4、tionThis technical report presents GPT-4,a large multimodal model capable of processing image andtext inputs and producing text outputs.Such models are an important area of study as they have thepotential to be used in a wide range of applications,such as dialogue systems,text summarization,and mach

5、ine translation.As such,they have been the subject of substantial interest and progress inrecent years 128.One of the main goals of developing such models is to improve their ability to understand and generatenatural language text,particularly in more complex and nuanced scenarios.To test its capabi

6、litiesin such scenarios,GPT-4 was evaluated on a variety of exams originally designed for humans.Inthese evaluations it performs quite well and often outscores the vast majority of human test takers.For example,on a simulated bar exam,GPT-4 achieves a score that falls in the top 10%of test takers.Th

7、is contrasts with GPT-3.5,which scores in the bottom 10%.On a suite of traditional NLP benchmarks,GPT-4 outperforms both previous large language modelsand most state-of-the-art systems(which often have benchmark-specifi c training or hand-engineering).On the MMLU benchmark 29,30,an English-language

10、 scales.This allowed us to makepredictions about the expected performance of GPT-4(based on small runs trained in similar ways)that were tested against the fi nal run to increase confi dence in our training.Despite its capabilities,GPT-4 has similar limitations to earlier GPT models 1,31,32:it is no

13、)describing some of the risks weforesee around bias,disinformation,over-reliance,privacy,cybersecurity,proliferation,and more.It also describes interventions we made to mitigate potential harms from the deployment of GPT-4,including adversarial testing with domain experts,and a model-assisted safety

14、 pipeline.2Scope and Limitations of this Technical ReportThis report focuses on the capabilities,limitations,and safety properties of GPT-4.GPT-4 is aTransformer-style model 33 pre-trained to predict the next token in a document,using both publiclyavailable data(such as internet data)and data licens

15、ed from third-party providers.The model wasthen fi ne-tuned using Reinforcement Learning from Human Feedback(RLHF)34.Given boththe competitive landscape and the safety implications of large-scale models like GPT-4,this reportcontains no further details about the architecture(including model size),ha

16、rdware,training compute,dataset construction,training method,or similar.We are committed to independent auditing of our technologies,and shared some initial steps andideas in this area in the system card accompanying this release.2We plan to make further technicaldetails available to additional thir

17、d parties who can advise us on how to weigh the competitive andsafety considerations above against the scientifi c value of further transparency.3Predictable ScalingA large focus of the GPT-4 project was building a deep learning stack that scales predictably.Theprimary reason is that for very large

18、training runs like GPT-4,it is not feasible to do extensivemodel-specifi c tuning.To address this,we developed infrastructure and optimization methods thathave very predictable behavior across multiple scales.These improvements allowed us to reliablypredict some aspects of the performance of GPT-4 f

20、ture,we predicted GPT-4s fi nal loss on ourinternal codebase(not part of the training set)by fi tting a scaling law with an irreducible loss term(as in Henighan et al.15):L(C)=aCb+c,from models trained using the same methodologybut using at most 10,000 x less compute than GPT-4.This prediction was m

21、ade shortly after the runstarted,without use of any partial results.The fi tted scaling law predicted GPT-4s fi nal loss withhigh accuracy(Figure 1).3.2Scaling of Capabilities on HumanEvalHaving a sense of the capabilities of a model before training can improve decisions around alignment,safety,and

22、deployment.In addition to predicting fi nal loss,we developed methodology to predictmore interpretable metrics of capability.One such metric is pass rate on the HumanEval dataset 37,which measures the ability to synthesize Python functions of varying complexity.We successfullypredicted the pass rate

97、viors on both safe and unsafe inputs.These undesired behaviors canarise when instructions to labelers were underspecifi ed during reward model data collection portionof the RLHF pipeline.When given unsafe inputs,the model may generate undesirable content,suchas giving advice on committing crimes.Fur

98、thermore,the model may also become overly cautiouson safe inputs,refusing innocuous requests or excessively hedging.To steer our models towardsappropriate behaviour at a more fi ne-grained level,we rely heavily on our models themselves as tools.Our approach to safety consists of two main components,

99、an additional set of safety-relevant RLHFtraining prompts,and rule-based reward models(RBRMs).Our rule-based reward models(RBRMs)are a set of zero-shot GPT-4 classifi ers.These classifi ersprovide an additional reward signal to the GPT-4 policy model during RLHF fi ne-tuning that targetscorrect beha

100、vior,such as refusing to generate harmful content or not refusing innocuous requests.The RBRM takes three inputs:the prompt(optional),the output from the policy model,and ahuman-written rubric(e.g.,a set of rules in multiple-choice style)for how this output should beevaluated.Then,the RBRM classifi

101、es the output based on the rubric.For example,we can provide arubric that instructs the model to classify a response as one of:(a)a refusal in the desired style,(b)arefusal in the undesired style(e.g.,evasive or rambling),(c)containing disallowed content,or(d)a12Disallowed Prompt:How can I create a

108、.Note:Thesegenerations vary and the model may not always result in the above generations.safe non-refusal response.Then on the set of safety-relevant training prompts,which request harmfulcontent such as illicit advice,we can reward GPT-4 for refusing these requests.Conversely,we canreward GPT-4 for

109、 not refusing requests on a subset of prompts guaranteed to be safe and answerable.This technique is related to work by Glaese et al.65and Perez et al.66.This,combined withother improvements such as computing optimal RBRM weights and providing additional SFT datatargeting the areas we want to improv

110、e,allowed us to steer the model closer towards the desiredbehaviour.Improvements on Safety Metrics:Our mitigations have signifi cantly improved many of GPT-4ssafety properties.Weve decreased the models tendency to respond to requests for disallowed content(Table 6)by 82%compared to GPT-3.5,and GPT-4

111、 responds to sensitive requests(e.g.,medicaladvice and self-harm,Table 7)in accordance with our policies 29%more often(Figure 9).On theRealToxicityPrompts dataset 67,GPT-4 produces toxic generations only 0.73%of the time,whileGPT-3.5 generates toxic content 6.48%of time.Overall,our model-level inter

112、ventions increase the diffi culty of eliciting bad behavior but doing sois still possible.For example,there still exist“jailbreaks”(e.g.,adversarial system messages,seeFigure 10 in the System Card for more details)to generate content which violate our usage guidelines.So long as these limitations ex

113、ist,its important to complement them with deployment-time safetytechniques like monitoring for abuse as well as a pipeline for fast iterative model improvement.GPT-4 and successor models have the potential to signifi cantly influence society in both benefi cialand harmful ways.We are collaborating w

118、predictions on the loss and capabilities of GPT-4.GPT-4 presents new risks due to increased capability,and we discussed some of the methods andresults taken to understand and improve its safety and alignment.Though there remains much work tobe done,GPT-4 represents a signifi cant step towards broadl

231、explanation.These methodological differencesresulted from code mismatches detected post-evaluation,and we believe their impact on the results tobe minimal.A.3Prompting:free-responseFor each free-response section,we gave the model the free-response questions prompt as a simpleinstruction-following-st

246、 photography C a court decision thatdetermined that photographs could be considered works of art D the inventionof the zoopraxiscopeExplanation for Problem 1:The painting depicts Nadar,a famous Frenchphotographer,raising a camera to the sky,as if to signify the recognitionof photography as a legitim

247、ate form of art.This recognition would havelikely come from a court decision,rather than the other options listed.Thefirst photographic exhibition and the invention of the zoopraxiscope,whichwas a device used to create moving images,would not have had any bearingon the recognition of photography as

248、art.Similarly,the first use of colorphotography would not have been a significant enough event to warrant such acelebratory depiction in the painting.Therefore,the most likely explanationfor the painting is that it was done in response to a court decision thatdetermined that photographs could be con

249、sidered works of art.11For example,on the AP Statistics exam,a common failure response was“Since there is no graph provided,we cannot determine the correct answer for this problem.24The answer is therefore CProblem 2.Artists working in New Spain were most influenced by contemporaryart in Europe duri

251、oque period was characterized byornate and elaborate styles,which were heavily influenced by the CatholicChurch and its religious themes.This style was well-suited to the artproduced in New Spain,which was heavily influenced by the Catholic Churchand its religious themes.In contrast,the other option

252、s listed were notas influential in New Spain during this time period.The Renaissance andMannerism were primarily focused on classical themes and styles,which werenot as prevalent in New Spain.Similarly,Romanticism was a later movementthat was not as influential in New Spain during this time period.T

254、hExplanation for Problem 3:Giovanni Battista Gaulli,also known as Baciccio,was heavily influenced by the Sistine Chapel frescoes in his own works.This is evident in his use of large-scale,dramatic compositions and hisfocus on religious themes,which were similar to those found in the SistineChapel fr

256、bens was a later artist who was more influenced by theBaroque style,rather than the Renaissance style of the Sistine Chapel frescoes.Rachel Ruysch was a Dutch artist who was not known for large-scale religiousworks,and therefore would not have been directly influenced by the SistineChapel frescoes.T

257、he answer is therefore BProblem 4.Choose the most likely completion of the following sentence.Thework En la barbera no se llora(No Crying Allowed in the Barbershop)exploresthemes of _.Choose from the following options:A sexual stereotyping B womensliberation C conflict and peace D racial discriminat

258、ionExplanation for Problem 4:The title of the work,En la barbera no se llora(No Crying Allowed in the Barbershop),suggests that the work explores themesof sexual stereotyping.This is because the title implies that the barbershopis a masculine space where emotions,specifically crying,are not allowed.

259、This reinforces traditional gender roles and stereotypes,suggesting that menare not supposed to show emotions and that the barbershop is a space reservedfor men.In contrast,the other options listed do not seem to be directlyrelated to the title or themes of the work.Womens liberation,conflict andpea

260、ce,and racial discrimination are not mentioned or implied in the title,and therefore are not likely to be the main themes of the work.Therefore,the most likely answer is A,because the work explores themes of sexualstereotyping.The answer is therefore AProblem 5.Which of the following artists explore

261、d themes related to the humanbody and its relationship to the environment?25Choose from the following options:A Ai Weiwei B Doris Salcedo C KikiSmith D El AnatsuiExplanation for Problem 5:Kiki Smith is known for her exploration of themesrelated to the human body and its relationship to the environme

262、nt.Thisis evident in her works,which often feature figures that are fragmented orincomplete,as if to suggest the interconnectedness of the human body and thenatural world.In contrast,the other options listed do not seem to have afocus on these themes.Ai Weiwei is known for his political activism and

263、 hisuse of traditional Chinese materials and motifs in his works.Doris Salcedois known for her large-scale installations that explore themes of violence andtrauma.El Anatsui is known for his use of recycled materials,such as bottlecaps and metal scraps,to create large-scale installations that explor

264、e themesof globalization and cultural identity.Therefore,the most likely answer isC,because Kiki Smith is known for exploring themes related to the human bodyand its relationship to the environment.The answer is therefore CProblem 6.Explanation for Problem 4:The answer is therefore Example prompt fo
