According to OpenAI, study mode is powered by custom system instructions written in collaboration with teachers, scientists and educational experts. Initially, OpenAI was a non-profit focused on developing artificial intelligence “in the way that is more likely to benefit humanity as whole, unconstrained by a need to generate financial return,” according to a statement from 2015. ChatGPT, short for Generative Pre-trained Transformer, is a conversational AI chatbot capable of understanding and generating human-like text in response to a user’s questions and prompts. OpenAI released GPT-5, calling it its “fastest” and “smartest” AI model to date.
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. 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. According to OpenAI’s privacy policy, ChatGPT does not use end-to-end encryption, and all chat histories are stored and may be used to train future models. Consequently, users are advised not to “share sensitive information, such as passwords, credit card numbers, or similar information, via the chat”.

This means that anything you tell ChatGPT or any files uploaded onto the platform are kept by OpenAI. In 2025, the UK government struck a partnership with OpenAI to deploy advanced AI models in security research and to explore AI’s role in public services. PwC stands out on the corporate front as OpenAI’s first reseller and largest enterprise user, deploying ChatGPT Enterprise to more than 100,000 staff across the UK and US. Its reliance on existing internet content leads critics to question whether its outputs amount to plagiarism or unfair use of original work. Simultaneously, there is debate over whether its efficiency in helping to eradicate menial and time-consuming tasks may prompt job displacement in roles traditionally handled by humans. ChatGPT forms coherent responses to user prompts, drawing on patterns and structures observed during training, allowing it to become a generative AI that creates new content.
It can perform tasks like filling out forms, ordering groceries, booking travel, and conducting research by mimicking human actions such as clicking, typing, and scrolling. The TL;DR is, GPT-4o mini is free for all users, while other models, like GPT-4o, o1, o3-mini, and o3-mini-high, require a subscription to access and come with their own usage limits. ZDNET’s recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.
This is a business version of the system that mitigates privacy concerns around client data by preventing training on proprietary content. Similarly, OpenAI developed ChatGPT Edu to deploy AI system to students, faculty, researchers and campus operations that can reason across text and offer further data security. As of 2025, the company is valued at approximately $300bn, a valuation propelled by breakthrough models like ChatGPT. As before, OpenAI has not disclosed technical details such as the exact number of parameters or the composition of its training dataset. OpenAI has made it possible to use ChatGPT instantly without creating an account.

- 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.
- Similar to a phone’s auto-complete feature, ChatGPT uses a prediction model to guess the most likely next word based on the context it has been provided.
- The release of GPT-5 provides a sizable update to previous models, at least on paper.
The system uses this information and training to predict the next most probable word in a sentence. By January 2023, ChatGPT had become the fastest-growing consumer software application in history, gaining over 100 million users in two months.89 Users can interact with ChatGPT through text, audio, and image prompts. It has been lauded as a revolutionary tool that could transform numerous professional fields.
The plan costs $200 per month and gives users access to Open AI chart of accounts definition o1, o1-mini, GPT-4o and advanced voice mode. “It actually integrates and systematizes humans’ subjective judgment into the model training process,” Sam Stone, the director of product management, pricing and data products at real estate tech firm Opendoor, told Built In. 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. 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. This allows ChatGPT to take a sequence of words a user gives it, such as a half-completed sentence, and fill in the blanks with the most statistically probable word given the surrounding context — sort of like auto-complete.
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. The company states that the new AI model is “smarter across the board, as reflected by its performance on academic and human-evaluated benchmarks, particularly in math, coding, visual perception, and health”. For businesses seeking stronger protections, OpenAI’s Enterprise, Edu and Team offerings ensure that customer data is neither used for training purposes nor shared. The answers will adopt a confident tone, and will normally end with an expanding question that aims to prompt you to continue to use the AI. ChatGPT handles an extraordinarily wide range of tasks due to its level of access to internet sources and training. Any AI is a computer system designed to perform tasks that normally need human intelligence.
Some developers were so excited by ChatGPT’s capabilities that they used it to actually create their own apps, including a spreadsheet assistant capable of performing complex calculations in response to a simple request. 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. These stem from data gaps, biased training inputs, or flawed model assumptions. Hallucinations can look and read like a correct and accurate answer, but are factually incorrect, and may be entirely fabricated.
The Future of ChatGPT
Similar to a phone’s auto-complete feature, ChatGPT uses a prediction model to guess the most likely next word based on the context it has been provided. 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. In August 2025, OpenAI released GPT-5, its fastest and smartest model to date, and the current language model for ChatGPT. OpenAI claims that GPT-5 outperforms past models in math, real-world coding, multimodal understanding and health knowledge, and is also less likely to hallucinate or make false claims.
GPT-5 features a “real-time router” that dynamically selects the optimal mode for each query based on its complexity and intent, preserving deep reasoning capacity for challenging requests. It also introduces user-selectable “personalities”, which include Cynic, Robot, Listener and Nerd. There’s also ChatGPT’s Advanced Voice Mode, powered by GPT-4o, which also makes conversations feel more natural, and it works in real time. You can interrupt, adjust the flow, and even have the model respond to emotions in your voice. It’s available to ChatGPT Plus and Team users, while free users get limited access with usage caps. This update allows users to interact with ChatGPT via speech, and to upload images that the model can analyze and use to generate outputs.
Is ChatGPT accurate?
Advanced voice mode becomes available on web browsers — before, it could only be accessed on mobile and desktop formats. The feature is also still exclusive to ChatGPT users who have a Plus, Team, Enterprise or Education plan. 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. The new feature helps students engage more effectively with study materials by altering how it responds when it is enabled. For example, ChatGPT will offer hints, organize content into sections and create custom lessons and quizzes instead of providing a direct answer to students.
OpenAI announces the release of its o1 model, which demonstrates complex reasoning capabilities. To kick off the start of its o1 model family, OpenAI also announces the limited release of its o1-preview and o1-mini models. ChatGPT was created by OpenAI and released in November 2022, and has since become a benchmark for accessible, general-purpose AI applications in people’s personal and professional lives. GPTs are custom versions of ChatGPT, designed for specific tasks or purposes. You can browse through existing GPTs in the GPT store, or create your own to suit your project and needs. It is designed to autonomously interact with websites using its own browser.
How to use ChatGPT: A beginner’s guide to the most popular AI chatbot
Racism, sexism and all manner of prejudices run rampant online, and it is up to the individual to decide how much weight to give it. So, despite the guardrails OpenAI has put in place to prevent it, the chatbot still has a tendency to let biases creep into its outputs. ChatGPT’s reliance on data found online makes it vulnerable to false information, which in turn can impact the veracity of its statements. This often leads to what experts call “hallucinations,” where the output generated is stylistically correct, but factually wrong.
Over time, it spawned a for-profit subsidiary (OpenAI Global LLC) to attract capital investment, with Microsoft as a major backer. GPT-5 was launched on August 7, 2025, and is publicly accessible through ChatGPT, Microsoft Copilot, and via OpenAI’s API. You don’t need to create an account to use ChatGPT, and you can try it out with a free plan before deciding to upgrade.
