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 March 2025, OpenAI updated ChatGPT to generate images using GPT-4o instead of DALL-E.
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). It doesn’t matter that the technology is already useful to many, that it can code and write marketing copy and complete basic research tasks. Like ChatGPT before its release, every model in some way is also a “low-key research preview”—a proof of concept for what’s really possible. We are waiting because a defining feature of generative AI, according to its true believers, is that it is never in its final form.
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". Like GPT-5, it comes with a "Thinking" mode for complex problem-solving and an "Instant" mode for fast responses. As before, OpenAI has not disclosed technical details such as the exact number of parameters or the composition of its training dataset. According to OpenAI, it features reduced hallucinations and enhanced pattern recognition, creativity, and user interaction.
The premium subscription from OpenAI, named ChatGPT Plus, lets users access faster responses and get priority access during peak usage times, along with the latest improved AI models. In the 2020s, the rapid advancement of deep learning-based generative artificial intelligence models raised questions about the copyright status of AI-generated works, and about whether copyright infringement occurs when such are trained or used. If the disappointing-technology hype cycles that preceded large language models—cryptocurrency booms and busts, Web3 and the metaverse—felt like solutions in search of a problem, generative AI seemed to offer limitless applications. Moreover, OpenAI has introduced ChatGPT Atlas, a browser-integrated tool that allows users to access web-based information in real time. ChatGPT is an advanced conversational AI (or chatbot) developed by OpenAI, designed to engage users in natural language dialogue and provide informative responses across a wide range of topics.
Stanford researchers reported that GPT-4 "passes a rigorous Turing test, diverging from average human behavior chiefly to be more cooperative." 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.
This feature greatly enhances the AI’s usefulness for research, learning, and content creation. ChatGPT can overcome the drawback of being trained solely on pre-existing data by using Atlas to retrieve current knowledge and verify facts online. While ChatGPT specializes in text, OpenAI has developed other tools that expand creative possibilities. 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. The attorneys were sanctioned for filing the motion and presenting the fictitious legal decisions ChatGPT generated as authentic.
The models got better, and the unintended consequences grew commensurately. ChatGPT introduced millions to a tool that, although prone to presenting false information, simulates conversation well enough that people began to use it as an interface for countless tasks, such as finding information. Today, it has 800 million weekly users. The system delivers sourced material for users looking to verify their research findings, making it an excellent selection regarding academic reference needs. Online accessibility of this tool eliminates the dependency on powerful hardware devices because it operates through the cloud.
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. This includes text-to-image models such as Stable Diffusion and large language models such as ChatGPT. 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. Kevin Roose of The New York Times called it "the best artificial intelligence chatbot ever released to the general public".
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. In 2023, OpenAI worked with a team of 40 Icelandic volunteers to fine-tune ChatGPT's Icelandic conversation skills as a part of Iceland's attempts to preserve the Icelandic language. TrendForce market intelligence estimated that 30,000 Nvidia GPUs (each costing approximately $10,000–15,000) were used to power ChatGPT in 2023. In October 2023, OpenAI's image generation model DALL-E 3 was integrated into ChatGPT Plus and ChatGPT Enterprise. 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.
ChatGPT can find more up-to-date information by searching the web, but this doesn't ensure that responses are accurate, as it may access unreliable or misleading websites. A 2025 Sentio University survey of 499 LLM users with self-reported mental health conditions found that 96.2% use ChatGPT, with 48.7% using it specifically for mental health support or therapy-related purposes. 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. This tool allows a user to customize ChatGPT's behavior for a specific use case.
In June 2023, hundreds of people attended a "ChatGPT-powered church service" at St. Paul's Church in Fürth, Germany. Between March and April 2023, Il Foglio published one ChatGPT-generated article a day on its website, hosting a special contest for its readers in the process. In December 2022, the question-and-answer website Stack Overflow banned the use of ChatGPT for generating answers to questions, citing the factually ambiguous nature of its responses.
The system deviates from primitive rule-based bots since ChatGPT absorbs huge data inputs and enhances itself through feedback from users. 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. 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". 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. A shadow market has emerged for users to get access to foreign software tools. ChatGPT has never been publicly available in China because OpenAI prevented Chinese users from accessing their site.
It is designed to generate human-like text and can carry out a wide variety of tasks. ChatGPT's training data includes software manual pages, information about internet phenomena such as bulletin board systems, multiple programming languages, and the text of Wikipedia. OpenAI's outsourcing partner was Sama, a training-data company based in San Francisco, California.
Despite its intriguing AI-based features, Sora is presently inaccessible through ChatGPT, underscoring the wide range of AI tools available. Through OpenAI platform development, OpenAI has built ChatGPT as an advanced conversational AI able to generate natural human language from received inputs. 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". 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).
As of July 2025, Science expects authors to release in full how AI-generated content is used and made in their work. 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". 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. 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.
The models do not have souls or rights. But for plenty of people, their first encounter with ChatGPT checked many of the boxes of a winaura transformative technology. These tools are not magic, nor are they “intelligent” in any human way.
