OpenAI’s outsourcing partner was Sama, a training-data company based in San Francisco, California. These labels were used to train a model to detect such content in the future. The ethics of its development, particularly the use of copyrighted content as training data, have also drawn controversy. The chatbot can facilitate academic dishonesty, generate misinformation, and create malicious code. The service gained 100 million users in two months, making it the fastest-growing consumer software application in history.
In the UK, a judge expressed concern about self-representing litigants wasting time by submitting documents containing significant hallucinations. In November 2025, OpenAI acknowledged that there have been “instances where our 4o model fell short in recognizing signs of delusion or emotional dependency”, and reported that it is working to improve safety. In medical education, it can explain concepts, generate case scenarios, and be used by students preparing for licensing examinations. 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.
This includes text-to-image models such as Stable Diffusion and large language models such as ChatGPT. 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 China because OpenAI prevented Chinese users from accessing their site. Kevin Roose of The New York Times called it “the best artificial intelligence chatbot ever released to the general public”.

• A 2023 analysis estimated that ChatGPT hallucinates around 3% of the time.

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.

Quick Tips for ChatGPT

Generative Pre-trained Transformer 4 (GPT-4) is a large language model developed by OpenAI and the fourth in its series of GPT foundation models. 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. OpenAI CEO Sam Altman said that users were unable to see the contents of the conversations. These images are generated with C2PA metadata, which can be used to verify that they are AI-generated. The model can also generate new images based on existing ones provided in the prompt.

GPT-5 was launched on August 7, 2025, and is publicly accessible through ChatGPT, Microsoft Copilot, and via OpenAI’s API. According to OpenAI, it was intended to reduce hallucinations and enhance pattern recognition, creativity, and user interaction. Released in February 2025, GPT-4.5 was described by Altman as a “giant, expensive model”.

• 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 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”.
• Samantha Lock of The Guardian noted that it was able to generate “impressively detailed” and “human-like” text.
• The chatbot can facilitate academic dishonesty, generate misinformation, and create malicious code.
• GPT-4o (“o” for “omni”) is a multilingual, multimodal generative pre-trained transformer developed by OpenAI and released in May 2024.
• The model’s baseline tone is practical, but a perspective shift convinces it to behave like a storyteller instead of a rulebook.

It has an additional feature called “agentic mode” that allows it to take online actions for the user. The laborers were exposed to toxic https://www.luckytwicecasino.eu/ and traumatic content; one worker described the assignment as “torture”. To build a safety system against harmful content (e.g., sexual abuse, violence, racism, sexism), OpenAI used outsourced Kenyan workers, earning around $1.32 to $2 per hour, to label such content. In the case of supervised learning, the trainers acted as both the user and the AI assistant. The fine-tuning process involved supervised learning and reinforcement learning from human feedback (RLHF).

In response, many educators are now exploring ways to thoughtfully integrate generative AI into assessments. Efforts to ban chatbots like ChatGPT in schools focus on preventing cheating, but enforcement faces challenges due to AI detection inaccuracies and widespread accessibility of chatbot technology. The potential benefits include enhancing personalized learning, improving student productivity, assisting with brainstorming, summarization, and supporting language literacy skills. The chatbot technology can improve security by cyber defense automation, threat intelligence, attack identification, and reporting. In an industry survey, cybersecurity professionals argued that it was attributable to cybercriminals’ increased use of generative artificial intelligence (including ChatGPT). 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.

Ratings and reviews

All models were 18 years of age or older at the time of depiction. In an American civil lawsuit, attorneys were sanctioned for filing a legal motion generated by ChatGPT containing fictitious legal decisions. This has led to concern over the rise of AI slop whereby “meaningless content and writing thereby becomes part of our culture, particularly on social media, which we nonetheless try to understand or fit into our existing cultural horizon.” 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. When compared to similar chatbots at the time, the GPT-4 version of ChatGPT was the most accurate at coding.

ChatGPT is a chatbot and AI assistant built on large language model (LLM) technology. OpenAI collects data from ChatGPT users to further train and fine-tune its services. 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. ChatGPT is based on GPT foundation models that have been fine-tuned for conversational assistance. It uses generative pre-trained transformers (GPTs), such as GPT-5, to generate text, speech, and images in response to user prompts.
In September 2025, OpenAI added a feature called Pulse, which generates a daily analysis of a user’s chats and connected apps such as Gmail and Google Calendar. In December 2024, OpenAI launched a new feature allowing users to call ChatGPT with a telephone for up to 15 minutes per month for free. An optional “Memory” feature allows users to tell ChatGPT to memorize specific information. 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.

One of the most significant improvements was in the generation of text within images, which is especially useful for branded content. 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.
Several studies have shown that ChatGPT can outperform Google Translate in some mainstream translation tasks. ChatGPT (based on GPT-4) was better able to translate Japanese to English when compared to Bing, Bard, and DeepL Translator in 2023. In 2023, OpenAI worked with a team of 40 Icelandic volunteers to fine-tune ChatGPT’s Icelandic conversation skills as a part of Iceland’s attempts to preserve the Icelandic language. According to the company, Plus provided access during peak periods, no downtime, priority access to new features, and faster response speeds. ChatGPT was initially free to the public and remains free in a limited capacity.
For the last five years, he served as head writer for Voicebot.ai and was on the leading edge of reporting on generative AI and large language models. 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. In January 2023, the International Conference on Machine Learning banned any undocumented use of ChatGPT or other large language models to generate any text in submitted papers.
