This includes text-to-image models such as Stable Diffusion and large language models such as ChatGPT. In August 2024, the FTC voted unanimously to ban marketers from using fake user reviews created by generative AI chatbots (including ChatGPT) and influencers paying for bots to increase follower counts. ChatGPT has never been publicly available in China because OpenAI prevented Chinese users from accessing their site. Kevin Roose of The New York Times called it “the best artificial intelligence chatbot ever released to the general public”.

In November 2023, OpenAI released GPT Builder a tool for users to customize ChatGPT’s behavior for a specific use case. GPT-based moderation classifiers are used to reduce the risk of harmful outputs being presented to users. ChatGPT is frequently used for translation and summarization tasks, and can simulate interactive environments such as a Linux terminal, a multi-user chat room, or https://www.luckytwicecasino.eu/ simple text-based games such as tic-tac-toe. It is designed to generate human-like text and can carry out a wide variety of tasks.
ChatGPT is programmed to reject prompts that may violate its content policy. In one instance, ChatGPT generated a rap in which women and scientists of color were asserted to be inferior to white male scientists. The reward model of ChatGPT, designed around human oversight, can be over-optimized and thus hinder performance, in an example of an optimization pathology known as Goodhart’s law. OpenAI has sometimes mitigated this effect by updating the training data. The feature is not available for users in the UK, Switzerland, or the European Economic Area, and is available on a waitlist basis everywhere else.
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. 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. It is credited with accelerating the AI boom, an ongoing period marked by rapid investment and public attention toward the field of artificial intelligence (AI). Privacy practices may vary, for example, based on the features you use or your age.
Context window
- In July 2025, OpenAI released ChatGPT agent, an AI agent that can perform multi-step tasks.
- All models were 18 years of age or older at the time of depiction.
- Popular deep learning models are trained on mass amounts of media scraped from the Internet, often utilizing copyrighted material.
- In March 2023, a bug allowed some users to see the titles of other users’ conversations.
- The term “hallucination” as applied to LLMs is distinct from its meaning in psychology, and the phenomenon in chatbots is more similar to confabulation or bullshitting.
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”. As of July 2025, Science expects authors to release in full how AI-generated content is used and made in their work. Popular deep learning models are trained on mass amounts of media scraped from the Internet, often utilizing copyrighted material. 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.
Perplexity – AI Search & Chat
In response, many educators are now exploring ways to thoughtfully integrate generative AI into assessments. Efforts to ban chatbots like ChatGPT in schools focus on preventing cheating, but enforcement faces challenges due to AI detection inaccuracies and widespread accessibility of chatbot technology. The potential benefits include enhancing personalized learning, improving student productivity, assisting with brainstorming, summarization, and supporting language literacy skills. The chatbot technology can improve security by cyber defense automation, threat intelligence, attack identification, and reporting. In an industry survey, cybersecurity professionals argued that it was attributable to cybercriminals’ increased use of generative artificial intelligence (including ChatGPT). Another study, focused on the performance of GPT-3.5 and GPT-4 between March and June 2024, found that performance on objective tasks like identifying prime numbers and generating executable code was highly variable.
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. In September 2025, following the suicide of a 16-year-old, OpenAI said it planned to add restrictions for users under 18, including the blocking of graphic sexual content and the prevention of flirtatious talk. OpenAI CEO Sam Altman said that users were unable to see the contents of the conversations. These images are generated with C2PA metadata, which can be used to verify that they are AI-generated. The model can also generate new images based on existing ones provided in the prompt.
Ratings and reviews
It has an additional feature called “agentic mode” that allows it to take online actions for the user. The laborers were exposed to toxic and traumatic content; one worker described the assignment as “torture”. To build a safety system against harmful content (e.g., sexual abuse, violence, racism, sexism), OpenAI used outsourced Kenyan workers, earning around $1.32 to $2 per hour, to label such content. 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).
Data safety
His experience runs the gamut of media, including print, digital, broadcast, and live events. But when you flip the right switch, the model starts to surprise you. Most people don’t explore that space.
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. Despite this, users may jailbreak ChatGPT with prompt engineering techniques to bypass these restrictions.
These limitations may be revealed when ChatGPT responds to prompts including descriptors of people. ChatGPT’s training data only covers a period up to the cut-off date, so it lacks knowledge of recent events. To implement the feature, OpenAI partnered with data connectivity infrastructure company b.well. On January 7, 2026, OpenAI introduced a feature called “ChatGPT Health”, whereby ChatGPT can discuss the user’s health in a way that is separate from other chats. In 2025, OpenAI added several features to make ChatGPT more agentic (capable of autonomously performing longer tasks).
Their leaders emphasized their earlier caution regarding public deployment was due to the trust the public places in Google Search. Kelsey Piper of Vox wrote that “ChatGPT is the general public’s first hands-on introduction to how powerful modern AI has gotten” and that ChatGPT is “smart enough to be useful despite its flaws”. As before, OpenAI has not disclosed technical details such as the exact number of parameters or the composition of its training dataset.
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. A shadow market has emerged for Chinese users to get access to foreign software tools. 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. 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. ChatGPT gained one million users in five days and 100 million in two months, becoming the fastest-growing internet application in history.
The official app by OpenAI
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”. Geoffrey Hinton, one of the “fathers of AI”, voiced concerns that future AI systems may surpass human intelligence. In July 2023, the US Federal Trade Commission (FTC) issued a civil investigative demand to OpenAI to investigate whether the company’s data security and privacy practices to develop ChatGPT were unfair or harmed consumers. In October 2025, OpenAI banned accounts suspected to be linked to the Chinese government for violating the company’s national security policy. In late March 2023, the Italian data protection authority banned ChatGPT in Italy and opened an investigation.
