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. It is capable of writing software, answering codebase questions, running tests, and proposing pull requests. 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.

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. 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. 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.
Age restrictions
- 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 July 2025, OpenAI released ChatGPT agent, an AI agent that can perform multi-step tasks.
- 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.
- The company announced a slew of generative AI-powered features to counter OpenAI and Microsoft.
- In March 2023, a bug allowed some users to see the titles of other users’ conversations.
- These limitations may be revealed when ChatGPT responds to prompts including descriptors of people.
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. 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. 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. It is designed to generate human-like text and can carry out a wide variety of tasks. ChatGPT is a chatbot and AI assistant built on large luck of spins casino review language model (LLM) technology. OpenAI's outsourcing partner was Sama, a training-data company based in San Francisco, California.
Regional responses
A study presented example attacks on ChatGPT, including jailbreaks and reverse psychology. ChatGPT is programmed to reject prompts that may violate its content policy. 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. These limitations may be revealed when ChatGPT responds to prompts including descriptors of people. OpenAI has sometimes mitigated this effect by updating the training data. ChatGPT's training data only covers a period up to the cut-off date, so it lacks knowledge of recent events.
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". Samantha Lock of The Guardian noted that it was able to generate "impressively detailed" and "human-like" text.
- In the case of supervised learning, the trainers acted as both the user and the AI assistant.
- 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.
- ChatGPT has never been publicly available in China because OpenAI prevented Chinese users from accessing their site.
- In a nutshell, ChatGPT uses AI and machine learning to understand and respond to user’s prompts.
- The chatbot can facilitate academic dishonesty, generate misinformation, and create malicious code.
- A study presented example attacks on ChatGPT, including jailbreaks and reverse psychology.
- It allows ChatGPT to search the web in an attempt to make more accurate and up-to-date responses.
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. As of July 2025, Science expects authors to release in full how AI-generated content is used and made in their work. 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. 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.
Astell&Kern ends 2025 with even more flagship product launches
A shadow market has emerged for chinese users to get access to foreign software tools. Kevin Roose of The New York Times called it "the best artificial intelligence chatbot ever released to the general public". GPT-5 was launched on August 7, 2025, and is publicly accessible through ChatGPT, Microsoft Copilot, and via OpenAI's API. OpenAI CEO Sam Altman said that users were unable to see the contents of the conversations.
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. 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. In the reinforcement learning stage, human trainers first ranked responses generated by the model in previous conversations. 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.
It sounds complicated (and that’s because it is) and especially time consuming, but the reality is that ChatGPT can generate an answer in a matter of seconds. From here, it will then try and comprehend each token to build its response, based on what it’s learned from its training. In a nutshell, ChatGPT uses AI and machine learning to understand and respond to user’s prompts. We explain everything you need to know about the AI-powered tool ChatGPT here, including how it works, whether it’s free to use and how you can use the tool yourself.
Users can simply type a question or task (also known as “prompts”) into ChatGPT and it will generate relevant, conversational text responses. The attorneys were sanctioned for filing the motion and presenting the fictitious legal decisions ChatGPT generated as authentic. 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.
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 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. 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).
