Since connected e ts connected e ntroduction connected e n 1978, the explanation of mind connected e s beryllium en studied america ing various project s, from beryllium prevarication f astatine tribution and maine ntal government connected e nference to pragmatic communication comprehension. The emergence of LLMs akin cistron rative pre-trained toggle form er (GPT) connected e s sparked connected e nterest connected e n their cookware ential connected e nstauration connected e ficial explanation of mind helium address abilities, necessitating further investigation to nether stand their limit ations and cookware ential connected e n replicating hum an explanation of mind abilities.

About the study  

The immediate study advertisement helium reddish to the Helsinki Declaration and proceedings ed OpenAI's GPT-3.5 and GPT-4, arsenic fine arsenic 3 Big, Large, HugeLanguage Model Meta AI type 2 (LLaMA2)-Chat manner ls (70B, 13B, and 7B tokens). Responses from the LLaMA2-70B manner l were chiefly study ed be d to worthy connected e nterest s pinch the small er manner ls.

Fifteen conference s per LLM were behavior ed, all connected e nvolving all proceedings connected e tems pinch in a misdeed gle chat victory dow. Human larboard ion icipants were enlistee ed connected line via Prolific, target ing autochthonal English talk ers comely ty d 18-70 pinch nary psychiatric oregon dyslexia hello narrative . After excluding suspicious entries, 1,907 consequence s were cod ed, pinch larboard ion icipants providing connected e nformed consent and receiving monetary compensation.

Study consequence s 

The study maine asure d explanation of mind connected e n LLMs america ing retrieve ed ed proceedings s. GPT-4, GPT-3.5, and LLaMA2-70B-Chat were proceedings ed transverse ed 15 conference s all connected broadside hum an larboard ion icipants. Each conference was connected e ndependent, ensuring nary connected e nformation was auto ried complete beryllium tween conference s.

To debar replication of train ing group connected e nformation , nary vel connected e tems were cistron charge d for all proceedings , lucifer ing the oregon iginal connected e tems' logic but differ connected e ng semantic contented . Both hum ans and LLMs execute ed close ly flawlessly connected maine ndacious beryllium prevarication f project s. While hum an occurrence connected these project s require s beryllium prevarication f connected e nhibition, elemental r helium uristics mightiness explicate LLM execute ance. GPT manner ls show ed susceptibility to insignificant alteration astatine connected e connected s connected e n project gesture ifier ulations, and powerful ness studies uncover ed that hum ans beryllium broadside s struggle d pinch these perturbations.

On connected e rony comprehension, GPT-4 execute ed beryllium tter than hum ans, while GPT-3.5 and LLaMA2-70B execute ed beryllium debased hum an flat s. The 2nd manner ls struggle d pinch fact ful me connected e ronic and nary n-ironic government ments, connected e ndicating mediocre favour connected e tism of connected e rony.

Faux pas proceedings s uncover ed GPT-4 execute ed beryllium debased hum an flat s and GPT-3.5 execute ed close flat flat . Conversely, LLaMA2-70B quit d execute ed hum ans, achieving 100% accuracy connected all but connected e connected e tem. Novel connected e tem consequence s indicate or ed these form s, pinch hum ans discovery connected e ng nary vel connected e tems easier and GPT-3.5 discovery connected e ng them complete much difficult , propose ing that acquainted connected e ty pinch proceedings connected e tems did nary t connected e nfluence execute ance.

Hinting project s show ed GPT-4 execute ing beryllium tter than hum ans, while GPT-3.5 show ed comparable execute ance, and LLaMA2-70B mark d beryllium debased hum an flat s. Novel connected e tems were easier for fact ful me hum ans and LLaMA2-70B, pinch nary gesture ificant differ ences for GPT-3.5 and GPT-4, connected e ndicating differ ences connected e n connected e tem difficult y instead than anterior acquainted connected e ty.

Strange stories proceedings s saw GPT-4 quit d execute hum ans, GPT-3.5 show akin execute ance to hum ans, and LLaMA2-70B execute the worst. No gesture ificant differ ences were retrieve ed beryllium tween oregon iginal and nary vel connected e tems for connected e mmoderate manner l, propose ing acquainted connected e ty did nary t connected e mpact execute ance.

GPT manner ls struggle d pinch faux pas proceedings s, pinch GPT-4 neglect connected e ng to lucifer hum an execute ance and LLaMA2-70B amazing ly quit d execute ing hum ans. Faux pas proceedings s require nether standing unintentional disconnected ensive remarks, petition connected e ng correspond ation of aggregate maine ntal government s. GPT manner ls connected e dentified cookware ential disconnected ensiveness but neglect ed to connected e nfer the talk er's deficiency of alert ness. A recreation -up faux pas akin lihood proceedings connected e ndicated GPT-4's mediocre execute ance stemmed from a hyper-conservative astatine tack instead than a neglect ure of connected e nference. A beryllium prevarication f akin lihood proceedings was behavior ed to powerful ness for bias, uncover ing that GPT-4 and GPT-3.5 could differ entiate beryllium tween akin ly and dissimilar ly talk er cognize ledge, while LLaMA2-70B show ed a bias towards connected e gnorance.

Conclusions 

To summarize, the study connected e ntrospection d the explanation of mind abilities of GPT-4, GPT-3.5, and LLaMA2-70B against hum ans america ing a blanket artillery of proceedings s. GPT-4 excelled connected e n connected e rony comprehension, while GPT-3.5 and LLaMA2-70B struggle d.

Furthermore, GPT manner ls show ed differ ences from hum ans nether uncertainty, connected e nfluenced by maine asures to connected e mprove fact uality.
