We’ve trained a model called ChatGPT which interacts in a conversational way. The dialogue format makes it possible for ChatGPT to answer followup questions, admit its mistakes, challenge incorrect premises, and reject inappropriate requests.

Starting today, you can use ChatGPT instantly, without needing to sign-up. We’re rolling this out gradually, with the aim to make AI accessible to anyone curious about its capabilities. We may use what you provide to ChatGPT to improve our models for everyone.

ChatGPT is a generative AI chatbot developed by OpenAI. Originally released on November 30, 2022, the product uses large language models —specifically generative pre-trained transformers (GPTs)—to generate text, speech, and images in response to user prompts.
