ChatGPT Wikipedia

Geoffrey Hinton, one of the «fathers of AI», voiced concerns that future AI systems may surpass human intelligence. In July 2023, the US Federal Trade Commission (FTC) issued a civil investigative demand to OpenAI to investigate whether the company’s data security and privacy practices to develop ChatGPT were unfair or harmed consumers. In June 2025, OpenAI reported increased use of ChatGPT for China-origin influence operations. In late March 2023, the Italian data protection authority banned ChatGPT in Italy and opened an investigation. Their leaders emphasized their earlier caution regarding public deployment was due to the trust the public places in Google Search. It is the most popular AI chatbot as of August 2026, with an estimated 79% of the market share according to StatCounter.

• Another study, focused on the performance of GPT-3.5 and GPT-4 between March and June 2024, found that performance on objective tasks like identifying prime numbers and generating executable code was highly variable.
• As of 2008update, the population was 49.7% male and 50.3% female.
• There were 2 kindergarten classes with a total of 31 students in the municipality.
• In January 2023, Science banned chatbot-generated text in all its journals.
• The study notes a lack of research on efficacy, poor consistency in dangerous situations, limited regulation and liability, and poor transparency from OpenAI.

Model versions

According to a September 2025 article in Lancet Psychiatry, many individuals use ChatGPT and comparable chatbots for mental health and emotional support despite a warning from OpenAI against using ChatGPT as a therapist. According to a 2024 study in the International Journal of Surgery, concerns include «research fraud, lack of originality, ethics, copyright, legal difficulties». However, 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.

Keep related chats, files, and instructions in one projectwhen the work will continue over time or depend on the same context. In the UK, a judge expressed concern about self-representing litigants wasting time by submitting documents containing significant hallucinations. In an American civil lawsuit, attorneys were sanctioned for filing a legal motion generated by ChatGPT containing fictitious legal decisions. The study notes a lack of research on efficacy, poor consistency in dangerous situations, limited regulation and liability, and poor transparency from OpenAI.

A February 2023 study in PLOS Digital Health found that ChatGPT 3.5 was capable of passing the United States Medical Licensing Examination. In medical education, it can explain concepts, generate case scenarios, and be used by students preparing for licensing examinations. Many companies adopted ChatGPT and similar chatbot technologies into their product offers. The Guardian questioned whether any content found on the Internet after ChatGPT’s release «can be truly trusted» and called for government regulation. 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.

Students have generally reported positive perceptions, but specific views from educators and students vary widely. When compared to similar chatbots at the time, the GPT-4 version of ChatGPT was the most accurate at coding. As of July 2025, Science expects authors to release in full how AI-generated content is used and made in their work. In January 2023, Science banned chatbot-generated text in all its journals.

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. During supervised learning, the trainers acted as both the user and the AI assistant, providing examples of how the chatbot is expected to respond. ChatGPT is based on GPT foundation models that have been fine-tuned for conversational assistance. In January 2026, Marcel Bucher reported in Nature losing all his ChatGPT history after turning off data consent.

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». 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. Once a user reaches usage limits, ChatGPT may transition to the «mini» version. Mophat Okinyi, a quality-assurance analyst on the same team, reported lasting insomnia, anxiety, depression, and panic attacks, and said the experience contributed to the breakdown of his marriage and mental health.

Of these, there were 30 people employed in the primary economic sector and about 12 businesses involved in this sector. In the federal election, a total of 472 votes were cast, and the voter turnout was 63.9%. In 2011, single family homes made up 68.2% of the total housing in the municipality. Of the population in the municipality, 179 or about 22.7% were born in Kaufdorf and lived there in 2000. The population was made up of 458 Swiss men (44.5% of the population) and 53 (5.2%) non-Swiss men.

These limitations may be revealed when ChatGPT responds to prompts including descriptors of people. 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. On 17 January 2026, OpenAI announced that it would start testing advertisements in its free version for logged-in, adult US users. The feature is not available for users in the United Kingdom, Switzerland, or the European Economic Area (EEA), and is available on a waitlist basis everywhere non gamstop casino else.

A shadow market has emerged for mainland Chinese users to get access to foreign software tools. 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. Stanford researchers reported that GPT-4 «passes a rigorous Turing test, diverging from average human behavior chiefly to be more cooperative.»
