GPT stands for Generative Pretrained Transformer. It is a deep learning model developed by OpenAI that uses unsupervised learning to generate text based on a large corpus of data. The model is trained on a massive amount of text data and can then be fine-tuned for specific tasks, such as language translation, question-answering, or text completion.
GPT-3 (Generative Pretrained Transformer 3) is the latest version of the model and is one of the largest and most advanced language models to date, with over 175 billion parameters. GPT-3 has received a lot of attention due to its ability to generate human-like text and perform a variety of language tasks with high accuracy.
