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.

- In 2025, OpenAI added several features to make ChatGPT more agentic (capable of autonomously performing longer tasks).
- In March 2025, OpenAI updated ChatGPT to generate images using GPT-4o instead of DALL-E.
- This has led to concern over the rise of what has come to be called “synthetic media” and “AI slop” which are generated by AI and rapidly spread over social media and the internet.
- Many individuals use ChatGPT and comparable large language models (LLM) for mental health and emotional support.

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.” 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. OpenAI CEO Sam Altman said that users were unable to see the contents of the conversations.

GPT-5 was launched on August 7, 2025, and is publicly accessible through ChatGPT, Microsoft Copilot, and via OpenAI’s API. In 2025, OpenAI added several features to make ChatGPT more agentic (capable of autonomously performing longer tasks). 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. 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.

It can generate plausible-sounding but incorrect or nonsensical answers known as hallucinations. 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. Despite decades of using AI, Wall Street professionals report that consistently beating the market with AI, including recent large language models, is challenging due to limited and noisy financial data.

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. ChatGPT was initially free to the public, and OpenAI planned to monetize the service later.
