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 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.
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). These issues have led to its use being restricted in some workplaces and educational institutions and have prompted widespread calls for the regulation of artificial intelligence.
Various applications with note-taking software, as well as customer service platforms and workflow automation tools, now utilize AI similar to ChatGPT to enhance their operational efficiency. Creative workers who seek script development or poetry creation assistance, together with storytelling improvement, utilize ChatGPT as a valuable tool. The system supports authors in multiple stages of writing, including draft improvement and thought development, and prevents writer's block as well. The main reason behind obtaining ChatGPT stems from its immediate capability to return structured responses about many kinds of questions. For those who wish to enhance their creative workflow and have access to their own conversational AI assistant around-the-clock, ChatGPT is a game-changer.
AI Chatbot – Nova
The advanced nature of this AI-powered language model makes it stand at the top of available sophisticated systems. Deep learning plus natural language processing create this system, which processes context while reshaping its responses to maintain meaningful conversation flow. The system serves as a virtual assistant, automated chatbot, and AI writing software that provides information answers, assists with content creation, summaries, and code solutions. ChatGPT shows inconsistent responses, lack of specificity, lack of control over patient data, and a limited ability to take additional context (such as regional variations) into consideration. In July 2024, Futurism reported that GPT-4o in ChatGPT would sometimes link "scam news sites that deluge the user with fake software updates and virus warnings"; these pop-ups can be used to coerce users into downloading malware or potentially unwanted programs. Chris Granatino, a librarian at Seattle University, noted that while ChatGPT can generate content that seemingly includes legitimate citations, in most cases those citations are not real or largely incorrect.
GPT-4o
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.
- 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”.

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.
Released in February 2025, GPT-4.5 was described by Altman as a "giant, expensive model". In September 2024, OpenAI introduced o1-preview and a faster, cheaper model named o1-mini. GPT-4o ("o" for "omni") is a multilingual, multimodal generative pre-trained transformer developed by OpenAI and released in May 2024. ChatGPT does not attempt to verify these attestations and does not have any age restrictions built in to its technology. A study presented example attacks on ChatGPT, including jailbreaks and reverse psychology. ChatGPT is programmed to reject prompts that may violate its content policy.
- Google Gemini stands out because of its seamless connection to Google’s extensive database, thus acting as a robust information research and verification system.
- These include, among many others, writing and debugging computer programs, composing music, scripts, fairy tales, and essays, answering questions (sometimes at a level exceeding that of an average human test-taker), and generating business concepts.
- The best way to use Microsoft Copilot is as an integrated tool that supports the Microsoft Word, Excel, and Outlook platforms.
- The languages tested were Polish, French, Korean, Spanish, Arabic, Tagalog, and Amharic.
- 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.
- But for plenty of people, their first encounter with ChatGPT checked many of the boxes of a transformative technology.

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.

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 winaura responses.
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.
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.
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".
Samantha Lock of The Guardian noted that it was able to generate "impressively detailed" and "human-like" text. GPT-5 was launched on August 7, 2025, and is publicly accessible through ChatGPT, Microsoft Copilot, and via OpenAI's API. 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.
It can generate plausible-sounding but incorrect or nonsensical answers known as hallucinations. Despite its acclaim, the chatbot has been criticized for its limitations and potential for unethical use. At the same time, its release prompted extensive media coverage and public debate about the nature of creativity and the future of knowledge work. It has been lauded as a revolutionary tool that could transform numerous professional fields.
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.

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. In one instance, ChatGPT generated a rap in which women and scientists of color were asserted to be inferior to white male scientists. 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.
