ChatGPT Wikipedia

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. ChatGPT and other chatbots have a tendency to flatter and agree with users even when they are wrong, sometimes to the point of validating delusions. The training data of large language models only covers a period up to the cut-off date, so ChatGPT lacks knowledge of recent events, but it can search the web for up-to-date information. Originally released on November 30, 2022, the product uses large language models—specifically generative pre-trained transformers (GPTs)—to generate text, speech, and images in response to user prompts. As of  2000update, there were a total of 87 students attending any school in the municipality. In 2008update there were a total of 130 full-time equivalent jobs.

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.

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”.

Regional responses

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.

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.

• In November 2023, OpenAI released GPT Builder, a tool allowing users to customize ChatGPT’s behavior for a specific use case.
• 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.
• 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.

ChatGPT Health

OpenAI allows businesses to tailor how their content appears in the ChatGPT Search results and influence what sources are used. 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. The chatbot can facilitate academic dishonesty, generate misinformation, and create malicious code.

What ChatGPT Work can do

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.

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 non gamstop casino 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.

It was capable of autonomously performing tasks through web browser interactions, including filling forms, placing online orders, scheduling appointments, and other browser-based tasks. The model can also generate new images based on existing ones provided in the prompt. One of the most significant improvements was in the generation of text within images, which is especially useful for branded content.
