This includes text-to-image models such as Stable Diffusion and large language models such as ChatGPT. As of 2023, there were several pending U.S. lawsuits challenging the use of copyrighted data to train AI models, with defendants arguing that this falls under fair use. It can also critique the user’s writing, summarize long documents and translate text from one language to another. 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.
ChatGPT is the artificial intelligence chatbot that started the whole generative AI revolution. The integration used ChatGPT to write prompts for DALL-E guided by conversations with users. In March 2025, OpenAI updated ChatGPT to generate images using GPT-4o instead of DALL-E. In my experience, the web version offers the fullest range of features available. There’s even a Projects feature that keeps all your chats organized, plus a Library to manage all your generated images.

Accessibility and integrations

OpenAI CEO Sam Altman said that users were unable to see the contents of the conversations. ChatGPT’s training data only covers a period up to the cut-off date, so it lacks knowledge of recent events. This tool allows a user to customize ChatGPT’s behavior for a specific use case.

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. 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). In the case of supervised learning, the trainers acted as both the user and the AI assistant. In the reinforcement learning stage, human trainers first ranked responses generated by the model in previous conversations.

The company announced a slew of generative AI-powered features to counter OpenAI and Microsoft. In July, OpenAI released ChatGPT agent, an AI agent that can perform multi-step tasks. It is capable of writing software, answering codebase questions, running tests, and proposing pull requests. The languages tested were Polish, French, Korean, Spanish, Arabic, Tagalog, and Amharic. For more common languages, AI translators like ChatGPT did better than Google Translate, while for „niche” languages (Amharic and Tagalog), Google Translate performed better. None of the tested services were a perfect replacement for a fluent human translator.

Users interact with ChatGPT through conversations which consist of text, audio, and image inputs and outputs. OpenAI collects data from ChatGPT users to further train and fine-tune its services.

Is ChatGPT Free?

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. 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. OpenAI has attempted to address these issues with enhanced data protection measures. Your prompts (on Free, Plus and Pro plans) may be used to train the model unless you opt out in settings.

ChatGPT is becoming a default interface for how people interact with AI and even how they get information from the internet. ChatGPT faces ongoing legal challenges related to industry concerns regarding the ethics and the legality of data sourcing for AI training. „You can create systems that can fool people into thinking that this thing that you’re talking to is human,” Jaffri tells CNET. That’s one reason why it sometimes „hallucinates” or generates confident-sounding but incorrect information. It was Romibet trained on massive amounts of data from books and the internet — websites, Wikipedia, Reddit threads, news sites and much, much more.

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. GPT-5 was launched on August 7, 2025, and is publicly accessible through ChatGPT, Microsoft Copilot, and via OpenAI’s API. Released in February 2025, GPT-4.5 was described by Altman as a „giant, expensive model”. In March 2023, a bug allowed some users to see the titles of other users’ conversations.
