Introduction
Chat GPT (Chat Generative Pre-trained Transformer) is a trained language model and a chatbot which interacts conversationally.
It is launched by Open AI in November 2022.
It can perform things like answering questions, followups, admits its mistakes, reject inappropriate questions or requests and it can even write and debug computer based programs.
Its a sibling model for InstructGPT which also is a trained model to follow an instruction in a prompt and can provide us with detailed information and response. In comparison to InstructGPT, ChatGPT attempts to reduce harmful and deceitful responses.
In January 2023, ChatGPT reached over 100 million users, It is free for now and can be accessed using the below link, but this does not mean that Open AI promises for free trial in future.
Some of the conversational responses are mentioned below for better understanding how chat GPT provides answers to user questions.
1) What is full form of PHP?
A) The full form of PHP is Hypertext Preprocessor.
2) What is India's capital?
A) The capital of India is New Delhi.
3) Top country in the world in terms of technology?
A) It's difficult to determine a single country that is the "top" in terms of technology, as it depends on how you measure and define technology. However, some commonly recognized leaders in the field include the United States, Japan, South Korea, Germany, and China. These countries have a combination of factors such as investment in research and development, a highly educated workforce, and a supportive business environment for technology companies.
Open AI has trained this model using Reinforcement Learning from Human Feedback (RLHF), using the same methods as InstructGPT but data collection setup differs among both. An initial model is trained using supervised fine-tuning: human AI trainers provided conversations in which they played both sides i.e., the user and an AI assistant.
Trainers are given with access to model-written suggestions to help them compose their responses. Also mixed this new dialogue dataset with the InstructGPT dataset, which they transformed into a dialogue format.
Chat GPT bot is powered by large amounts of computational data and various techniques to make predictions to string words together in a meaningful way. Along with vocabulary and information, it can also also understand words in context. This helps them mimic speech patterns while dispatching an encyclopedic knowledge.
Limitations
1. ChatGPT may sometimes writes plausible-sounding but incorrect answers.
2. ChatGPT is most sensitive to tweaks to the input phrasing or attempting the same prompt multiple times.
3. Chat GPT asks clarification for the questions entered by the user when they are ambiguous.
