ChatGPT's training data includes software manual pages, information about internet phenomena such as goatz casino review bulletin board systems, multiple programming languages, and the text of Wikipedia. These labels were used to train a model to detect such content in the future. 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.
Where can you access ChatGPT-5 versus Gemini 3?
In late March 2023, the Italian data protection authority banned ChatGPT in Italy and opened an investigation. Stanford researchers reported that GPT-4 "passes a rigorous Turing test, diverging from average human behavior chiefly to be more cooperative." 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. A 2023 study reported that GPT-4 obtained a better score than 99% of humans on the Torrance Tests of Creative Thinking. The company announced a slew of generative AI-powered features to counter OpenAI and Microsoft.
ChatGPT has never been publicly available in China because OpenAI prevented Chinese users from accessing their site. 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. OpenAI CEO Sam Altman said that users were unable to see the contents of the conversations. … It's also a way to understand the "hallucinations", or nonsensical answers to factual questions, to which large language models such as ChatGPT are all too prone. In March 2023, ChatGPT Plus users got access to third-party plugins and a browsing mode (with Internet access). Premium users were originally limited in the number of messages they could send to the new model, but OpenAI increased and eventually removed these limits.
GPT-4o
As first reported by The Information, Sam Altman sent employees a memo outlining a "code red" situation and calling for rapid improvements to ChatGPT, a sign that OpenAI is taking Google's latest advance seriously. After ChatGPT blindsided the company in 2022 and turned OpenAI into the face of generative AI, Google spent three years working to regain its footing.
In Mata v. Avianca, Inc., a personal injury lawsuit filed in May 2023, the plaintiff's attorneys used ChatGPT to generate a legal motion. 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. The chatbot can assist patients seeking clarification about their health. Many companies adopted ChatGPT and similar chatbot technologies into their product offers.
How do ChatGPT-5.1 and Gemini 3 compare in price?
OpenAI announces the ChatGPT Pro plan, a new premium plan for ChatGPT users to access even more features. However, it was labeled underwhelming by some users due its performance shortly after its release. OpenAI released GPT-5, calling it its “fastest” and “smartest” AI model to date.
One such workaround, popularized on Reddit in early 2023, involved making ChatGPT assume the persona of "DAN" (an acronym for "Do Anything Now"), instructing the chatbot that DAN answers queries that would otherwise be rejected by the content policy. Despite this, users may "jailbreak" ChatGPT with prompt engineering techniques to bypass these restrictions. 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, the feature was limited to purchases on Etsy from US users with a payment method linked to their OpenAI account. In July 2025, OpenAI released ChatGPT agent, an AI agent that can perform multi-step tasks. It was capable of autonomously performing tasks through web browser interactions, including filling forms, placing online orders, scheduling appointments, and other browser-based tasks.
- In August 2024, OpenAI announced it had created a text watermarking method but did not release it for public use, saying that users would go to a competitor without watermarking if it publicly released its watermarking tool.
- Released by artificial intelligence company OpenAI in 2022, ChatGPT is a chatbot capable of communicating with users in a human-like way.
- In March 2025, OpenAI updated ChatGPT to generate images using GPT-4o instead of DALL-E.
- But it’s OpenAI’s plan to launch AI agents in 2025 that could bring it close to its ultimate goal of achieving artificial general intelligence (AGI), where a machine can behave and perform actions the way humans can.
- The company also unveiled an open-source technical standard called Agentic Commerce Protocol for merchants to build integrations with ChatGPT, essentially making their products available for purchase within the chatbot.
- It can generate plausible-sounding but incorrect or nonsensical answers known as hallucinations.
ChatGPT’s reliance on data found online makes it vulnerable to false information, which in turn can impact the veracity of its statements. ChatGPT can also be accessed as a mobile app on iOS and Android devices. ChatGPT can be used for other writing tasks beyond just content creation.
- This includes text-to-image models such as Stable Diffusion and large language models such as ChatGPT.
- But then the value of domain experts will continue to refine that and make it better than whatever a model can produce.”
- This is used to not only help the model determine the best output, but it also helps improve the training process, enabling it to answer questions more effectively.
- It uses a generative pre-trained transformer (GPT), to generate text, speech, and images in response to user prompts.
- OpenAI announces the release of its o1 model, which demonstrates complex reasoning capabilities.
- Initially released as a pilot, group chats will be steadily released globally to all logged-in ChatGPT Free, Go, Plus and Pro users.
ChatGPT is a chatbot created by OpenAI that can process text, image, audio and video data to answer questions, solve problems and more. The Guardian questioned whether any content found on the Internet after ChatGPT's release "can be truly trusted" and called for government regulation. 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". The chatbot technology can improve security by cyber defense automation, threat intelligence, attack identification, and reporting.
As of 2023, there were several pending U.S. lawsuits challenging the use of copyrighted data to train AI models, with defendants arguing that this falls under fair use. 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.

In August 2024, OpenAI announced it had created a text watermarking method but did not release it for public use, saying that users would go to a competitor without watermarking if it publicly released its watermarking tool. GPT-4, which was released on March 14, 2023, was made available via API and for premium ChatGPT users. ChatGPT is a generative artificial intelligence chatbot developed by OpenAI and released in November 2022. In October, OpenAI launched a browser called Atlas that allows users to access GPT straight from the browser. For a professional power user, there is also ChatGPT Pro at $200 a month, which provides unlimited access to all of OpenAI's models and offers prioritized response times at peak hours. The model has been trained through a combination of automated learning and human feedback to generate text that closely matches what you’d expect to see in text written by a human.
Later reports showed the bug was much more severe than initially believed, with OpenAI reporting that it had leaked users' "first and last name, email address, payment address, the last four digits (only) of a credit card number, and credit card expiration date". 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.
None of the tested services were a perfect replacement for a fluent human translator. For more common languages, AI translators like ChatGPT did better than Google Translate, while for "niche" languages (Amharic and Tagalog), Google Translate performed better. The languages tested were Polish, French, Korean, Spanish, Arabic, Tagalog, and Amharic. In December 2023, the Albanian government decided to use ChatGPT for the rapid translation of European Union documents and the analysis of required changes needed for Albania's accession to the EU. 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.

“There are things that have existed in the past that these statistically oriented models will then pick up on, but we don’t want to project those associations into the future. Ravinutala said chatbots like ChatGPT can be used by customer experience companies to automate customer service interactions, allowing companies to better understand user intent and respond accordingly. Instead of a list of websites, though, it’ll provide users with a simple list of answers. It can also be fine-tuned for specific use cases such as legal documents or medical records, where the model is trained on domain-specific data. It can translate a piece of text into different languages, summarize several pages of text into a paragraph, finish a partially complete sentence, generate dialogue and more.
Teachers are concerned that students will use it to cheat, prompting some schools to completely block access to it. But then the value of domain experts will continue to refine that and make it better than whatever a model can produce.” So, despite the guardrails OpenAI has put in place to prevent it, the chatbot still has a tendency to let biases creep into its outputs. And, because the model is able to produce incorrect information in such an eloquent way, the fallacies are hard to spot and control. This often leads to what experts call “hallucinations,” where the output generated is stylistically correct, but factually wrong.
Released by artificial intelligence company OpenAI in 2022, ChatGPT is a chatbot capable of communicating with users in a human-like way. It’s capable of carrying on conversations with human users and generating a wide range of text outputs including recipes, computer code, essays and personal letters. The GPT in ChatGPT stands for “general pre-trained transformer,” which is a language model that uses deep learning and natural language processing to generate natural, human-like text based on a given text input. 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.
