chat gpt ai

ChatGPT is an artificial intelligence (AI) chatbot developed by OpenAI and released in November 2022. The name "ChatGPT" combines "Chat", referring to its chatbot functionality, and "GPT", which stands for Generative Pre-trained Transformer, a type of large language model (LLM). ChatGPT is built upon OpenAI's foundational GPT models, specifically GPT-3.5 and GPT-4, and has been fine-tuned (an approach to transfer learning) for conversational applications using a combination of supervised and reinforcement learning techniques.
ChatGPT was launched on November 30, 2022, and gained attention for its detailed and articulate responses spanning various domains of knowledge. However, a notable drawback has been its tendency to confidently provide inaccurate information.By January 2023, it had become the fastest growing consumer software application in history, gaining over 100 million users and contributing to OpenAI's valuation growing to US$29 billion. The introduction of ChatGPT has spurred competition in the field, leading to the accelerated development of Google's chatbot Bard, initially based on LaMDA and later on PaLM, as well as Meta AI's foundation model LLaMA, which serves as a basis for other chatbot creations.
The chatbot is operated on a freemium model, where users on the original, free tier only have access to GPT-3.5, while ChatGPT Plus users also have access to GPT-4, albeit on a limited basis.
