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. Prior to ChatGPT, OpenAI launched several products, including automatic speech recognition software Whisper, and DALL-E, an AI art generator that can produce images based on text prompts.
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 technology can improve security by cyber defense automation, threat intelligence, attack identification, and reporting. In July 2024, Futurism reported that GPT-4o in ChatGPT would sometimes link “scam news sites that deluge the user with fake software updates and virus warnings”; these pop-ups can be used to coerce users into downloading malware or potentially unwanted programs. In an industry survey, cybersecurity professionals argued that it was attributable to cybercriminals’ increased use of generative artificial intelligence (including ChatGPT). Chris Granatino, a librarian at Seattle University, noted that while ChatGPT can generate content that seemingly includes legitimate citations, in most cases those citations are not real or largely incorrect.
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.
Shortly after the bug was fixed, users could not see their conversation history. 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.
In The Atlantic magazine’s “Breakthroughs of the Year” for 2022, Derek Thompson included ChatGPT as part of “the generative-AI eruption” that “may change our mind about how we work, how we think, and what human creativity is”. Like GPT-5, it comes with a “Thinking” mode for complex problem-solving and an “Instant” mode for fast responses. GPT-5 was launched on August 7, 2025, and is publicly accessible through ChatGPT, Microsoft Copilot, and via OpenAI’s API.
How does ChatGPT work?
- ChatGPT’s reliance on data found online makes it vulnerable to false information, which in turn can impact the veracity of its statements.
- This update allows users to create customized GPTs that follow specific instructions and knowledge provided by the builder.
- ChatGPT is frequently used for translation and summarization tasks, and can simulate interactive environments such as a Linux terminal, a multi-user chat room, or simple text-based games such as tic-tac-toe.
- OpenAI has already gotten a glimpse of this future through its o1 model, and the results have been mixed.
- ChatGPT Team lets companies create shared workspaces with settings that apply to all users, as well as the ability to share proprietary data sets.
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.
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.
GPT-5 vs. GPT 4o
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. In September 2025, following the suicide of a 16-year-old, OpenAI said it planned to add restrictions for users under 18, including the blocking of graphic sexual content and the prevention of flirtatious talk. OpenAI CEO Sam Altman said that users were unable to see the contents of the conversations. 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. According to research conducted by OpenAI and AI safety organization Apollo Research, o1 provides more intelligent answers than GPT-4o while also attempting to deceive users more than any major AI model available.
Applications
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. This approach incorporates human feedback into the training process so it can better align its outputs with user intent (and carry on with more natural-sounding dialogue). ChatGPT is powered by a large language model made up of neural networks trained on a massive amount of information from the internet, including Wikipedia articles and research papers. 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”. Some, including Nature and JAMA Network, “require that authors disclose the use of text-generating tools and ban listing a large language model (LLM) such as ChatGPT as a co-author”. 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.
Biased Responses
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.
App support
- OpenAI collects data from ChatGPT users to further train and fine-tune its services.
- ChatGPT’s training data only covers a period up to the cut-off date, so it lacks knowledge of recent events.
- 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 pin-up casino india 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.
What Is ChatGPT?
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.
GPT Store Launch (January
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.
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.
