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”. As before, OpenAI has not disclosed technical details such as the exact number of parameters or the composition of its training dataset.
- In medical education, it can explain concepts, generate case scenarios, and be used by students preparing for licensing examinations.
- The chatbot can assist patients seeking clarification about their health.
- 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.
- The fine-tuning process involved supervised learning and reinforcement learning from human feedback (RLHF).
- 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”.
All models were 18 years of age or older at the time of depiction. In an American civil lawsuit, attorneys were sanctioned for filing a legal motion generated by ChatGPT containing fictitious legal decisions. This has led to concern over the rise of AI slop whereby “meaningless content and writing thereby https://www.luckytwicecasino.eu/ becomes part of our culture, particularly on social media, which we nonetheless try to understand or fit into our existing cultural horizon.” 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. When compared to similar chatbots at the time, the GPT-4 version of ChatGPT was the most accurate at coding.
Age restrictions
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 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. However, no machine translation services match human expert performance.

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. Despite this, users may jailbreak ChatGPT with prompt engineering techniques to bypass these restrictions.
It can generate plausible-sounding but incorrect or nonsensical answers, known as hallucinations. The chatbot has also been criticized for its limitations and potential for unethical use. It has been lauded for its potential to transform numerous professional fields, and instigated public debate about the nature of creativity and the future of knowledge work. 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). Privacy practices may vary, for example, based on the features you use or your age.

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. 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. OpenAI CEO Sam Altman said that users were unable to see the contents of the conversations. These images are generated with C2PA metadata, which can be used to verify that they are AI-generated. The model can also generate new images based on existing ones provided in the prompt.
- In July 2023, the FTC launched an investigation into OpenAI over allegations that the company scraped public data and published false and defamatory information.
- 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.
- The content available may include pornographic material.
- The chatbot technology can improve security by cyber defense automation, threat intelligence, attack identification, and reporting.
- The chatbot has also been criticized for its limitations and potential for unethical use.
- 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.
In November 2023, OpenAI released GPT Builder a tool for users to customize ChatGPT’s behavior for a specific use case. GPT-based moderation classifiers are used to reduce the risk of harmful outputs being presented to users. 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. It is designed to generate human-like text and can carry out a wide variety of tasks.
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. An optional “Memory” feature allows users to tell ChatGPT to memorize specific information. 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.
Gmail – Email by Google
O1 is designed to solve more complex problems by spending more time “thinking” before it answers, enabling it to analyze its answers and explore different strategies. In September 2024, OpenAI introduced o1-preview and a faster, cheaper model named o1-mini. On July 18, 2024, OpenAI released GPT-4o mini, a smaller version of GPT-4o which replaced GPT-3.5 Turbo on the ChatGPT interface. OpenAI has not revealed technical details and statistics about GPT-4, such as the precise size of the model. 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. A 2023 analysis estimated that ChatGPT hallucinates around 3% of the time.
GPT-5 was launched on August 7, 2025, and is publicly accessible through ChatGPT, Microsoft Copilot, and via OpenAI’s API. According to OpenAI, it was intended to reduce hallucinations and enhance pattern recognition, creativity, and user interaction. Released in February 2025, GPT-4.5 was described by Altman as a “giant, expensive model”.
Regional responses
In the UK, a judge expressed concern about self-representing litigants wasting time by submitting documents containing significant hallucinations. In November 2025, 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. In medical education, it can explain concepts, generate case scenarios, and be used by students preparing for licensing examinations. 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.
