ChatGPT is a service by OpenAI, and in it’s own words:
ChatGPT is an AI-based conversational agent developed by OpenAI. It belongs to the family of Generative Pre-trained Transformers (GPT) models, specifically GPT-3.5 in its latest version. ChatGPT is designed to engage in natural language conversations with users, offering responses and generating text based on the input it receives.
Using a vast amount of text data from the internet, ChatGPT has been trained to understand and generate human-like text across a wide range of topics and contexts. It can provide information, answer questions, hold conversations, and even generate creative content like stories or poems.
The primary goal of ChatGPT is to assist users in various tasks, provide information, entertain, and engage in natural language interactions, making it a versatile tool for a variety of applications, from customer service to language learning and beyond. [1]
ChatGPT is available at https://chat.openai.com/. There is a free version based on currently version 3.5. Version 4.0, including a number of additional language models, are available as a subscription service.
DTU gives access for students and employees to a somewhat similar language model from Microsoft, which you can find at https://copilot.microsoft.com/. Note that Microsoft is co-owner of OpenAI.
See the Microsoft Copilot page for more info.
