ChatGPT is an open-source AI chatbot developed by OpenAI, a research laboratory focused on creating artificial general intelligence (AGI). This chatbot uses natural language processing (NLP) to generate responses to input text, allowing it to have conversations with humans just like any other conversation partner. It is trained using deep learning methods, meaning it is capable of understanding complex sentences and responding accordingly.

ChatGPT Online was designed to be able to handle a wide variety of conversations, from small talk to more complex topics such as politics or science. This makes it particularly useful for customer service settings where quick responses are required for common queries. It can also be used for more creative applications such as story writing or even creating virtual assistants for personal use.
