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.
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. GPT-4o’s ability to generate images was released later, in March 2025, when it replaced DALL-E 3 in ChatGPT. GPT-4o (« o » for « omni ») is a multilingual, multimodal generative pre-trained transformer developed by OpenAI and released in May 2024. As of 2026update, if the user turns off data sharing for privacy, all previous transcripts and projects are permanently deleted without warning.

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.
His experience runs the gamut of media, including print, digital, broadcast, and live events. But when you flip the right switch, the model starts to surprise you. Most people don’t explore that space.

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. A shadow market has emerged for 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. In December 2023, ChatGPT became the first non-human to be included in Nature’s 10, an annual listicle curated by Nature of people considered to have made significant impact in science. ChatGPT gained one million users in five days and 100 million in two months, becoming the fastest-growing internet application in history.
ChatGPT is programmed to reject prompts that may violate its content policy. In one instance, ChatGPT generated a rap in which women and scientists of color were asserted to be inferior to white male scientists. 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. OpenAI has sometimes mitigated this effect by updating the training data. The feature is not available for users in the UK, Switzerland, or the European Economic Area, and is available on a waitlist basis everywhere else.

According to TechCrunch, it is a service based on o3 that combines advanced reasoning and web search capabilities to make comprehensive reports within 5 to 30 minutes. ChatGPT’s Mandarin Chinese abilities were lauded, but the ability of the AI to produce content in Mandarin Chinese in a Taiwanese accent was found to be « less than ideal » due to differences between mainland Mandarin Chinese and Taiwanese Mandarin. However, no machine translation services match human expert performance.
Version History
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.
Let ChatGPT Handle Your Online Busywork
- I want a hot take that sounds like it would start a family argument.” The trick here is to acknowledge what the model typically gives you and frame the request as a deviation.
- According to TechCrunch, it is a service based on o3 that combines advanced reasoning and web search capabilities to make comprehensive reports within 5 to 30 minutes.
- Many companies adopted ChatGPT and similar chatbot technologies into their product offers.
- In January 2023, Science « completely banned » LLM-generated text in all its journals; however, this policy was just to give the community time to decide what acceptable use looks like.
- 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.
- It has been lauded for its potential to transform numerous professional fields, and instigated public debate about the nature of creativity and the future of knowledge work.
Chris Granatino, a librarian at Seattle University, noted that while ChatGPT can generate content that seemingly includes legitimate citations, in most https://www.luckytwicecasino.eu/ cases those citations are not real or largely incorrect. Robin Bauwens, an assistant professor at Tilburg University, found that a ChatGPT-generated peer review report on his article mentioned nonexistent studies. Some, including Nature and JAMA Network, « require that authors disclose the use of text-generating tools and ban listing a large language model (LLM) such as ChatGPT as a co-author ». Over 20,000 signatories including Yoshua Bengio, Elon Musk, and Apple co-founder Steve Wozniak, signed a March 2023 open letter calling for an immediate pause of giant AI experiments like ChatGPT, citing « profound risks to society and humanity ». In July 2023, the FTC launched an investigation into OpenAI over allegations that the company scraped public data and published false and defamatory information.
O1 is designed to solve more complex problems by spending more time « thinking » before it answers, enabling it to analyze its answers and explore different strategies. In September 2024, OpenAI introduced o1-preview and a faster, cheaper model named o1-mini. On July 18, 2024, OpenAI released GPT-4o mini, a smaller version of GPT-4o which replaced GPT-3.5 Turbo on the ChatGPT interface. OpenAI has not revealed technical details and statistics about GPT-4, such as the precise size of the model. The term « hallucination » as applied to LLMs is distinct from its meaning in psychology, and the phenomenon in chatbots is more similar to confabulation or bullshitting. A 2023 analysis estimated that ChatGPT hallucinates around 3% of the time.
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.
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.
It has an additional feature called « agentic mode » that allows it to take online actions for the user. The laborers were exposed to toxic 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).
- Most people don’t explore that space.
- ChatGPT has a familiar rhythm that most people recognize, even if they cannot describe it.
- At launch, OpenAI included more than 3 million GPTs created by GPT Builder users in the GPT Store.
- 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.
- Some, including Nature and JAMA Network, « require that authors disclose the use of text-generating tools and ban listing a large language model (LLM) such as ChatGPT as a co-author ».
- At launch, the feature was limited to purchases on Etsy from US users with a payment method linked to their OpenAI account.
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.
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 ».
