what is chat gbt

ChatGPT is an artificial intelligence (AI) chatbot developed by OpenAI and launched on November 30, 2022. It is a large language model-based chatbot that uses natural language processing to create human-like conversational dialogue. ChatGPT is built upon either GPT-3.5 or GPT-4, members of OpenAIs proprietary series of generative pre-trained transformer (GPT) models, based on the transformer architecture developed by Google. It is fine-tuned for conversational applications using a combination of supervised and reinforcement learning techniques. ChatGPT enables users to refine and steer a conversation towards a desired length, format, style, level of detail, and language used. Successive prompts and replies, known as prompt engineering, are considered at each conversation stage as a context. ChatGPT is similar to the automated chat services found on customer service websites, as people can ask it questions or request clarification to ChatGPT's replies. The GPT stands for "Generative Pre-trained Transformer," which refers to how ChatGPT processes requests and formulates responses. ChatGPT is trained with reinforcement learning through human feedback and reward models that rank the best responses. This feedback helps augment ChatGPT with machine learning to improve future responses.
