OpenAI supports limited, no-login access in many regions, so you can try ChatGPT instantly. Apart from models, there are modes and tools in ChatGPT that allow you to go beyond basic chatting. There’s even a Projects feature that keeps all your chats organized, plus a Library to manage all your generated images. OpenAI announces the release of its o1 model, which demonstrates complex reasoning capabilities. For example, the new model doubles its context window from 128,000 tokens in GPT-4o to 256,000 tokens in GPT-5.
Who Created ChatGPT?
- {
- Users interact with ChatGPT through conversations which consist of text, audio, and image inputs and outputs.
- This often leads to what experts call “hallucinations,” where the output generated is stylistically correct, but factually wrong.
- The AI chatbot tries its best to avoid explicit, violent or discriminatory content.
- 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 faces ongoing legal challenges related to industry concerns regarding the ethics and the legality of data sourcing for AI training.
- In 2025, OpenAI added several features to make ChatGPT more agentic (capable of autonomously performing longer tasks).

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. In March 2023, OpenAI announced GPT-4, the latest version of its language model. Developed by OpenAI, the AI chatbot became a hugely popular tool almost overnight. 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.
Accessibility and integrations
- OpenAI supports limited, no-login access in many regions, so you can try ChatGPT instantly.
- 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.
- ChatGPT became one of the fastest-growing apps in history, amassing hundreds of millions of users.
- If you prefer to keep using Dall-E 3 (its first image generator), you can still access it through the Dall-E GPT.
- There’s even a Projects feature that keeps all your chats organized, plus a Library to manage all your generated images.
- It was trained on massive amounts of data from books and the internet — websites, Wikipedia, Reddit threads, news sites and much, much more.

This tool allows a user to customize ChatGPT’s behavior for a specific use case. Users interact with ChatGPT through conversations which consist of text, audio, and image inputs and outputs. The paid experience is faster and more accurate than the free tier, turning up better quality responses across a range of queries and topics. The AI chatbot tries its best to avoid explicit, violent or discriminatory content. It can create personalized workout plans, generate business ideas and even act as your therapist.
Edit, Translate and Summarize Content
However, it was labeled underwhelming by some users due its performance shortly after its release. 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. In August 2025, OpenAI released GPT-5, its fastest and smartest model to date, and the current language model for ChatGPT.

- As of 2025, ChatGPT’s website is among the 5 most-visited websites globally, and has over 800 million active weekly users.
- The languages tested were Polish, French, Korean, Spanish, Arabic, Tagalog, and Amharic.
- 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.
- OpenAI CEO Sam Altman said that users were unable to see the contents of the conversations.
- 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.
- 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.

Paid tier
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.
Regional responses
Robin Bauwens, an assistant professor at Tilburg University, found that a ChatGPT-generated peer review report on his article mentioned nonexistent studies. 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. The company announced a slew of generative AI-powered features to counter OpenAI and Microsoft. GPT-5 was launched on August 7, 2025, and is publicly accessible through ChatGPT, Microsoft Copilot, and via OpenAI’s API.

OpenAI collects data from ChatGPT users to further train and fine-tune its services. The laborers were exposed to toxic and traumatic content; one worker described the assignment as „torture“. OpenAI’s outsourcing partner was Sama, a training-data company based in San Francisco, California. NYXBets casino ZDNET’s recommendations are based on many hours of testing, research, and comparison shopping.

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 2025, OpenAI added several features to make ChatGPT more agentic (capable of autonomously performing longer tasks).
