The plan costs $200 per month and gives users access to Open AI 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.

• We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites.
• 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).
• For instance, if you ask ChatGPT a question like “What sites should I see in my upcoming vacation to Paris?
• These hallucinations are compression artifacts, but … they are plausible enough that identifying them requires comparing them against the originals, which in this case means either the Web or our knowledge of the world.
• 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.

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.

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”.

Who created ChatGPT?

The release of GPT-5 provides a sizable update to previous models, at least on paper. For example, the new model doubles its context window from 128,000 tokens in GPT-4o to 256,000 tokens in GPT-5. This could enable ChatGPT to keep track of larger documents and conversations, and to handle more complex projects. GPT-5 also added enhanced multimodal capabilities with improvements to email, calendar and code environment integrations.

• The newest version of OpenAI’s image generator, DALL-E, was made available to ChatGPT Plus and Enterprise users.
• People can use ChatGPT for advice on their relationships, finances and even their health.
• And several authors and journalists have sued OpenAI for copyright infringement, claiming their work was scraped from the internet and used as training data without their permission.
• While both the site and app allow you to access custom GPTs, some features, like the Sora video generator, are currently exclusive to the web browser.
• 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.

What is ChatGPT Operator?

In this guide, I’ll show you how to get started and make the most of ChatGPT for whatever you need. The newest version of OpenAI’s image generator, DALL-E, was made available to ChatGPT Plus and Enterprise users. Despite these clear advances compared to prior models, GPT-5 is still susceptible to the same problems that plagued its predecessors. In fact, many users have reported instances of GPT-5 making simple mistakes. Others have stated that there is no observable difference from its predecessors. Most people know that, just because something is on the internet, that doesn’t make it true.

The platform can be accessed through its website, mobile app and some third-party integrations. The AI is free to use at its full capability for a limited number of prompts. After this, users will have access to a less powerful version, or can upgrade to GPT Plus for single use, or GPT Team, which is designed for teams and businesses to collaborate using the tool. Equally adept at planning, task assistance and adding needed context, it chart of accounts definition is being used across a wide range of private and public sector organisations. At its core, ChatGPT belongs to the field of natural language processing (NLP), which equips machines with the ability to interpret and generate human language. This is a large language model (LLM) which learns from vast amounts of text, much of which is sourced from the internet and physical written work, and is fine-tuned through human interaction.

The paid version of ChatGPT also offers features like image and voice inputs and integrations with other OpenAI services like the image generator DALL-E. The language models used in ChatGPT are specifically optimized for dialogue and were trained using reinforcement learning from human feedback (RLHF). 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). Released by artificial intelligence company OpenAI in 2022, ChatGPT is a chatbot capable of communicating with users in a human-like way. But, because the approximation is presented in the form of grammatical text, which ChatGPT excels at creating, it’s usually acceptable.

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.

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.

The process happens iteratively, building from words to sentences, to paragraphs, to pages of text. ChatGPT is a chatbot created by OpenAI that can process text, image, audio and video data to answer questions, solve problems and more. Here’s how it works, its use cases, how to access it, its limitations, notable updates and future outlook.

App support

Custom instructions allow users to save directions that apply to all interactions, rather than adding them to every request. To do so, download the ChatGPT app from the App Store for iPhone and iPad devices, or from Google Play for Android devices. 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). Though often impressively accurate, ChatGPT can produce confident-sounding yet incorrect answers, known as AI hallucinations.

Based on internal evaluations, GPT-5 outperforms its predecessors in multiple areas, including math, coding, visual perception and health knowledge. It is now available to both paying and non-paying ChatGPT users, with usage limitations of course. However, it was labeled underwhelming by some users due its performance shortly after its release. ChatGPT’s impressive writing abilities have not gone without some controversy.

To get started with ChatGPT, simply head to chat.openai.com or download the mobile app from the Apple App Store or Google Play Store. While both the site and app allow you to access custom GPTs, some features, like the Sora video generator, are currently exclusive to the web browser.

I did 24 days of coding in 12 hours with a $20 AI tool – but there’s one big pitfall

ChatGPT is an artificial intelligence chatbot capable of having conversations with people and generating unique, human-like text responses. 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. 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. It can also critique the user’s writing, summarize long documents and translate text from one language to another.

Instead of a list of websites, though, it’ll provide users with a simple list of answers. For instance, if you ask ChatGPT a question like “What sites should I see in my upcoming vacation to Paris? People can use ChatGPT for advice on their relationships, finances and even their health.

Teachers are concerned that students will use it to cheat, prompting some schools to completely block access to it. And several authors and journalists have sued OpenAI for copyright infringement, claiming their work was scraped from the internet and used as training data without their permission. At $200 per month, the plan is intended to give users access to OpenAI’s latest offering, the o1 model family.

This update allows ChatGPT to remember details from previous conversations and tailor its future responses accordingly. This can include factual information — like dietary restrictions or relevant details about the user’s business — as well as stylistic preferences like brevity or a specific kind of outline. According to an OpenAI blog post, ChatGPT will build memories on its own over time, though users can also prompt the bot to remember specific details — or forget them.

The platform also collects user email addresses, IP addresses, device identifiers, cookie information and location data, and may be required to share data with affiliates or government bodies, but not advertisers. From individuals to major organisations and governments, ChatGPT has been widely integrated. Matt Weaver, head of solutions engineering for Europe at OpenAI, revealed to Computer Weekly that more than 600 million people use ChatGPT weekly, with the platform processing about one billion messages every day. On top of this, due to the powerful computer chips needed to run ChatGPT, greater power and energy sources are required to maintain the datacentres used to meet the demand of AI. OpenAI was founded in 2015 by a team including CEO Sam Altman, president Greg Brockman and scientist Wojciech Zaremba, along with Elon Musk, Ilya Sutskever and John Schulman, all of whom are no longer part of OpenAI.
