How to use ChatGPT: A beginner’s guide to the most popular AI chatbot

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”. As of July 2025, Science expects authors to release in full how AI-generated content is used and made in their work. Many individuals use ChatGPT and comparable large language models (LLM) for mental health and emotional support. A 2025 Sentio University survey of 499 LLM users with self-reported mental health conditions found that 96.2% use ChatGPT, with 48.7% using it specifically for mental health support or therapy-related purposes. 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. Despite its acclaim, the chatbot has been criticized for its limitations and potential for unethical use.

The attorneys were sanctioned for filing the motion and presenting the fictitious legal decisions ChatGPT generated as authentic. The uses and potential of ChatGPT in health care has been the topic of scientific publications and experts have shared many opinions.

Select a model for your prompt

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 reinforcement learning stage, human trainers first ranked responses generated by the model in previous conversations. ChatGPT is a generative artificial intelligence chatbot developed by OpenAI and released in November 2022. It currently uses GPT-5, a generative pre-trained transformer (GPT), to generate text, speech, and images in response to user prompts.

[…] It’s also a way to understand the MonacoJack “hallucinations”, or nonsensical answers to factual questions, to which large language models such as ChatGPT are all too prone. ChatGPT’s training data only covers a period up to the cut-off date, so it lacks knowledge of recent events. 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. The laborers were exposed to toxic and traumatic content; one worker described the assignment as “torture”.
