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. 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. Here’s how it works, its use cases, how to access it, its limitations, notable updates and future outlook. In March 2023, a bug allowed some users to see the titles of other users’ conversations.
Answer Questions
The Pro launch coincided with the release of the o1 model, providing unlimited access to o1 and advanced voice mode. In March 2025, OpenAI updated ChatGPT to generate images using GPT-4o instead of DALL-E. Users interact with ChatGPT through conversations which consist of text, audio, and image inputs and outputs.

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. OpenAI announced that it is letting users buy goods directly in ChatGPT through a feature called Instant Checkout. 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. Through the partnership, ChatGPT users will be able to find products sold by Walmart and complete entire purchases without leaving the chatbot’s interface. 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.
Is ChatGPT Free?
- As of 2025, ChatGPT’s website is among the 5 most-visited websites globally, and has over 800 million active weekly users.
- The integration used ChatGPT to write prompts for DALL-E guided by conversations with users.
- 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.
- It can generate plausible-sounding but incorrect or nonsensical answers known as hallucinations.
- ChatGPT is based on GPT foundation models that have been fine-tuned for conversational assistance.
- Robin Bauwens, an assistant professor at Tilburg University, found that a ChatGPT-generated peer review report on his article mentioned nonexistent studies.

ChatGPT is an artificial intelligence chatbot capable of having conversations with people and generating unique, human-like text responses. Many individuals use ChatGPT and comparable large language models (LLM) for mental health and emotional support. 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 based on GPT foundation models that have been fine-tuned for conversational assistance. The fine-tuning process involved supervised learning and reinforcement learning from human feedback (RLHF).

This could enable ChatGPT to keep track of larger documents and conversations, and to handle more complex projects. 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. In June 2023, hundreds of people attended a “ChatGPT-powered church service” at St. Paul’s Church in Fürth, Germany. Geoffrey Hinton, one of the “fathers of AI”, voiced concerns that future AI systems may surpass human intelligence. ChatGPT also provided an outline of how human reviewers are trained to reduce inappropriate content and to attempt to provide political information without affiliating with any political position. ChatGPT’s training data only covers a period up to the cut-off date, so it lacks knowledge of recent events.
Languages
ChatGPT is due for more upgrades in the near future, with the advanced voice mode potentially receiving a live camera feature to create even more seamless interactions. AI agents represent stage three of AGI, enhancing ChatGPT’s reasoning abilities and enabling it to complete a broader range of tasks without human assistance. The feature is also still exclusive to ChatGPT users who have a Plus, Team, Enterprise or Education plan. OpenAI announces the ChatGPT Pro plan, a new premium plan for ChatGPT users to access even more features. For example, ChatGPT will offer hints, organize content into sections and create custom lessons and quizzes instead of providing a direct answer to students. For example, the new model doubles its context window from 128,000 tokens in GPT-4o to 256,000 tokens in GPT-5.
GPT-4, which was released on March 14, 2023, was made available via API and for premium ChatGPT users. 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. The laborers were exposed to toxic and traumatic content; one worker described the assignment as “torture”. OpenAI’s outsourcing Crowngreen casino partner was Sama, a training-data company based in San Francisco, California.

By January 2023, ChatGPT had become the fastest-growing consumer software application in history, gaining over 100 million users in two months. As of 2025, ChatGPT’s website is among the 5 most-visited websites globally, and has over 800 million active weekly users.
They can explicitly tell ChatGPT to remember aspects of the conversation, and ChatGPT can use these details in future conversations. OpenAI announces the release of its o1 model, which demonstrates complex reasoning capabilities. OpenAI announced the addition of product recommendations on ChatGPT when users implied shopping intent in their queries. While users cannot checkout inside ChatGPT, they are redirected to the merchant’s website when they click on the link. Teachers are concerned that students will use it to cheat, prompting some schools to completely block access to it.

OpenAI said it has taken steps to effectively clarify and address the issues raised; an age verification tool was implemented to ensure users are at least 13 years old. Despite this, users may “jailbreak” ChatGPT with prompt engineering techniques to bypass these restrictions. These limitations may be revealed when ChatGPT responds to prompts including descriptors of people. In one instance, ChatGPT generated a rap in which women and scientists of color were asserted to be inferior to white male scientists. ChatGPT Team lets companies create shared workspaces with settings that apply to all users, as well as the ability to share proprietary data sets.
