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. OpenAI will, by default, use your conversations with the free chatbot to train data and refine its models. Recently, OpenAI made ChatGPT’s image generation capabilities free for all users, albeit with a limited number of monthly uses.
Privacy concerns, legal battles and other controversies

- 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 is based on GPT foundation models that have been fine-tuned for conversational assistance.
- ChatGPT is a chatbot and AI assistant built on large language model technology.
- 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.
- Some, including Nature and JAMA Network, “require that authors disclose the use of text-generating tools and ban listing a large language model (LLM) such as ChatGPT as a co-author”.
- Researchers suggested this was due to its higher ability to capture the context.

A 2023 study reported that GPT-4 obtained a better score than 99% of humans on the Torrance Tests of Creative Thinking. Stanford researchers reported that GPT-4 “passes a rigorous Turing test, diverging from average human behavior chiefly to be more cooperative.” GPT-5 was launched on August 7, 2025, and is publicly accessible through ChatGPT, Microsoft Copilot, and via OpenAI’s API.

- The chatbot can facilitate academic dishonesty, generate misinformation, and create malicious code.
- GPT-4o is OpenAI’s latest, fastest, and most advanced flagship model.
- The tool can be called on manually or activated whenever a user prompt could benefit from web-based information.
- OpenAI has sometimes mitigated this effect by updating the training data.
- It currently uses GPT-5, a generative pre-trained transformer (GPT), to generate text, speech, and images in response to user prompts.
- The integration used ChatGPT to write prompts for DALL-E guided by conversations with users.

How to use ChatGPT
ChatGPT runs on a large language model (LLM) architecture created by OpenAI called the Generative Pre-trained Transformer (GPT). Now, the free version runs on GPT-4o mini, with limited access to GPT-4o. Microsoft’s Copilot offers free image generation, also powered by DALL-E 3, in its chatbot. These fears even led some school districts to block access when ChatGPT initially launched. As of this writing, ChatGPT’s main models are GPT-5, GPT-5 mini, and GPT-5 nano.
- 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.
- Originally based on OpenAI’s GPT-3 architecture, ChatGPT has evolved.
- For example, your chatbot can answer common IT support questions right through your organization’s internal site or Slack.
- OpenAI CEO Sam Altman said that users were unable to see the contents of the conversations.
- The generative AI tool can answer questions and assist you with composing text, code, and much more.
- Furthermore, it provided false positives 9% of the time, incorrectly identifying human-written work as AI-produced.

Is ChatGPT free?
The chatbot can facilitate academic dishonesty, generate misinformation, and create malicious code. The ethics of its development, particularly the use of copyrighted content as training data, have also drawn controversy. Over a month after the announcement, Google began rolling out access to Bard first via a waitlist. Therefore, if you are an avid Google user, Gemini might be the best AI chatbot for you. Generative AI models are also subject to hallucinations, which can result in inaccurate responses. For example, your chatbot can answer common IT support questions right through your organization’s internal site Rolldorado or Slack.
