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. TrendForce market intelligence estimated that 30,000 Nvidia GPUs (each costing approximately $10,000–15,000) were used to power ChatGPT in 2023. In October 2023, OpenAI’s image generation model DALL-E 3 was integrated into ChatGPT Plus and ChatGPT Enterprise. According to the company, the paid version of the website was still experimental, but provided access during peak periods, no downtime, priority access to new features, and faster response speeds.

GPT-4, which was released on March 14, 2023, was made available via API and for premium ChatGPT users. 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. ChatGPT is a chatbot and AI assistant built on large language model (LLM) technology. 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.
Instant Checkout Feature Release (September
- In December 2022, the question-and-answer website Stack Overflow banned the use of ChatGPT for generating answers to questions, citing the factually ambiguous nature of its responses.
- This can include factual information — like dietary restrictions or relevant details about the user’s business — as well as stylistic preferences like brevity or a specific kind of outline.
- It currently uses GPT-5.1, a generative pre-trained transformer (GPT), to generate text, speech, and images in response to user prompts.
- 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.
On November 29, Rosário revealed that the bill had been entirely written by ChatGPT, and that he had presented it to the rest of the council without making any changes or disclosing the chatbot’s involvement. The attorneys were sanctioned for filing the motion and presenting the fictitious legal decisions ChatGPT generated as authentic. In Mata v. Avianca, Inc., a personal injury lawsuit filed in May 2023, the plaintiff’s attorneys used ChatGPT to generate a legal motion.
- This update allows users to interact with ChatGPT via speech, and to upload images that the model can analyze and use to generate outputs.
- While users cannot checkout inside ChatGPT, they are redirected to the merchant’s website when they click on the link.
- In August 2025, OpenAI released GPT-5, its fastest and smartest model to date, and the current language model for ChatGPT.
At $200 per month, the plan is intended to give users access to OpenAI’s latest offering, the o1 model family. The language models used in ChatGPT are specifically optimized for dialogue and were trained using reinforcement learning from human feedback (RLHF). By using a large language model (LLM), which is trained on vast amounts of data from the internet, ChatGPT can answer questions, compose essays, offer advice and write code in a fluent and natural way. 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. 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.
App support
GPT-4o (“o” for “omni”) is a multilingual, multimodal generative pre-trained transformer developed by OpenAI and released in May 2024. A study presented example attacks on ChatGPT, including jailbreaks and reverse psychology. ChatGPT is programmed to reject prompts that may violate its content policy. 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. In one instance, ChatGPT generated a rap in which women and scientists of color were asserted to be inferior to white male scientists.
Advanced voice mode becomes available on web browsers — before, it could only be accessed on mobile and desktop formats. For example, ChatGPT will offer hints, organize content into sections and create custom lessons and quizzes instead of providing a direct answer to students. Based on internal evaluations, GPT-5 outperforms its predecessors in multiple areas, including math, coding, visual perception and health knowledge. 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. GPT-5 also added enhanced multimodal capabilities with improvements to email, calendar and code environment integrations. This could enable ChatGPT to keep track of larger documents and conversations, and to handle more complex projects.
In March 2023, a bug allowed some users to see the titles of other users’ 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. The integration used ChatGPT to write prompts for DALL-E guided by conversations with users. 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.
What Is ChatGPT?
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. ChatGPT is one of many AI content generators tackling the art of the written word — whether that be a news article, press release, college essay or sales email.
A 2025 Sentio University survey of 499 LLM users with self-reported mental health conditions found that 96.2% use ChatGPT, with 48.7% using it specifically for mental health support or therapy-related purposes. At launch, the feature was limited to purchases on Etsy from US users with a payment method linked to their OpenAI account. It was capable of autonomously performing tasks through web browser interactions, including filling forms, placing online orders, scheduling appointments, and other browser-based tasks. At launch, OpenAI included more than 3 million GPTs created by GPT Builder users in the GPT Store. The Pro launch coincided with the release of the o1 model, providing unlimited access to o1 and advanced voice mode. 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.
ChatGPT Plus Launch (February
OpenAI announced the addition of product recommendations on ChatGPT when users implied shopping intent in their queries. ChatGPT Agent functions by using a text-based browser to find information related to the action requested by the user. The new feature enables the chatbot to start and complete tasks on behalf of the user with minimal input. However, it was labeled underwhelming by some users due its performance shortly after its release. It is now available to both paying and non-paying ChatGPT users, with usage limitations of course.
Users can upvote or downvote responses they receive from ChatGPT and fill in a text field with additional feedback. 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). These issues have led to its use being restricted in some workplaces and educational institutions and have prompted widespread calls for the regulation of artificial intelligence.
Frequently Asked Questions
It can generate plausible-sounding but incorrect or nonsensical answers known as hallucinations. Despite its acclaim, the chatbot has been criticized for its limitations and potential for unethical use. It is credited with accelerating the AI boom, an ongoing period marked by rapid investment and public attention toward the field of artificial intelligence (AI).
Released by artificial intelligence company OpenAI in 2022, ChatGPT is a chatbot capable of communicating with users in a human-like way. 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 the 2020s, the rapid advancement of deep learning-based generative artificial intelligence models raised questions about the copyright status of AI-generated works, and about whether copyright infringement occurs when such are trained pin-up casino india or used. In October 2025, OpenAI reported that approximately 0.15% of ChatGPT’s active users in a given week have conversations including explicit indicators of potential suicidal planning or intent, translating to more than a million people weekly. Over many iterations of ChatGPT, plus users maintained more access to better models than the free tier provided, and access to additional features like voice mode.
Help With Customer Service
Custom instructions allow users to save directions that apply to all interactions, rather than adding them to every request. The newest version of OpenAI’s image generator, DALL-E, was made available to ChatGPT Plus and Enterprise users. This update allows users to create customized GPTs that follow specific instructions and knowledge provided by the builder.
Most people know that, just because something is on the internet, that doesn’t make it true. 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.
In March 2025, OpenAI updated ChatGPT to generate images using GPT-4o instead of DALL-E. It allows ChatGPT to search the web in an attempt to make more accurate and up-to-date responses. This includes both plugins made by OpenAI, such as web browsing and code interpretation, and external plugins from developers such as Expedia, OpenTable, Zapier, Shopify, Slack, and Wolfram.
And it has affected how everyday people experience the internet in “profound ways,” according to Raghu Ravinutala, the co-founder and CEO of customer experience startup Yellow.ai. OpenAI, an AI research company based in San Francisco, created ChatGPT, releasing it publicly on November 30, 2022. In order to sift through terabytes of internet data and transform that into a text response, ChatGPT uses a technique called transformer architecture (hence the “T” in its name). Here’s how it works, its use cases, how to access it, its limitations, notable updates and future outlook.
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. In December 2022, the question-and-answer website Stack Overflow banned the use of ChatGPT for generating answers to questions, citing the factually ambiguous nature of its responses. ChatGPT was able in 2023 to provide useful code for solving numerical algorithms in limited cases. 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. It found that 52% of the responses contained inaccuracies and 77% were verbose. One study analyzed ChatGPT’s responses to 517 questions about software engineering or computer programming posed on Stack Overflow for correctness, consistency, comprehensiveness, and concision.
