Originally released on November 30, 2022, the product uses large language models—specifically generative pre-trained transformers (GPTs)—to generate text, speech, and images in response to user prompts. ChatGPT accelerated the AI boom, an ongoing period marked by rapid investment and public attention toward the field of artificial intelligence (AI). OpenAI operates the service on a freemium model. Users can interact with ChatGPT through text, audio, and image prompts. ChatGPT was quickly adopted, reaching 100 million monthly active users two months after its release and 900 million weekly active users in February 2026. Proponents say that it has the potential to transform numerous professional fields, and it has instigated public debate about the nature of creativity and the future of knowledge work. The chatbot has also been criticized for its limitations and potential for unethical use. It can generate plausible-sounding but incorrect or nonsensical answers, known as hallucinations. Biases in its training data have been reflected in its responses. The chatbot can facilitate academic dishonesty, generate misinformation, and create malicious code. The ethics of its development, particularly the use of copyrighted content as training data, have also drawn controversy. Features ChatGPT is a chatbot assistant based on large language model (LLM) technology.[4] It is designed to generate human-like text and can carry out a wide variety of tasks. These include, among many others, writing and debugging computer programs, composing music, scripts, fairy tales, and essays, answering questions (sometimes at a level exceeding that of an average human test-taker),[5] and generating business concepts.[6] ChatGPT is frequently used for translation and summarization tasks,[7][8] and can simulate interactive environments such as a Linux terminal,[9] a multi-user chat room,[9] or simple text-based games such as tic-tac-toe.[9] Users interact with ChatGPT through conversations which consist of text, audio, and image inputs and outputs.[10] The user's inputs to these conversations are referred to as prompts.[11] An optional "Memory" feature allows users to tell ChatGPT to memorize specific information. Another option allows ChatGPT to recall old conversations.[12] GPT-based moderation classifiers are used to reduce the risk of harmful outputs being presented to users.[13] In March 2023, OpenAI added support for plugins for ChatGPT.[14] This includes both plugins made by OpenAI, such as web browsing and code interpretation, and external plugins from developers such as Expedia, OpenTable, and Zapier.[15] From October to December 2024, ChatGPT Search was deployed.[16] It allows ChatGPT to search the web in an attempt to make more accurate and up-to-date responses.[17][18] It increased OpenAI's direct competition with major search engines.[19] OpenAI allows businesses to tailor how their content appears in the ChatGPT Search results and influence what sources are used.[19] 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.[20] In October 2025, OpenAI launched ChatGPT Atlas, a browser integrating the ChatGPT assistant directly into web navigation, to compete with existing browsers such as Google Chrome. It has an additional feature called "agentic mode" that allows it to take online actions for the user.[21] Paid tier ChatGPT was initially free to the public and remains free in a limited capacity.[22] In February 2023, OpenAI launched a premium service, ChatGPT Plus, that costs US$20 per month.[23] What was offered on the paid plan versus the free tier changed as OpenAI has continued to update ChatGPT, and a Pro tier at $200/mo was introduced in December 2024.[24][25] The Pro launch coincided with the release of the o1 model.[25] In August 2025, ChatGPT Go was offered in India for ₹399 per month. The plan has higher limits than the free version.[26] Mobile apps In May-July 2023, OpenAI began offering ChatGPT iOS and Android apps.[27] ChatGPT can also power Android's assistant.[28] An app for Windows launched on the Microsoft Store on October 15, 2024.[29] Languages OpenAI met Icelandic President Guðni Th. Jóhannesson in 2022. In 2023, OpenAI worked with a team of 40 Icelandic volunteers to fine-tune ChatGPT's Icelandic conversation skills as part of Iceland's attempts to preserve the Icelandic language.[30] ChatGPT (based on GPT-4) was better able to translate Japanese to English when compared to Bing, Bard, and DeepL Translator in 2023.[7] 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.[31] Several studies have shown that ChatGPT can outperform Google Translate in some mainstream translation tasks. However, as of 2024, no machine translation services match human expert performance.[32][33] GPTs and plugins Main article: GPT Store In November 2023, OpenAI released GPT Builder, a tool allowing users to customize ChatGPT's behavior for a specific use case.[34] The customized systems are referred to as GPTs. In January 2024, OpenAI launched the GPT Store, a marketplace for GPTs.[35][36][34] At launch, OpenAI included more than 3 million GPTs created by GPT Builder users in the GPT Store.[37] In September 2025, OpenAI added support for Model Context Protocol (MCP) to ChatGPT apps. When enabled in developer mode, this allows for improved third-party access to ChatGPT tools and servers.[38] In July 2026, ChatGPT apps were renamed to plugins.[39] Deep Research Main article: ChatGPT Deep Research In February 2025, OpenAI released Deep Research, a feature that generates reports based on extensive web searches. It was initially based on the reasoning model o3 and took 5 to 30 minutes per report.[40] Images Screenshot of ChatGPT showing a generated image representing the online encyclopedia Wikipedia as a glowing digital library In October 2023, OpenAI's image generation model DALL-E 3 was integrated into ChatGPT. The integration used ChatGPT to write prompts for DALL-E guided by conversations with users.[41][42] In March 2025, OpenAI updated ChatGPT to generate images using GPT Image instead of DALL-E. One of the most significant improvements was in the generation of text within images, which is especially useful for branded content. However, this ability is noticeably worse in non-Latin al…
