention technically you’re paying for being able to use the more advanced model anyway and yeah basically the more you treat the chat like a normal conversation the worse it is with AI. I guess that’s why “prompt engineering” was or is a thing, whether legitimate or not.
I did also importantly note that if you pay for credits with OpenAI to use their “playground” to create a specifically customized GPT4 adjusting temperature and response types it takes getting used to because it is WAY different than ChatGPT regardless of which version of GPT you have it set to. It actually kind of blew me away with how much better it “””understood””” software development but the issue is you kind of have to set up chats yourself it’s more complex and you pay per token so mistakes cost you. If it wasn’t such a pain and I had a specific use case I would definitely rather pay for OpenAI credits as needed than their bs “Plus” $20/month subscription for nerfed GPT4 as a chatbot.
