Download ChatGPT free for Windows, macOS, Android, APK, iOS and Web App

ChatGPT is a chatbot and AI assistant built on large language model (LLM) technology. Microsoft's applications benefit from task automation and content summarization, which enables the system to generate reports directly from their user interfaces. The chatbot language model driven by AI - Google Gemini, which was created by Google, is a direct rival of ChatGPT. Computer users can only access ChatGPT through their browser until OpenAI completes its development of native desktop applications for different operating systems. Through official mobile apps for both the iOS and Android operating systems, users can easily access ChatGPT from any location. The paid version is appropriate for users who require continuous access to advanced AI benefits, while the free version is suitable for those who are happy with basic general usage.

• While ChatGPT specializes in text, OpenAI has developed other tools that expand creative possibilities.
• Stanford researchers reported that GPT-4 "passes a rigorous Turing test, diverging from average human behavior chiefly to be more cooperative."
• Reinforcement learning consisted of human trainers ranking responses generated by the model in previous conversations.
• In medical education, it can explain concepts, generate case scenarios, and be used by students preparing for licensing examinations.

In July 2023, the US Federal Trade Commission (FTC) issued a civil investigative demand to OpenAI to investigate whether the company's data security and privacy practices to develop ChatGPT were unfair or harmed consumers. 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."

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. Despite this, users may jailbreak ChatGPT with prompt engineering techniques to bypass these restrictions.

The tool functions as an essential platform because it allows people to accomplish tasks more efficiently and handles complex operations in a short amount of time.

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 one study, it produced solutions in C, C++, Python, and MATLAB for problems in computational physics. 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. Additionally, using a model's outputs might violate copyright, and the model creator could be accused of vicarious liability and held responsible for that copyright infringement.citation needed When assembling training data, the sourcing of copyrighted works may infringe on the copyright holder's exclusive right to control reproduction, unless covered by exceptions in relevant copyright laws. A May 2023 statement by hundreds of AI scientists, AI industry leaders, and other public figures demanded that "mitigating the risk of extinction from AI should be a global priority". Geoffrey Hinton, one of the "fathers of AI", voiced concerns that future AI systems may surpass human intelligence.

In November 2023, OpenAI released GPT Builder, a tool allowing users to customize ChatGPT's behavior for a specific use case. 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. GPT-based moderation classifiers are used to reduce the risk of harmful outputs being presented to users. An optional "Memory" feature allows users to tell ChatGPT to memorize specific information.

ChatGPT is frequently used for translation and summarization tasks, and can simulate krikya-online.com interactive environments such as a Linux terminal, a multi-user chat room, or simple text-based games such as tic-tac-toe. It is designed to generate human-like text and can carry out a wide variety of tasks. The ethics of its development, particularly the use of copyrighted content as training data, have also drawn controversy. The chatbot can facilitate academic dishonesty, generate misinformation, and create malicious code. ChatGPT was quickly adopted, reaching 100 million monthly active users two months after its release and 900 million weekly active users in February 2026. The developer has not yet indicated which accessibility features this app supports.

Through OpenAI platform development, OpenAI built ChatGPT as an advanced conversational AI able to generate natural human language from received inputs. In an American civil lawsuit, attorneys were sanctioned for filing a legal motion generated by ChatGPT containing fictitious legal decisions. However, 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. ChatGPT can provide health information to users and assist professionals with diagnosis and staying up to date with clinical guidelines. 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".
