In the case of supervised learning, the model was provided with conversations in which the trainers played both sides: the user and the AI assistant. Both approaches use human trainers to improve the model's performance. The fine-tuning process leveraged both supervised learning as well as reinforcement learning in a process called reinforcement learning from human feedback (RLHF). It is a task-specific GPT that was fine-tuned to target conversational usage, and was primarily built upon an improved version of OpenAI's GPT-3 model known as " GPT-3.5". Part of a series onĬhatGPT is a member of the generative pre-trained transformer (GPT) class of language models.
Users on the free tier have access to the GPT-3.5 model, while paid subscribers to ChatGPT Plus have limited access to the more-advanced GPT-4 model. The chatbot is operated on a freemium model. Within months, other businesses accelerated competing LLM products such as Google PaLM-E, Baidu ERNIE, and Meta LLaMA.

īy 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. However, a notable drawback has been its tendency to confidently provide inaccurate information. ChatGPT is built upon OpenAI's foundational GPT models, specifically GPT-3.5 and GPT-4, and has been fine-tuned for conversational applications using a combination of supervised and reinforcement learning techniques.ĬhatGPT was launched on November 30, 2022, and gained attention for its detailed and articulate responses spanning various domains of knowledge.
ChatGPT is an artificial intelligence chatbot developed by OpenAI based on the company's Generative Pre-trained Transformer (GPT) series of large language models (LLMs).
