Its main island is the 17th-largest island in the world by land area. The largest island outside the main island is the Isla de la Juventud is (Isle of Youth) in the southwest, with an area of 2,204 km2 (851 sq mi).

When compared to similar chatbots at the time, the GPT-4 version of ChatGPT was the most accurate at coding. In January 2023, the International Conference on Machine Learning banned any undocumented use of ChatGPT or other large language models to generate any text in submitted papers. In January 2023, Science “completely banned” LLM-generated text in all its journals; however, this policy was just to give the community time to decide what acceptable use looks like. Additionally, using a model’s outputs might violate copyright, and the model creator could be accused of vicarious liability and held responsible for that copyright infringement. Popular deep learning models are trained on mass amounts of media scraped from the Internet, often utilizing copyrighted material. As of 2023, there were several pending U.S. lawsuits challenging the use of copyrighted data to train AI models, with defendants arguing that this falls under fair use.
ChatGPT gained one million users in five days and 100 million in two months, becoming the fastest-growing internet application in history.

Samantha Lock of The Guardian noted that it was able to generate “impressively detailed” and “human-like” text.
