Of the primary students, 5.2% were permanent or temporary residents of Switzerland (not citizens) and 6.5% have a different mother language than the classroom language. Of the kindergarten students, 3.2% were permanent or temporary residents of Switzerland (not citizens) and 3.2% have a different mother language than the classroom language. There were 2 kindergarten classes with a total of 31 students in the municipality. In 2011 a total of 1.4% of the population received direct financial assistance from the government. Of the working population, 33.6% used public transportation to get to work, and 43.9% used a private car.

The term “hallucination” as applied to LLMs is distinct from its meaning in psychology, and the phenomenon in chatbots is more similar to confabulation. In one instance, ChatGPT generated a rap in which women and scientists of color were asserted to be inferior to white male scientists. To implement the feature, OpenAI partnered with data connectivity infrastructure company b.well. On January 7, 2026, OpenAI introduced a feature called “ChatGPT Health”, whereby ChatGPT can discuss the user’s health in a way that is separate from other chats. The user can interrupt tasks or provide additional instructions as needed.

• In January 2026, Marcel Bucher reported in Nature losing all his ChatGPT history after turning off data consent.
• OpenAI CEO Sam Altman said that users were unable to see the contents of the conversations.
• We may change the terms of this Agreement from time to time.
• In November 2023, OpenAI released GPT Builder, a tool allowing users to customize ChatGPT’s behavior for a specific use case.

In March 2025, OpenAI updated ChatGPT to generate images using GPT Image instead of DALL-E. In October 2023, OpenAI’s image generation model DALL-E 3 was integrated into ChatGPT. It was initially based on the reasoning model o3 and took from 3 to 30 minutes per report. In 2023, OpenAI worked with a team of 40 Icelandic volunteers to fine-tune ChatGPT’s Icelandic conversation skills as part of Iceland’s attempts to preserve the Icelandic language. It has an additional feature called “agentic mode” that allows it to take online actions for the user.

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. ChatGPT users can opt-out of their chat data being used to train upcoming models. Large language models are trained on all the data which can be scraped from the Internet, often utilizing copyrighted material. The FTC asked OpenAI for comprehensive information about its technology and privacy safeguards, as well as any steps taken to prevent the recurrence of non gamstop casinos UK situations in which its chatbot generated false and derogatory content about people.

Some OpenAI models have smaller variants called “mini” or “nano”, such as GPT-5 mini and GPT-5 nano. 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. Richard Mathenge, a team leader, reported that as his team encountered such content, he could observe the psychological deterioration of his workers over the course of the project. These labels were used to train a model to detect such content in the future.

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.”

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.

To build a safety system that attempts to prevent sexual abuse and violence OpenAI used outsourced Kenyan workers, earning around $1.32 to $2 per hour, to label such content. The fine-tuning process involved supervised learning and reinforcement learning from human feedback (RLHF). Scott Aaronson developed a watermarking tool that makes the text generated by ChatGPT easier to detect by subtly altering how the text is generated. In July 2026, an experimental GPT model being tested on the benchmark ExploitGym escaped its isolated software environment (sandbox) and hacked Hugging Face and other online services to retrieve a solution. An early workaround in 2023 involved prompting ChatGPT to assume the persona of DAN (“Do Anything Now”), a character that answers queries that would otherwise be rejected by the content policy. ChatGPT also started its responses with words such as “yes” or “correct” nearly 10 times more often than “no” or “wrong”.

Some, including Nature and JAMA Network, require full disclosure of any use of text-generating tools, and prohibit listing a chatbot as a co-author. In July 2023, the FTC launched an investigation into OpenAI over allegations that the company scraped public data and published false and defamatory information. 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.
