ChatGPT is a variant of the GPT (Generative Pre-training Transformer) language model that has been fine-tuned for the task of conversational language modeling. It is designed to generate human-like text in response to prompts provided by users, allowing it to engage in natural language conversations on a wide range of topics. ChatGPT is trained on a large dataset of human conversations and can generate responses that are coherent, contextually relevant, and appropriate for the given context. It can be used for tasks such as generating responses to customer inquiries, creating chatbot dialogue, or generating text for language translation systems. (Description written by ChatGPT)
