Full form of GPT | What does GPT stand for in ChatGPT?
GPT Full Form – The full for GPT is Generative Pre-trained Transformer. The most recent language model, Chat GPT, is an Open AI that was created and trained exclusively for conversational engagements. Sam Altman’s OpenAI released ChatGPT on November 30. It is built on top of OpenAI’s GPT-3 family of large language models and is fine-tuned (an approach to transfer learning with both supervised and reinforcement learning techniques. ChatGPT was launched as a prototype and quickly garnered attention for its detailed responses and articulate answers across many domains of knowledge. Its uneven factual accuracy was identified as a significant drawback.
Both approaches used human trainers to improve the model’s performance. 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. In the reinforcement step, human trainers first ranked responses that the model had created in a previous conversation. These rankings were used to create ‘reward models’ that the model was further fine-tuned on using several iterations of Proximal Policy Optimization (PPO).
Unlike most chatbots, ChatGPT remembers previous prompts given to it in the same conversation; journalists have suggested that this will allow ChatGPT to be used as a personalized therapist. To prevent offensive outputs from being presented to and produced from ChatGPT, queries are filtered through OpenAI’s company-wide moderation API, and potentially racist or sexist prompts are dismissed. The service was initially free to the public, with plans to monetize the service later. By December 4, OpenAI estimated ChatGPT already had over one million users.
