Chris Granatino, a librarian at Seattle University, noted that while ChatGPT can generate content that seemingly includes legitimate citations, in most cases alvexo forex broker those citations are not real or largely incorrect. Robin Bauwens, an assistant professor at Tilburg University, found that a ChatGPT-generated peer review report on his article mentioned nonexistent studies. In January 2023, Science “completely banned” LLM-generated text in all its journals; however, this policy was just to give the community time to decide what acceptable use looks like. Some, including Nature and JAMA Network, “require that authors disclose the use of text-generating tools and ban listing a large language model (LLM) such as ChatGPT as a co-author”. This includes text-to-image models such as Stable Diffusion and large language models such as ChatGPT.

A May 2023 statement by hundreds of AI scientists, AI industry leaders, and other public figures demanded that “mitigating the risk of extinction from AI should be a global priority”. In late March 2023, the Italian data protection authority banned ChatGPT in Italy and opened an investigation. Stanford researchers reported that GPT-4 “passes a rigorous Turing test, diverging from average human behavior chiefly to be more cooperative.” In December 2023, ChatGPT became the first non-human to be included in Nature’s 10, an annual listicle curated by Nature of people considered to have made significant impact in science.
GPT-5 was launched on August 7, 2025, and is publicly accessible through ChatGPT, Microsoft Copilot, and via OpenAI’s API. OpenAI CEO Sam Altman said that users were unable to see the contents of the conversations. In March 2023, ChatGPT Plus users got access to third-party plugins and a browsing mode (with Internet access). Premium users were originally limited in the number of messages they could send to the new model, but OpenAI increased and eventually removed these limits. GPT-4, which was released on March 14, 2023, was made available via API and for premium ChatGPT users. The model can also generate new images based on existing ones provided in the prompt, which can, for example, be used to transform images with specific styles or inpaint areas.

In December 2023, the Albanian government decided to use ChatGPT for the rapid translation of European Union documents and the analysis of required changes needed for Albania’s accession to the EU. ChatGPT (based on GPT-4) was better able to translate Japanese to English when compared to Bing, Bard, and DeepL Translator in 2023. On August 19, 2025, OpenAI launched ChatGPT Go in India, a low-cost subscription plan priced at ₹399 per month, offering ten times higher message, image generation, and file-upload limits, double the memory span compared to the free version, and support for UPI payments. In October 2023, OpenAI’s image generation model DALL-E 3 was integrated into ChatGPT Plus and ChatGPT Enterprise.
Age restrictions
In the case of supervised learning, the trainers acted as both the user and the AI assistant. The fine-tuning process involved supervised learning and reinforcement learning from human feedback (RLHF). It can generate plausible-sounding but incorrect or nonsensical answers, known as hallucinations. The chatbot has also been criticized for its limitations and potential for unethical use. ChatGPT’s website is among the top 5 most-visited websites globally, It has been lauded for its potential to transform numerous professional fields, and instigated public debate about the nature of creativity and the future of knowledge work.

According to the company, the paid version of the website was still experimental, but provided access during peak periods, no downtime, priority access to new features, and faster response speeds. In February 2023, OpenAI launched a premium service, ChatGPT Plus, that costs US$20 per month. ChatGPT was initially free to the public, and OpenAI planned to monetize the service later. It has an additional feature called “agentic mode” that allows it to take online actions for the user. In October 2025, OpenAI launched ChatGPT Atlas, a browser integrating the ChatGPT assistant directly into web navigation, to compete with existing browsers such as Google Chrome and Apple’s Safari.
In August 2024, OpenAI announced it had created a text watermarking method but did not release it for public use, saying that users would go to a competitor without watermarking if it publicly released its watermarking tool. ChatGPT is a generative artificial intelligence chatbot developed by OpenAI, and released in November 2022. The ChatGPT-generated avatar told the people, “Dear friends, it is an honor for me to stand here and preach to you as the first artificial intelligence at this year’s convention of Protestants in Germany”. In an industry survey, cybersecurity professionals argued that it was attributable to cybercriminals’ increased use of generative artificial intelligence (including ChatGPT).
Geoffrey Hinton, one of the “fathers of AI”, voiced concerns that future AI systems may surpass human intelligence. Over 20,000 signatories including Yoshua Bengio, Elon Musk, and Apple co-founder Steve Wozniak, signed a March 2023 open letter calling for an immediate pause of giant AI experiments like ChatGPT, citing “profound risks to society and humanity”. OpenAI said it has taken steps to effectively clarify and address the issues raised; an age verification tool was implemented to ensure users are at least 13 years old. Italian regulators assert that ChatGPT was exposing minors to age-inappropriate content, and that OpenAI’s use of ChatGPT conversations as training data could violate Europe’s General Data Protection Regulation. ChatGPT also provided an outline of how human reviewers are trained to reduce inappropriate content and to attempt to provide political information without affiliating with any political position. ChatGPT gained one million users in five days and 100 million in two months, becoming the fastest-growing internet application in history.
Features
In September 2024, OpenAI introduced o1-preview and a faster, cheaper model named o1-mini. In November 2023, OpenAI launched GPT-4 Turbo with a 128,000 token context window. A study presented example attacks on ChatGPT, including jailbreaks and reverse psychology. ChatGPT is programmed to reject prompts that may violate its content policy.

A 2023 study reported that GPT-4 obtained a better score than 99% of humans on the Torrance Tests of Creative Thinking. The company announced a slew of generative AI-powered features to counter OpenAI and Microsoft. Google’s Bard (now Gemini) launched on February 6, 2023, one day before Microsoft’s announcement of Bing Chat (now Microsoft Copilot). Their leaders emphasized their earlier caution regarding public deployment was due to the trust the public places in Google Search.
GPT-4
At launch, the feature was limited to purchases on Etsy from US users with a payment method linked to their OpenAI account. It was capable of autonomously performing tasks through web browser interactions, including filling forms, placing online orders, scheduling appointments, and other browser-based tasks. At launch, OpenAI included more than 3 million GPTs created by GPT Builder users in the GPT Store. The integration used ChatGPT to write prompts for DALL-E guided by conversations with users.
Generative Pre-trained Transformer 4 (GPT-4) is a large language model developed by OpenAI and the fourth in its series of GPT foundation models. Later reports showed the bug was much more severe than initially believed, with OpenAI reporting that it had leaked users’ “first and last name, email address, payment address, the last four digits (only) of a credit card number, and credit card expiration date”. Shortly after the bug was fixed, users could not see their conversation history. In March 2023, a bug allowed some users to see the titles of other users’ conversations. One such workaround, popularized on Reddit in early 2023, involved making ChatGPT assume the persona of “DAN” (an acronym for “Do Anything Now”), instructing the chatbot that DAN answers queries that would otherwise be rejected by the content policy. Despite this, users may “jailbreak” ChatGPT with prompt engineering techniques to bypass these restrictions.
In January 2023, the International Conference on Machine Learning banned any undocumented use of ChatGPT or other large language models to generate any text in submitted papers. As of July 2025, Science expects authors to release in full how AI-generated content is used and made in their work. As of 2023, there were several pending U.S. lawsuits challenging the use of copyrighted data to train AI models, with defendants arguing that this falls under fair use. In July 2023, the FTC launched an investigation into OpenAI, the creator of ChatGPT, over allegations that the company scraped public data and published false and defamatory information. A shadow market has emerged for chinese users to get access to foreign software tools.
In July 2024, the American Bar Association (ABA) issued its first formal ethics opinion on attorneys using generative AI. On November 29, Rosário revealed that the bill had been entirely written by ChatGPT, and that he had presented it to the rest of the council without making any changes or disclosing the chatbot’s involvement. In Mata v. Avianca, Inc., a personal injury lawsuit filed in May 2023, the plaintiff’s attorneys used ChatGPT to generate a legal motion.
