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. ChatGPT’s training data only covers a period up to the cut-off date, so it lacks knowledge of recent events.
What can I do with ChatGPT?
ChatGPT Team lets companies create shared workspaces with settings that apply to all users, as well as the ability to share proprietary data sets. To kick off the start of its o1 model family, OpenAI also announces the limited release of its o1-preview and o1-mini models. OpenAI initially released this feature to users who pay for the Plus, Team or Enterprise plan. OpenAI released GPT-5, calling it its “fastest” and “smartest” AI model to date.
GPT-5 vs. GPT 4o
OpenAI’s outsourcing partner was Sama, a training-data company based in San Francisco, California. 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. As of 2025, ChatGPT’s website is among the top 5 most-visited websites globally, and has over 800 million active weekly users. By January 2023, ChatGPT had become the fastest-growing consumer software application in history, gaining over 100 million users in two months.
Kelsey Piper of Vox wrote that “ChatGPT is the general public’s first hands-on introduction to how powerful modern AI has gotten” and that ChatGPT is “smart enough to be useful despite its flaws”. 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”. As before, OpenAI has not disclosed technical details such as the exact number of parameters or the composition of its training dataset. GPT-5 was launched on August 7, 2025, and is publicly accessible through ChatGPT, Microsoft Copilot, and via OpenAI’s API.
Biased Responses
- It’s capable of carrying on conversations with human users and generating a wide range of text outputs including recipes, computer code, essays and personal letters.
- Once you’ve chosen a model and even a mode or tool in ChatGPT, it’s time to finally ask something.
- None of the tested services were a perfect replacement for a fluent human translator.
- 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.
- Initially released as a pilot, group chats will be steadily released globally to all logged-in ChatGPT Free, Go, Plus and Pro users.
The user can interrupt tasks or provide additional instructions as needed. In July 2025, OpenAI released ChatGPT agent, an AI agent that can perform multi-step tasks. It was controlling a software environment inside a virtual machine with limited internet connectivity and with safety restrictions. In 2025, OpenAI added several features to make ChatGPT more agentic (capable of autonomously performing longer tasks). According to TechCrunch, it is a service based on o3 that combines advanced reasoning and web search capabilities to make comprehensive reports within 5 to 30 minutes. This tool allows a user to customize ChatGPT’s behavior for a specific use case.
- ChatGPT (based on GPT-4) was better able to translate Japanese to English when compared to Bing, Bard, and DeepL Translator in 2023.
- They can explicitly tell ChatGPT to remember aspects of the conversation, and ChatGPT can use these details in future conversations.
- This includes text-to-image models such as Stable Diffusion and large language models such as ChatGPT.
- 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.
- OpenAI has faced quite a bit of criticism for how students can use ChatGPT to cheat on their homework or exams, and the company.introduced a study mode tool to directly address those concerns.
- Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.
Applications
The feature is also still exclusive to ChatGPT users who have a Plus, Team, Enterprise or Education plan. Advanced voice mode becomes available on web browsers — before, it could only be accessed on mobile and desktop formats. While users cannot checkout inside ChatGPT, they are redirected to the merchant’s website when they click on the link. 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.
OpenAI announces the ChatGPT Pro plan, a new premium plan for ChatGPT users to access even more features. The partnership also involves Intuit deepening its use of OpenAI’s frontier models to support a range of use cases on its platform, including powering select AI agents and improving employee productivity at Intuit. With users’ permission, these apps will be able to access their financial data and offer personalized financial insights and recommendations, as well as review credit cards, personal loans and mortgages. In August 2025, OpenAI released GPT-5, its fastest and smartest model to date, and the current language model for ChatGPT.
About this app
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. To prevent offensive outputs from being presented to and produced by ChatGPT, queries are filtered through the OpenAI “Moderation endpoint” API (a separate GPT-based AI). They can explicitly tell ChatGPT to remember aspects of the conversation, and ChatGPT can use these details in future conversations. Users interact with ChatGPT through conversations which consist of text, audio, and image inputs and outputs.
Kevin Roose of The New York Times called it “the best artificial intelligence chatbot ever released to the general public”. Like GPT-5, it comes with a “Thinking” mode for complex problem-solving and an “Instant” mode for fast responses. According to OpenAI, it features reduced hallucinations and enhanced pattern recognition, creativity, and user interaction. Released in February 2025, GPT-4.5 was described by Altman as a “giant, expensive model”.
So far, users can make single-item purchases from domestic sellers on online marketplace Etsy, as well as some merchants on Shopify’s e-commerce platform. OpenAI announced that it is letting users buy goods directly in ChatGPT through a feature called Instant Checkout. The company also partnered with PayPal, one of the largest payment processing services in the world, to let users pay for their shopping directly within ChatGPT. This feature keeps group chats separate from personal conversations within ChatGPT, where adding another user to an existing chat creates a copy of the original conversation. OpenAI announced group chats as a ChatGPT feature, allowing users in select regions to collaborate with each other — and with the AI — in a shared conversation for planning, decision-making or working through ideas.
■ Shopping research turns ChatGPT into a personal assistant
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. 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. It is designed to generate human-like text and can carry out a wide variety of tasks.
These limitations may be revealed when ChatGPT responds to prompts including descriptors of people. ChatGPT can find more up-to-date information by searching the web, but this doesn’t ensure that responses are accurate, as it may access unreliable or misleading websites. OpenAI acknowledged that there have been “instances where our 4o model fell short in recognizing signs of delusion or emotional dependency”, and reported that it is working to improve safety.
ChatGPT is a chatbot created by OpenAI that can process text, image, audio and video data to answer questions, solve problems and more. 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. This has led to concern over the rise of what has come to be called “synthetic media” and “AI slop” which are generated by AI and rapidly spread over social media and the internet. 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”. 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. 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.
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. 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. … 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.
This is used to not only help the model determine the best output, but it also helps improve the training process, enabling it to answer questions more effectively. This approach incorporates human feedback into vegas casino the training process so it can better align its outputs with user intent (and carry on with more natural-sounding dialogue). 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). It can also critique the user’s writing, summarize long documents and translate text from one language to another.
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. Following the addition of agentic e-commerce and easy checkout features, OpenAI partnered with Walmart, the country’s largest retailer to enhance digital shopping experiences. This could enable ChatGPT to keep track of larger documents and conversations, and to handle more complex projects. Teachers are concerned that students will use it to cheat, prompting some schools to completely block access to it.
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.
In Mata v. Avianca, Inc., a personal injury lawsuit filed in May 2023, the plaintiff’s attorneys used ChatGPT to generate a legal motion. Many companies adopted ChatGPT and similar chatbot technologies into their product offers. The dangers are that “meaningless content and writing thereby becomes part of our culture, particularly on social media, which we nonetheless try to understand or fit into our existing cultural horizon.” The Guardian questioned whether any content found on the Internet after ChatGPT’s release “can be truly trusted” and called for government regulation.
“There are things that have existed in the past that these statistically oriented models will then pick up on, but we don’t want to project those associations into the future. 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. 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.
