Chat.com

Chat.com is the domain OpenAI acquired that now redirects to ChatGPT. ChatGPT is a dialogue generation model trained by OpenAI and released on November 30, 2022, described in the listing as a sibling model to InstructGPT, which was trained to follow instructions in prompts and provide detailed responses. The interaction is conversational: you can ask follow-up questions, and the model is described as able to acknowledge errors, challenge incorrect premises, and refuse inappropriate requests. It answers technical questions such as code fixes and mathematical theorem explanations, generates poetry and humorous content, and produces personalized text through templates such as a self-introduction letter. Safety and content filtering are built in.

- Hold a multi-turn conversation with follow-up questions

- Get explanations of technical topics including code and mathematics

- Generate creative output such as poetry and humor

- Produce templated text such as a formal letter

- Rely on content filtering for safer output

The audience is anyone who wants a conversational assistant in the browser. The examples are a user asking a coding question and getting possible solutions, a user requesting a plain-language explanation of a mathematical theorem, and a user asking for a formal self-introduction letter and receiving a template plus generated text. That covers developers, students, and writers. Because the model handles both technical and creative requests in the same thread, it works as a general-purpose assistant rather than a specialist tool.

The listing describes free availability during the research preview period, and terms have changed since, so check current access and pricing on the site rather than assuming the original free model still applies. Answers can be confidently wrong, so verify anything you plan to rely on, particularly code, figures, and factual claims. The model refuses some requests, which is a feature for safety but can be limiting at the edges of a legitimate task. Finally, generated text is a draft: it needs your review for accuracy, tone, and anything that will be published under your name.
