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.

DALL-E 3 Made Available in ChatGPT Plus and Enterprise (October

• It is capable of writing software, answering codebase questions, running tests, and proposing pull requests.
• 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.
• An upgrade to Google AI Pro, which costs $19.99 a month, unlocks the latest model, as well as coding tools, the Gemini assistant in Chrome, and access to Gemini in Google apps.
• The free version lacks advanced data analysis features and the ability to create custom GPTs.
• The ethics of its development, particularly the use of copyrighted content as training data, have also drawn controversy.
• GPT-5 was launched on August 7, 2025, and is publicly accessible through ChatGPT, Microsoft Copilot, and via OpenAI’s API.
• ChatGPT’s reliance on data found online makes it vulnerable to false information, which in turn can impact the veracity of its statements.

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.

Notable ChatGPT Updates

The Pro launch coincided with the release of the o1 model, providing unlimited access to o1 and advanced voice mode. The model can also generate new images based on existing ones provided in the prompt, which can, for example, be used to transform images with specific styles or inpaint areas. 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. ChatGPT is a goatz casino review chatbot and AI assistant built on large language model (LLM) technology.

Edit, Translate and Summarize Content

Geoffrey Hinton, one of the "fathers of AI", voiced concerns that future AI systems may surpass human intelligence. 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". 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. 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. ChatGPT gained one million users in five days and 100 million in two months, becoming the fastest-growing internet application in history.

Intuit Apps Integrated With ChatGPT (November

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.

• “With Gemini 3, it seems like it is processing text, video, audio, and code in a unified manner,” Kejriwal said.
• “We’ll use language models to help us write first drafts, to brainstorm.
• The FTC asked OpenAI for comprehensive information about its technology and privacy safeguards, as well as any steps taken to prevent the recurrence of situations in which its chatbot generated false and derogatory content about people.
• The chatbot technology can improve security by cyber defense automation, threat intelligence, attack identification, and reporting.
• Not only can ChatGPT generate working computer code of its own (in many different languages), but it can also translate code from one language to another, and debug existing code.
• 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.

What are the main ChatGPT competitors?

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's training data includes software manual pages, information about internet phenomena such as 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.

Image and Voice Recognition and Text to Speech Features Release (September

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.
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.
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.
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.
