Generative artificial intelligence Generative artificial intelligence (Generative AI, GenAI,[1] or GAI) is a subfield of artificial intelligence that uses generative models to produce text, images, videos, or other forms of data.[2][3][4] These models learn the underlying patterns and structures of their training data and use them to produce new data[5][6] based on the input, which often comes in the form of natural language prompts.[7][8] Generative AI tools have become more common since an "AI

tive AI tools have become more common since an "AI boom" in the 2020s. This boom was made possible by improvements in transformer-based deep neural networks, particularly large language models (LLMs). Major tools include chatbots such as ChatGPT, DeepSeek, Copilot, Gemini, Llama, and Grok; text-to-image artificial intelligence image generation systems such as Stable Diffusion, Midjourney, and DALL-E; and text-to-video AI generators such as Sora.[9][10][11][12] Technology companies developing gen

9][10][11][12] Technology companies developing generative AI include OpenAI, Anthropic, Microsoft, Google, DeepSeek, and Baidu.[7][13][14] Generative AI has raised many ethical questions. It can be used for cybercrime, or to deceive or manipulate people through fake news or deepfakes.[15] Even if used ethically, it may lead to mass replacement of human jobs.[16] The tools themselves have been criticized as violating intellectual property laws, since they are trained on and emulate copyrighted wo

Markov published his first paper on the topic in 1906,[27][28] and analyzed the pattern of vowels and consonants in the novel Eugeny Onegin using Markov chains. Once a Markov chain is learned on a text corpus, it can then be used as a probabilistic text generator.[29][30] Computers were needed to go beyond Markov chains. By the early 1970s, Harold Cohen was creating and exh

ds such as state space search and constraint satisfaction and were a "relatively mature" technology by the early 1990s. They were used to generate crisis action plans for military use,[34] process plans for manufacturing[32] and decision plans such as in prototype autonomous spacecraft.[35] Generative neural nets (2014-2019) [edit]Since inception, the field of machine learning has used both discriminative models and generative models to model and predict data. Beginning in the late 2000s, the em

predict data. Beginning in the late 2000s, the emergence of deep learning drove progress, and research in image classification, speech recognition, natural language processing and other tasks. Neural networks in this era were typically trained as discriminative models due to the difficulty of generative modeling.[36] In 2014, advancements such as the variational autoencoder and generative adversarial network produced the first practical deep neural networks capable of learning generative models
https://en.wikipedia.org/wiki/Generative_artificial_intelligence#8
ral networks capable of learning generative models, as opposed to discriminative ones, for complex data such as images. These deep generative models were the first to output not only class labels for images but also entire images. In 2017, the Transformer network enabled advancements in generative models compared to older Long-Short Term Memory models,[37] leading to the first generative pre-trained transformer (GPT), known as GPT-1, in 2018.[38] This was followed in 2019 by GPT-2, which demonst

This was followed in 2019 by GPT-2, which demonstrated the ability to generalize unsupervised to many different tasks as a Foundation model.[39] The new generative models introduced during this period allowed for large neural networks to be trained using unsupervised learning or semi-supervised learning, rather than the supervised learning typical of discriminative models. Unsupervised learning removed the need for humans to manually label data, allowing for larger networks to be trained.[40] G

In late 2022, the public release of ChatGPT revolutionized the accessibility and application of generative AI for general-purpose text-based tasks.[46] The system's ability to engage in natural conversations, generate creative content, assist with coding, and perform various analytical tasks captured global attention and s

s analytical tasks captured global attention and sparked widespread discussion about AI's potential impact on work, education, and creativity.[47] In March 2023, GPT-4's release represented another jump in generative AI capabilities. A team from Microsoft Research controversially argued that it "could reasonably be viewed as an early (yet still incomplete) version of an artificial general intelligence (AGI) system."[48] However, this assessment was contested by other scholars who maintained that

survey by SAS and Coleman Parkes Research, China has emerged as a global leader in generative AI adoption, with 83% of Chinese respondents using the technology, exceeding both the global average of 54% and the U.S. rate of 65%. This leadership is further evidenced by China's intellectual property developments in the field, with a UN report revealing that Chinese entities filed over 38,000 generative AI patents from 2014 to 2023, substantially surpassing the United States in patent applications.[

Generative AI can be either unimodal or multimodal; unimodal systems take only one type of input, whereas multimodal systems can take more than one type of input.[58] For example, one version of OpenAI's GPT-4 accepts both text and image inputs.[59] Generative AI has made its appearance in a wide variety of industries, radically changing the dynamics of content creation, analysis, and delivery. In healthcare,[60] generative AI is instrumental in accelerating drug discovery by creating molecul

in accelerating drug discovery by creating molecular structures with target characteristics[61] and generating radiology images for training diagnostic models. This extraordinary ability not only enables faster and cheaper development but also enhances medical decision-making. In finance, generative AI is invaluable as it generates datasets to train models and automates report generation with natural language summarization capabilities. It automates content creation, produces synthetic financial

Collectively, these technologies enhance efficiency, reduce operational costs, and support data-driven decision-making in financial institutions.[62] The media industry makes use of generative AI for numerous creative activities such as music composition, scriptwriting, video editing, and digital art. The educational sector is impacted as well, since the tools

Both the teachers and the learners benefit from AI-based platforms that suit various learning patterns.[63] Text and software code [edit]Jung believed that the shadow self is not entirely evil or bad, but rather a potential source of creativity and growth.

They are capable of natural language processing, machine translation, and natural language generation and can be used as foundation models for other tasks.[65] Data sets include BookCorpus, Wikipedia, and others (see List of text corpora). In addition to natural language text, large language models can be trained on programming language text, allowing them to generate source code for new computer programs.[66] Examples include OpenAI Codex, Tabnine,

An early pioneer in this field was 15.ai, launched in March 2020, which demonstrated the ability to clone character voices using as little as 15 seconds of training data.[71] The website gained widespread attention for its ability to generate emotionally expressive speech for various fictional characters, though it was later taken offline in 2022 due to copyright concerns.[72][73][74] C

Audio deepfakes of music lyrics hav

Music artist's instrumentals and lyrics are copyrighted but their voices are not protected from regenerative AI yet, raising a debate about whether artists should get royalties from audio deepfakes.[78] Many AI music generators have been created that can be generated using a text phrase, genre options, and looped libraries of bars and riffs.[79] Video [edit]Gen

Examples include Sora by OpenAI,[12] Runway,[80] and Make-A-Video by Meta Platforms.[81] Robotics [edit]Generative AI can also be trained on the motions of a robotic system to generate new trajectories for motion planning or navigation. For example, UniPi from Google Research uses prompts like "pick up blue bowl" or "wipe plate with ye

and text-to-video products such as Runway Gen-2.[88] Generative AI features have been integrated into a variety of existing commercially available products such as Microsoft Office (Microsoft Copilot),[89] Google Photos,[90] and the Adobe Suite (Adobe Firefly).[91] Many generative AI models are also available as open-source software, including Stable Diffusion and the LLaMA[92] language model. Smaller generative AI models with up to a few billion parameters can run on smartphones, embedded devic

parameters can run on smartphones, embedded devices, and personal computers. For example, LLaMA-7B (a version with 7 billion parameters) can run on a Raspberry Pi 4[93] and one version of Stable Diffusion can run on an iPhone 11.[94] Larger models with tens of billions of parameters can run on laptop or desktop computers. To achieve an acceptable speed, models of this size may require accelerators such as the GPU chips produced by NVIDIA and AMD or the Neural Engine included in Apple silicon pr

For example, the 65 billion parameter version of LLaMA can be configured to run on a desktop PC.[95] The advantages of running generative AI locally include protection of privacy and intellectual property, and avoidance of rate limiting and censorship. The subreddit r/LocalLLaMA in particular focuses on using consumer-grade gaming graphics cards[96] through such techniques as compression. That forum is one of only two sources Andrej Karpa

In 2022, the United States New Export Controls on Advanced Computing and Semiconductors to China imposed restrictions on exports to China of GPU and AI accelerator chips used for generative AI.[100] Chips such as the NVIDIA A800[101] and the Biren Technology BR104[102] were developed to meet the requirements of the sanctions. There is free software on the market capable of recognizing text generated by generative artificial i

ognizing text generated by generative artificial intelligence (such as GPTZero), as well as images, audio or video coming from it.[103] Potential mitigation strategies for detecting generative AI content include digital watermarking, content authentication, information retrieval, and machine learning classifier models.[104] Despite claims of accuracy, both free and paid AI text detectors have frequently produced false positives, mistakenly accusing students of submitting AI-generated work.[105][

ng students of submitting AI-generated work.[105][106] Generative models and training techniques [edit]Generative adversarial networks [edit]Generative adversarial networks (GANs) are an influential generative modeling technique. GANs consist of two neural networks—the generator and the discriminator—trained simultaneously in a competitive setting. The generator creates synthetic data by transforming random noise into samples that resemble the training dataset. The discriminator is trained to di
https://en.wikipedia.org/wiki/Generative_artificial_intelligence#41
aining dataset. The discriminator is trained to distinguish the authentic data from synthetic data produced by the generator.[107] The two models engage in a minimax game: the generator aims to create increasingly realistic data to "fool" the discriminator, while the discriminator improves its ability to distinguish real from fake data. This continuous training setup enables the generator to produce high-quality and realistic outputs.[108] Variational autoencoders [edit]Variational autoencoders
https://en.wikipedia.org/wiki/Generative_artificial_intelligence#42
ional autoencoders [edit]Variational autoencoders (VAEs) are deep learning models that probabilistically encode data. They are typically used for tasks such as noise reduction from images, data compression, identifying unusual patterns, and facial recognition. Unlike standard autoencoders, which compress input data into a fixed latent representation, VAEs model the latent space as a probability distribution,[109] allowing for smooth sampling and interpolation between data points. The encoder ("r

interpolation between data points. The encoder ("recognition model") maps input data to a latent space, producing means and variances that define a probability distribution. The decoder ("generative model") samples from this latent distribution and attempts to reconstruct the original input. VAEs optimize a loss function that includes both the reconstruction error and a Kullback–Leibler divergence term, which ensures the latent space follows a known prior distribution. VAEs are particularly suit
https://en.wikipedia.org/wiki/Generative_artificial_intelligence#44
own prior distribution. VAEs are particularly suitable for tasks that require structured but smooth latent spaces, although they may create blurrier images than GANs. They are used for applications like image generation, data interpolation and anomaly detection. Transformers [edit]Transformers became the foundation for many powerful generative models, most notably the generative pre-trained transformer (GPT) series developed by OpenAI. They marked a major shift in natural language processing by
https://en.wikipedia.org/wiki/Generative_artificial_intelligence#45
d a major shift in natural language processing by replacing traditional recurrent and convolutional models.[110] This architecture allows models to process entire sequences simultaneously and capture long-range dependencies more efficiently. The self-attention mechanism enables the model to capture the significance of every word in a sequence when predicting the subsequent word, thus improving its contextual understanding. Unlike recurrent neural networks, transformers process all the tokens in
https://en.wikipedia.org/wiki/Generative_artificial_intelligence#46
networks, transformers process all the tokens in parallel, which improves the training efficiency and scalability. Transformers are typically pre-trained on enormous corpora in a self-supervised manner, prior to being fine-tuned. Law and regulation [edit]In the United States, a group of companies including OpenAI, Alphabet, and Meta signed a voluntary agreement with the Biden administration in July 2023 to watermark AI-generated content.[111] In October 2023, Executive Order 14110 applied the D
https://en.wikipedia.org/wiki/Generative_artificial_intelligence#47
October 2023, Executive Order 14110 applied the Defense Production Act to require all US companies to report information to the federal government when training certain high-impact AI models.[112][113] In the European Union, the proposed Artificial Intelligence Act includes requirements to disclose copyrighted material used to train generative AI systems, and to label any AI-generated output as such.[114][115] In China, the Interim Measures for the Management of Generative AI Services introduce
https://en.wikipedia.org/wiki/Generative_artificial_intelligence#48
the Management of Generative AI Services introduced by the Cyberspace Administration of China regulates any public-facing generative AI. It includes requirements to watermark generated images or videos, regulations on training data and label quality, restrictions on personal data collection, and a guideline that generative AI must "adhere to socialist core values".[116][117] Copyright [edit]Training with copyrighted content [edit]Generative AI systems such as ChatGPT and Midjourney are trained o

stems such as ChatGPT and Midjourney are trained on large, publicly available datasets that include copyrighted works. AI developers have argued that such training is protected under fair use, while copyright holders have argued that it infringes their rights.[118] Proponents of fair use training have argued that it is a transformative use and does not involve making copies of copyrighted works available to the public.[118] Critics have argued that image generators such as Midjourney can create
https://en.wikipedia.org/wiki/Generative_artificial_intelligence#50
at image generators such as Midjourney can create nearly-identical copies of some copyrighted images,[119] and that generative AI programs compete with the content they are trained on.[120] As of 2024, several lawsuits related to the use of copyrighted material in training are ongoing. Getty Images has sued Stability AI over the use of its images to train Stable Diffusion.[121] Both the Authors Guild and The New York Times have sued Microsoft and OpenAI over the use of their works to train ChatG
https://en.wikipedia.org/wiki/Generative_artificial_intelligence#51
OpenAI over the use of their works to train ChatGPT.[122][123] Copyright of AI-generated content [edit]A separate question is whether AI-generated works can qualify for copyright protection. The United States Copyright Office has ruled that works created by artificial intelligence without any human input cannot be copyrighted, because they lack human authorship.[124] Some legal professionals have suggested that Naruto v. Slater (2018), in which the U.S. 9th Circuit Court of Appeals held that no
https://en.wikipedia.org/wiki/Generative_artificial_intelligence#52
the U.S. 9th Circuit Court of Appeals held that non-humans cannot be copyright holders of artistic works, could be a potential precedent in copyright litigation over works created by generative AI.[125] However, the office has also begun taking public input to determine if these rules need to be refined for generative AI.[126] In January 2025, the United States Copyright Office (USCO) released extensive guidance regarding the use of AI tools in the creative process, and established that "...gene

he creative process, and established that "...generative AI systems also offer tools that similarly allow users to exert control. [These] can enable the user to control the selection and placement of individual creative elements. Whether such modifications rise to the minimum standard of originality required under Feist will depend on a case-by-case determination. In those cases where they do, the output should be copyrightable"[127] Subsequently, the USCO registered the first visual artwork to
https://en.wikipedia.org/wiki/Generative_artificial_intelligence#54
, the USCO registered the first visual artwork to be composed of entirely AI-generated materials, titled "A Single Piece of American Cheese".[128] Concerns [edit]The development of generative AI has raised concerns from governments, businesses, and individuals, resulting in protests, legal actions, calls to pause AI experiments, and actions by multiple governments. In a July 2023 briefing of the United Nations Security Council, Secretary-General António Guterres stated "Generative AI has enormou

António Guterres stated "Generative AI has enormous potential for good and evil at scale", that AI may "turbocharge global development" and contribute between $10 and $15 trillion to the global economy by 2030, but that its malicious use "could cause horrific levels of death and destruction, widespread trauma, and deep psychological damage on an unimaginable scale".[129] In addition, generative AI has a significant carbon footprint.[130][131] Job losses [edit]From the early days of the developme
https://en.wikipedia.org/wiki/Generative_artificial_intelligence#56
losses [edit]From the early days of the development of AI, there have been arguments put forward by ELIZA creator Joseph Weizenbaum and others about whether tasks that can be done by computers actually should be done by them, given the difference between computers and humans, and between quantitative calculations and qualitative, value-based judgements.[133] In April 2023, it was reported that image generation AI has resulted in 70% of the jobs for video game illustrators in China being lost.[1
https://en.wikipedia.org/wiki/Generative_artificial_intelligence#57
for video game illustrators in China being lost.[134][135] In July 2023, developments in generative AI contributed to the 2023 Hollywood labor disputes. Fran Drescher, president of the Screen Actors Guild, declared that "artificial intelligence poses an existential threat to creative professions" during the 2023 SAG-AFTRA strike.[136] Voice generation AI has been seen as a potential challenge to the voice acting sector.[137][138] The intersection of AI and employment concerns among underrepresen
https://en.wikipedia.org/wiki/Generative_artificial_intelligence#58
of AI and employment concerns among underrepresented groups globally remains a critical facet. While AI promises efficiency enhancements and skill acquisition, concerns about job displacement and biased recruiting processes persist among these groups, as outlined in surveys by Fast Company. To leverage AI for a more equitable society, proactive steps encompass mitigating biases, advocating transparency, respecting privacy and consent, and embracing diverse teams and ethical considerations. Stra

ing diverse teams and ethical considerations. Strategies involve redirecting policy emphasis on regulation, inclusive design, and education's potential for personalized teaching to maximize benefits while minimizing harms.[139] Racial and gender bias [edit]Generative AI models can reflect and amplify any cultural bias present in the underlying data. For example, a language model might assume that doctors and judges are male, and that secretaries or nurses are female, if those biases are common i
https://en.wikipedia.org/wiki/Generative_artificial_intelligence#60
or nurses are female, if those biases are common in the training data.[140] Similarly, an image model prompted with the text "a photo of a CEO" might disproportionately generate images of white male CEOs,[141] if trained on a racially biased data set. A number of methods for mitigating bias have been attempted, such as altering input prompts[142] and reweighting training data.[143] Deepfakes [edit]Deepfakes (a portmanteau of "deep learning" and "fake"[144]) are AI-generated media that take a per

fake"[144]) are AI-generated media that take a person in an existing image or video and replace them with someone else's likeness using artificial neural networks.[145] Deepfakes have garnered widespread attention and concerns for their uses in deepfake celebrity pornographic videos, revenge porn, fake news, hoaxes, health disinformation, financial fraud, and covert foreign election interference.[146][147][148][149][150][151][152] This has elicited responses from both industry and government to
https://en.wikipedia.org/wiki/Generative_artificial_intelligence#62
ed responses from both industry and government to detect and limit their use.[153][154] In July 2023, the fact-checking company Logically found that the popular generative AI models Midjourney, DALL-E 2 and Stable Diffusion would produce plausible disinformation images when prompted to do so, such as images of electoral fraud in the United States and Muslim women supporting India's Hindu nationalist Bharatiya Janata Party.[155][156] In April 2024, a paper proposed to use blockchain (distributed
