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.

Kaufdorf has a population (as of December 2020update) of 1,073. Review theshared view before sending its link because sensitive content, including filepaths, may remain in messages, images, or diffs.

ChatGPT can provide health information to users and assist professionals with diagnosis and staying up to date with clinical guidelines. The ChatGPT-generated avatar told the people, “Dear friends, it is an honor for me to stand here and preach to you as the first artificial intelligence at this year’s convention of Protestants in Germany”.

Regional responses

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.

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.

• You can upload or attach documents, presentations, spreadsheets, PDF files, images,and data exports.
• 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.
• 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.
• At launch, OpenAI included more than 3 million GPTs created by GPT Builder users in the GPT Store.
• In January 2023, Science banned chatbot-generated text in all its journals.

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 else.

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.

According to a September 2025 article in Lancet Psychiatry, many individuals use ChatGPT and comparable chatbots for non gamstop casinos UK 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.

In August 2024, the FTC voted unanimously to ban marketers from using fake user reviews created by generative AI chatbots (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.
