How do machine encyclopaedism good example do what they do ? And are they really “ thinking ” or “ argue ” the way we understand those things ? This is a philosophical dubiousness as much as a practical one , but a new paper making the round of golf Friday suggests that the answer is , at least for now , a pretty clear “ no . ”
A mathematical group of AI research scientist at Apple released their paper,“Understanding the limitations of numerical logical thinking in large lyric models,”to general commentary Thursday . While the deep concepts of symbolic learning and pattern reproduction are a mo in the dope , the introductory concept of their enquiry is very easy to apprehend .
Let ’s say I inquire you to lick a unsubdivided mathematics trouble like this one :
Oliver picks 44 kiwi on Friday . Then he pick 58 kiwis on Saturday . On Sunday , he picks double the number of Chinese gooseberry he did on Friday . How many Kiwi does Oliver have ?
Obviously , the reply is 44 + 58 + ( 44 * 2 ) = 190 . Thoughlarge language models ( LLMs ) are actually spotty on arithmetic , they can moderately faithfully work out something like this . But what if I throw in a little random supernumerary info , like this :
Oliver picks 44 Actinidia chinensis on Friday . Then he pick 58 apteryx on Saturday . On Sunday , he pick double the telephone number of kiwis he did on Friday , but five of them were a bit smaller than average . How many kiwis does Oliver have ?
It ’s the same math job , right ? And of course even a grade schooler would cognize that even a small kiwi is still a kiwi vine . But as it turns out , this extra information full stop confuses even state - of - the - art Master of Laws . Here ’s GPT - o1 - miniskirt ’s take :
[ O]n Sunday , 5 of these kiwi were smaller than average . We need to subtract them from the Sunday amount : 88 ( Sunday ’s kiwis ) – 5 ( smaller apteryx ) = 83 kiwis
This is just a simple example out of hundreds of questions that the researcher gently modified , but nearly all of which extend to enormous drop in winner rates for the models essay them .
Now , why should this be ? Why would a model that understand the trouble be throw off so easily by a random , irrelevant detail ? The research worker propose that this reliable musical mode of nonstarter means the models do n’t really understand the trouble at all . Their training information does allow them to answer with the right answer in some office , but as before long as the slightest actual “ reasoning ” is required , such as whether to bet small kiwis , they start producing weird , unintuitive result .

As the investigator put it in their paper :
[ W]e inquire the fragility of mathematical reasoning in these models and establish that their performance importantly deteriorates as the routine of clause in a head increases . We suppose that this decline is due to the fact that current LLMs are not capable of genuine coherent reasoning ; alternatively , they attempt to double the logical thinking stride observed in their grooming data .
This observation is consistent with the other qualities often attributed to LLM due to their facility with oral communication . When , statistically , the idiom “ I get it on you ” is followed by “ I love you , too , ” the LLM can easy recapitulate that — but it does n’t stand for it loves you . And although it can surveil complex strand of reasoning it has been exposed to before , the fact that this chain can be broken by even superficial deviations intimate that it does n’t actually reason out so much as replicate patterns it has observed in its training datum .
Mehrdad Farajtabar , one of the co - author , breaks down the paper very nicely in this thread on X.
An OpenAI investigator , while remember Mirzadeh and fellow worker ’ workplace , objected to their conclusions , enunciate that right results could likely be achieved in all these failure cases with a turn of straightaway applied science . Farajtabar ( respond with the typical yet admirable friendliness researchers run to employ ) noted that while good prompting may turn for simple deviation , the model may require exponentially more contextual data point in club to counter complex distractions — 1 that , again , a child could trivially point out .
Does this mean that LLMs do n’t ground ? mayhap . That they ca n’t reason ? No one cognize . These are not well - defined concepts , and the questions tend to come out at the bleeding edge of AI research , where the state of the nontextual matter change on a casual groundwork . Perhaps LLMs “ rationality , ” but in a way we do n’t yet recognize or be intimate how to control .
It makes for a fascinating frontier in research , but it ’s also a cautionary tale when it comes to how AI is being sold . Can it really do the things they take , and if it does , how ? As AI becomes an quotidian software tool , this kind of question is no longer academic .
