Investors are waiting too, dumping unfathomable amounts of capital into AI companies, data centers, and the physical infrastructure that they believe is necessary to bring about this arrival. But their ability to mimic us—in part due to the human feedback in their training—has inspired scientists and researchers to ask questions about our cognition and further probe how our minds work. People use them to generate entire songs; at least one debuted on a Billboard chart. Generative-AI tools are used to write personalized bedtime stories and digitally reanimate children killed in mass shootings.
GPT-4o
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.
Model versions
Computer users can only access ChatGPT through their browser unless OpenAI completes its development of native desktop applications for multiple operating systems. Through official mobile apps for both the iOS and Android operating systems, users can easily access ChatGPT from any location. The paid version is appropriate for users who require continuous access to advanced AI benefits, while the free version is suitable for users who require basic general usage. With its many features, this multipurpose AI assistant is an essential tool for users at work and at home.
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. In December 2024, OpenAI launched a new feature allowing users to call ChatGPT with a telephone for up to 15 minutes per month for free. 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 simple text-based games such as tic-tac-toe.

Despite decades of using AI, Wall Street professionals report that consistently beating the market with AI, including recent large language models, is challenging due to limited and noisy financial data. The FTC asked OpenAI for comprehensive information about its technology and privacy safeguards, as well as any steps taken to prevent the recurrence of situations in which its chatbot generated false and derogatory content about people. Over many iterations of ChatGPT, plus users maintained more access to better models than the free tier provided, and access to additional features like voice mode.
Features
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. 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 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.
- Robin Bauwens, an assistant professor at Tilburg University, found that a ChatGPT-generated peer review report on his article mentioned nonexistent studies.
- Depending on a person’s view, one might see these models as a useful tool; others as “stochastic parrots” or fancy autocorrect; and others still as catalysts for a fearsome alien intelligence.
- AI powers ChatGPT as the system enhances its knowledge through every interaction to become more user-friendly with time.
- 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.
Depending on a person’s view, one might see these models as a useful tool; others as “stochastic parrots” or fancy autocorrect; and others still as catalysts for a fearsome alien intelligence. Artists of all kinds protested as large language models, trained on the creative output of humankind, threatened to render their jobs irrelevant or obsolete—or to simply devalue creative work altogether. OpenAI’s product solidified the oracular chatbot as the primary way the world interacts with large language models. The ability of ChatGPT to modify its responses based on user input enables it to create tailored interactions, which produce a more fun engagement than standard chatbots. Multiple generations of AI software development have led the technology to generate more precise and helpful responses that sound naturally human.
(OpenAI denies responsibility for this incident.) People fell in love with the tools and gave them names. People confided in the chatbots as they would therapists. More people started using phrases such as p(doom) and situational awareness. (OpenAI entered into a corporate partnership with The Atlantic last year.) Some businesses laid off staff as chatbots became more useful.
The integration used ChatGPT to write prompts for DALL-E guided by conversations with users. GPT-4, which was released on March 14, 2023, was made available via API and for premium ChatGPT users. The Pro launch coincided with the release of the o1 model, providing unlimited access to o1 and advanced voice mode.
It allows ChatGPT to search the web in an attempt to make more accurate and up-to-date responses. To prevent offensive outputs from being presented to and produced by ChatGPT, queries are filtered through the OpenAI "Moderation endpoint" API (a separate GPT-based AI). 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. Users can upvote or downvote responses they receive from ChatGPT and fill in a text field with additional feedback. 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 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. 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. In October 2025, OpenAI reported that approximately 0.15% of ChatGPT's active users in a given week have conversations including explicit indicators of potential suicidal planning or intent, translating to more than a million people weekly. ChatGPT is a chatbot and AI assistant built on large language model (LLM) technology. In the reinforcement learning stage, human trainers first ranked responses generated by the model in previous conversations.
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." This has led to concern over the rise of what has come to be called "synthetic media" and "AI slop" which are generated by AI and rapidly spread over social media and the internet. The Guardian questioned whether any content found on the Internet after ChatGPT's release "can be truly trusted" and called for government regulation.

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.
The user can interrupt tasks or provide additional instructions as needed. 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 30 minutes. ChatGPT's Mandarin Chinese abilities were lauded, but the ability of the AI to produce winaura content in Mandarin Chinese in a Taiwanese accent was found to be "less than ideal" due to differences between mainland Mandarin Chinese and Taiwanese Mandarin.
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 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.
Google Gemini stands out because of its seamless connection to Google's extensive database, thus acting as a robust information research and verification system. Users can acquire real-time solutions together with content support from Gemini while receiving conversational advice like ChatGPT. The highly popular AI-driven conversational tool ChatGPT shares its features with alternative tools, which present comparable capabilities. Users can access ChatGPT through several platforms, which ensures compatibility with various devices. AI powers ChatGPT as the system enhances its knowledge through every interaction to become more user-friendly with time. Users can use this technology to schedule events and remember obligations, and prompt their thought organization with structured guidance.
