It was trained on massive amounts of data from books and the internet — websites, Wikipedia, Reddit threads, news sites and much, much more. 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.
What can you do with ChatGPT?
Released Rolldorado in February 2025, GPT-4.5 was described by Altman as a «giant, expensive model». It is capable of writing software, answering codebase questions, running tests, and proposing pull requests. The languages tested were Polish, French, Korean, Spanish, Arabic, Tagalog, and Amharic. For more common languages, AI translators like ChatGPT did better than Google Translate, while for «niche» languages (Amharic and Tagalog), Google Translate performed better. None of the tested services were a perfect replacement for a fluent human translator.

At the time, Copilot boasted several other features over ChatGPT, such as access to the internet, knowledge of current information, and footnotes.

They can explicitly tell ChatGPT to remember aspects of the conversation, and ChatGPT can use these details in future conversations.
