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.

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.

Search and retrieval

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. The company then worked with a team of 170 psychiatrists, psychologists, and physicians to prepare responses for users exhibiting mental health emergencies.

• 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.
• A May 2023 statement by hundreds of AI scientists, AI industry leaders, and other public figures demanded that “mitigating the risk of extinction from AI should be a global priority”.
• In an American civil lawsuit, attorneys were sanctioned for filing a legal motion generated by ChatGPT containing fictitious legal decisions.
• 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.

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.

Specialized models

During the same year, industrial buildings made up 2.4% of the total area while housing and buildings made up 8.7% and transportation infrastructure made up 8.3%. As of 2012, a total of 1.35 km2 (0.52 mi2) or 65.5% is used for agricultural purposes, while 0.3 km2 (0.12 mi2) or 14.6% is forested. Beginning in the 1970s the new neighborhoods of Trümlere and Rohrmatt were built for the growing population of commuters.

In August 2024, the FTC voted unanimously to ban marketers from using fake user reviews created by generative AI chatbots non gamstop casinos UK (including ChatGPT) and influencers paying for bots to increase follower counts. ChatGPT has never been publicly available in mainland China, Hong Kong and Macau because OpenAI prevented users from these Chinese regions from accessing their site. A 2023 study reported that GPT-4 obtained a better score than 99% of humans on the Torrance Tests of Creative Thinking. Reinforcement learning consisted of human trainers ranking responses generated by the model in previous conversations. In surveys, respondents favored the release of such a tool by a four-to-one margin, but nearly 30% of users declared that they would use ChatGPT less often if it watermarked outputs and while rival chatbots did not. OpenAI CEO Sam Altman said that users were unable to see the contents of the conversations.
