Chat GPT( Chat Generative Pre- trained Motor) is a chatbot developed by Open AI and launched in November 2022. It's built on top of Open AI's GPT- 3 family of large language models and has been fine- tuned( an approach to transfer knowledge) using both supervised and bolstering learning ways. 

Chat GPT was launched as a prototype on November 30, 2022, and snappily garnered attention for its detailed responses and articulate answers across  multitudinous disciplines of knowledge. Its uneven factual delicacy, still, was linked as a significant drawback. Following the release of Chat GPT, Open AI's valuation was estimated at us$ 29 billion. 

Chat GPT – a generative pre- trained motor( GPT) – was fine- tuned( an approach to transfer knowledge on top of GPT-3.5 using supervised knowledge as well as bolstering knowledge. Both approaches used mortal trainers to meliorate the model's performance. In the case of supervised knowledge, the model was handed with exchanges in which the trainers played both sides the  user and the AI assistant. In the  bolstering knowledge step, mortal trainers first ranked responses that the model had created in a former discussion. These rankings were used to produce' reward models' that the model was further fine- tuned on using several duplications of Proximal Policy Optimization( PPO). Proximal Policy Optimization algorithms present a cost-effective benefit to trust region policy optimization algorithms; they negate  multitudinous of the computationally precious operations with faster performance. The models were trained in collaboration with Microsoft on their Azure supercomputing structure.

 In addition, Open AI continues to gather data from Chat GPT users that could be used to further train and fine- tune Chat GPT.
