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. 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. 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 March 2025, OpenAI updated ChatGPT to generate images using GPT-4o instead of DALL-E.

• ChatGPT is a chatbot and AI assistant built on large language model (LLM) technology.

One study analyzed ChatGPT’s responses to 517 questions about software engineering or computer programming posed on Stack Overflow for correctness, consistency, comprehensiveness, and concision. ChatGPT has been used to generate introductory sections and abstracts for scientific articles. Andrew Ng argued that «it’s a mistake to fall for the doomsday hype on AI—and that regulators who do will only benefit vested interests.» Yann LeCun dismissed doomsday warnings of AI-powered misinformation and existential threats to the human race. Juergen Schmidhuber said that in 95% of cases, AI research is about making «human lives longer and healthier and easier.» He added that while AI can be used by bad actors, it «can also be used against the bad actors». 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».

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).

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. In The Atlantic magazine’s «Breakthroughs of the Year» for 2022, Derek Thompson included ChatGPT as part of «the generative-AI eruption» that «may change our mind about how we work, how we think, and what human creativity is».

• In September 2025, OpenAI added a feature called Pulse, which generates a daily analysis of a user’s chats and connected apps such as Gmail and Google Calendar.

These labels were used to train a model to detect such content in the future. These rankings were used to create «reward models» that were used to fine-tune the model further by using several iterations of proximal policy optimization. The ethics of its development, particularly the use of copyrighted content as training data, have also drawn controversy. The chatbot can facilitate academic dishonesty, generate misinformation, and create malicious code. As of 2025, ChatGPT’s website is among the top 5 most-visited websites globally, and has over 800 million active weekly users. By January 2023, ChatGPT had become the fastest-growing consumer software application in history, gaining over 100 million users in two months.

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. 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).

GPT-4.5

ChatGPT’s training data only covers a period up to the cut-off date, so it lacks knowledge of recent events. OpenAI acknowledged that there have been «instances where our 4o model fell short in recognizing signs of delusion or emotional dependency», and reported that it is working to improve safety. The user can interrupt tasks or provide additional instructions as needed. In July 2025, OpenAI released ChatGPT agent, an AI agent that can perform multi-step tasks. According to TechCrunch, it is a service based on o3 that combines advanced reasoning and web search capabilities to make comprehensive reports within 5 to vegas casino app 30 minutes. This tool allows a user to customize ChatGPT’s behavior for a specific use case.

GPT Store

In Mata v. Avianca, Inc., a personal injury lawsuit filed in May 2023, the plaintiff’s attorneys used ChatGPT to generate a legal motion. The uses and potential of ChatGPT in health care has been the topic of scientific publications and experts have shared many opinions. Many companies adopted ChatGPT and similar chatbot technologies into their product offers. The dangers are that «meaningless content and writing thereby becomes part of our culture, particularly on social media, which we nonetheless try to understand or fit into our existing cultural horizon.»

ChatGPT

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.

OpenAI collects data from ChatGPT users to further train and fine-tune its services. ChatGPT is based on GPT foundation models that have been fine-tuned for conversational assistance.

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. 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.

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). 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.
