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. 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 a chatbot and AI assistant built on large language model technology. It is designed to generate human-like text and can carry out a wide variety of tasks.

- OpenAI has attempted to address these issues with enhanced data protection measures.
- In late March 2023, the Italian data protection authority banned ChatGPT in Italy and opened an investigation.
- After the upgrade, ChatGPT reclaimed its crown as the best AI chatbot.
- Despite its acclaim, the chatbot has been criticized for its limitations and potential for unethical use.
- ChatGPT runs on a large language model (LLM) architecture created by OpenAI called the Generative Pre-trained Transformer (GPT).
- Users interact with ChatGPT through conversations which consist of text, audio, and image inputs and outputs.

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.
- In the case of supervised learning, the trainers acted as both the user and the AI assistant.
- Now, the free version runs on GPT-4o mini, with limited access to GPT-4o.
- 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.
- We process your data to deliver content or advertisements and measure the delivery of such content or advertisements to extract insights about our website.
- Yes, an official ChatGPT app is available for iPhone and Android users.
- Released in February 2025, GPT-4.5 was described by Altman as a “giant, expensive model”.

How to upload images to ChatGPT from the desktop app
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.
- In March 2023, a bug allowed some users to see the titles of other users’ conversations.
- 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.
- Ask it to enrich new lead data from the internet, add it to your CRM, and draft personalized outreach to leads most likely to convert.
- 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.
- In July, OpenAI released ChatGPT agent, an AI agent that can perform multi-step tasks.

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.
Model versions
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 Rolldorado 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 or Slack.
